GraphQL v2 Connection Details

Introduction

Connector Version

This documentation is based on version 23.0.9036 of the connector.

Get Started

GraphQL Version Support

The connector leverages the GraphQL API to enable bidirectional access to GraphQL.

Establish a Connection

Connect to GraphQL

Set the following to connect:

  • URL: Specify the URL of the GraphQL service, for example https://api.example.com/graphql.
  • Location: Set this to the file path containing any custom defined schemas for the GraphQL service.

Authenticate to GraphQL

The driver supports the following types of authentication:

  • Basic
  • OAuth 1.0 & 2.0
  • OAuthPKCE
  • AWS Cognito Credentials:
    • AwsCognitoSrp
    • AwsCognitoBasic
Basic

Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.

OAuth

In all OAuth flows, you must set AuthScheme to OAuth and OAuthVersion to 1.0 or 2.0. The following sections assume you have done so.

Desktop Applications

After setting the following connection properties, you are ready to connect:

  • OAuthRequestTokenURL: Required for OAuth 1.0. This is the URL where the application makes a request for the request token.
  • OAuthAuthorizationURL: Required for OAuth 1.0 and 2.0. This is the URL where the user logs into the service and grants permissions to the application. In OAuth 1.0 if permissions are granted the request token is authorized.
  • OAuthAccessTokenURL: Required for OAuth 1.0 and 2.0. This is the URL where the request for the access token is made. In OAuth 1.0 the authorized request token is exchanged for the access token.
  • OAuthRefreshTokenURL: Required for OAuth 2.0. In OAuth 2.0 this is the URL where the refresh token is exchanged for a new access token when the old one expires. Note that for your data source this may be the same as the access token URL.
  • OAuthClientId: Set this to the client ID in your application settings. This is also called the consumer key.
  • OAuthClientSecret: Set this to the client secret in your application settings. This is also called the consumer secret.
  • CallbackURL: Set this to http://localhost:33333. If you specified a redirect URL in your application settings, this must match.
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the access token in the connection string.

When you connect, the connector opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

  1. Extracts the access token from the callback URL and authenticates requests.
  2. Refreshes the access token when it expires.
  3. Saves OAuth values in OAuthSettingsLocation. These values persist across connections.
Headless Machines

To create GraphQL data sources on headless servers or other machines on which the connector cannot open a browser, you need to authenticate from another machine. Authentication is a two-step process.

  1. Choose one of two options:
    • Option 1: Obtain the OAuthVerifier value as described in "Obtain and Exchange a Verifier Code" below.
    • Option 2: Install the connector on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow, as described in "Transfer OAuth Settings" below.
  2. Then configure the connector to automatically refresh the access token on the headless machine.

Option 1: Obtain and Exchange a Verifier Code

Set the following properties on the headless machine:

  • InitiateOAuth: Set this to OFF.
  • OAuthClientId: Set this to the application ID in your application settings.
  • OAuthClientSecret: Set this to the application secret in your application settings.

You can then follow the steps below to authenticate from another machine and obtain the OAuthVerifier connection property.

  1. Call the GetOAuthAuthorizationURL stored procedure with the CallbackURL input parameter set to the exact Redirect URI you specified in your application settings.
  2. Save the value of the returned AuthToken and AuthKey if OAuthVersion is set to 1.0. They are used in the next step.
  3. Open the returned URL in a browser. Log in and grant permissions to the connector. You are then redirected to the callback URL, which contains the verifier code.
  4. Save the value of the verifier code. Later, you must set this in the OAuthVerifier connection property.

On the headless machine, set the following connection properties to obtain the OAuth authentication values:

  • OAuthRequestTokenURL: Required for OAuth 1.0. In OAuth 1.0 this is the URL where the application makes a request for the request token.
  • OAuthAuthorizationURL: Required for OAuth 1.0 and 2.0. This is the URL where the user logs into the service and grants permissions to the application. In OAuth 1.0 if permissions are granted the request token is authorized.
  • OAuthAccessTokenURL: Required for OAuth 1.0 and 2.0. This is the URL where the request for the access token is made. In OAuth 1.0 the authorized request token is exchanged for the access token.
  • OAuthRefreshTokenURL: Required for OAuth 2.0. In OAuth 2.0 this is the URL where the refresh token is exchanged for a new access token when the old one expires. Note that for your data source this may be the same as the access token URL.
  • OAuthClientId: Set this to the client ID in your application settings.
  • OAuthClientSecret: Set this to the client secret in your application settings.
  • CallbackURL: Set this to http://localhost:33333. If you specified a redirect URL in your application settings, this must match.
  • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the access token in the connection string.

Connect to Data

After the OAuth settings file is generated, set the following properties to connect to data:

  • OAuthSettingsLocation: Set this to the location containing the encrypted OAuth authentication values. Make sure this location gives read and write permissions to the provider to enable the automatic refreshing of the access token.
  • InitiateOAuth: Set this to REFRESH.

Option 2: Transfer OAuth Settings

Follow the steps below to install the connector on another machine, authenticate, and then transfer the resulting OAuth values.

On a second machine, install the connector and connect with the following properties set:

  • OAuthSettingsLocation: Set this to a writable location.
  • InitiateOAuth: Set this to GETANDREFRESH.
  • OAuthClientId: Set this to the Client ID in your application settings.
  • OAuthClientSecret: Set this to the Client Secret in your application settings.
  • CallbackURL: Set this to the Callback URL in your application settings.

Test the connection to authenticate. The resulting authentication values are written, encrypted, to the location specified by OAuthSettingsLocation. After you have successfully tested the connection, copy the OAuth settings file to your headless machine. On the headless machine, set the following connection properties to connect to data:

  • InitiateOAuth: Set this to REFRESH.
  • OAuthSettingsLocation: Set this to the location of your OAuth settings file. Make sure this location gives read and write permissions to the connector to enable the automatic refreshing of the access token.
OAuthPKCE

NOTE:OAuth Proof Key for Code Exchange (PKCE) is an extension to the OAuth 2.0 Authorization Code flow.

Desktop Applications

After setting the following, you are ready to connect:

  • AuthScheme: Set this to OAuthPKCE.
  • InitiateOAuth: Set this to GETANDREFRESH to avoid making the OAuth exchange manually and manually setting the access token in the connection string.
  • OAuthClientId: Set this to the client ID generated when creating your OAuth application on the GraphQL service.
  • OAuthAuthorizationURL: Set this to the authorization URL for the GraphQL service. This is the URL where the user logs into the service and grants permissions to the OAuth application, for example https://api.example.com/authorize.
  • OAuthAccessTokenURL: Set this to the access token URL for the GraphQL service. This is the URL where the request for the access token is made, for example https://api.example.com/token.
  • OAuthRefreshTokenURL: Set this to the refresh token URL for the GraphQL service. This is the URL where the refresh token is exchanged for a new access token when the old one expires. Note that for your data source this may be the same as the OAuthAccessTokenURL.

When you connect, the connector opens the OAuth authorization endpoint in your default browser. Log in and grant permissions to the application. The connector then completes the OAuth process:

  1. Extracts the authorization code from the callback URL.
  2. Exchanges the authorization code for an access and refresh token.
  3. Refreshes the access token when it expires.
  4. Saves OAuth values in OAuthSettingsLocation. These values persist across connections.

AWS Cognito Credentials

If you want to use the connector with a user registered in a User Pool in AWS Cognito, set the following properties to authenticate:

  • AuthScheme: Set this to AwsCognitoSrp (recommended). You can also use AwsCognitoBasic.
  • AWSCognitoRegion: Set this to the region of the User Pool.
  • AWSUserPoolId: Set this to the User Pool Id.
  • AWSUserPoolClientAppId: Set this to the User Pool Client App Id.
  • AWSUserPoolClientAppSecret: Set this to the User Pool Client Secret.
  • AWSIdentityPoolId: Set this to the Identity Pool ID of the Identity Pool that is linked with the User Pool.
  • User: Set this to the username of the user registered in the User Pool.
  • Password: Set this to the password of the user registered in the User Pool.

Important Notes

Configuration Files and Their Paths

  • All references to adding configuration files and their paths refer to files and locations on the Jitterbit agent where the connector is installed. These paths are to be adjusted as appropriate depending on the agent and the operating system. If multiple agents are used in an agent group, identical files will be required on each agent.

Model GraphQL Data

This section shows how to control the various schemas that the connector offers to bridge the gap between relational SQL and GraphQL services.

Schema Introspection

GraphQL services offer a introspection query service which the connector can use to obtain view and column names.

All SCALAR mutation fields are exposed directly, and all object fields are expanded.

Mutations

The connector will automatically scan for available Using Mutations. Given that there is no method provided by GraphQL for determining which mutations can be used for each table, each mutation is exposed as a stored procedure.

LIST fields are exposed as temporary tables (GraphQL tables of type TEMPORARY_TABLE). The discovered temporary tables can be obtained by querying the sys_tables and sys_tablecolumns system tables.

Customize Schemas

Operations details the process for configuring custom schema files. Setting up these custom schema files is a required step in establishing a connection to GraphQL data.

System Tables

See System Tables to query the current table metadata.

Stored Procedures

The connector makes use of Stored Procedures to perform various functions, such as obtaining and refreshing OAuth tokens.

Automatic Schema Discovery

By default, the connector will automatically read metadata from GraphQL.

Schema Introspection

GraphQL services offer a introspection query service which the connector can use to obtain view and column names.

A GraphQL introspection query service has a query object at its root. Other objects are nested into the root query object, which can in turn have their own nested objects.

The connector reads LIST or Relay Connection type objects as views. If a field is SCALAR, it's read as a column, and if a field is a simple OBJECT, it is expanded.

Set the metadata introspection depth as follows:

  • ExpandTablesDepth: Setting to 0 will read only from the root query object. In scenarios where lists are nested in other lists, set the ExpandTablesDepth to the number of nested layers deep to be scanned.
  • ExpandColumnsDepth: This determines how many more layers deep (starting from the ExpandTablesDepth) to expand objects to include fields from their nested child objects.

Use Mutations

The connector will automatically scan for available mutations. Given that there is no method provided by GraphQL for determining which mutations can be used for each table, each mutation is exposed as a stored procedure.

All SCALAR mutation fields are exposed directly, and all object fields are expanded.

LIST fields are exposed as temporary tables (GraphQL tables of type TEMPORARY_TABLE). The discovered temporary tables can be obtained by querying the sys_tables and sys_tablecolumns system tables. These tables contain a RowId and ParentId field to denote the row and housing (parent) table of a given child table.

An example of a mutation is productCreate. Invoke mutations as a stored procedure after first loading the relevant child tables needed for the operation:

INSERT INTO productCreate_metafields (namespace,key,value,type) VALUES ('MRproductInfo','ALU','449788022','string')

INSERT INTO productCreate_variants (RowId,price,sku,inventoryManagement,weightUnit,weight,options,metafields,inventoryQuantities) VALUES (1,'39.99','38536314-0acb-4d3f-b8ff-a0f2014d2c75','SHOPIFY','POUNDS',1,'L,XL,XXL','productCreate_variants_metafields','productCreate_variants_inventoryQuantities')

INSERT INTO productCreate_variants_metafields (ParentId,namespace,key,value,type) VALUES ('1','MRproductInfo','ALU','449788022-M-','string')

INSERT INTO productCreate_variants_metafields (ParentId,namespace,key,value,type) VALUES ('1','MRproductInfo','ItemNumber','400000881201','string')

INSERT INTO productCreate_variants_inventoryQuantities (ParentId,locationId,availableQuantity) VALUES ('1','gid://shopify/Location/1448280087',5)

INSERT INTO productCreate_media (originalSource,alt,mediaContentType) VALUES ('https://static.nike.com/a/images/t_PDP_1280_v1/f_auto,q_auto:eco/qwqfyddzikcgc4ozwigp/revolution-5-road-running-shoes-szF7CS.png','Magic Shoes','IMAGE')

EXECUTE productCreate title='NIKE  - 449788022', descriptionHtml=' - MEN\'S SHOES  42-MENS L/S TEES',productType='Staging', vendor='NIKE', published='false', options='size,width',metafields='productCreate_metafields', variants='productCreate_variants', media='productCreate_media'

Customize Schemas

Custom schemas are defined in configuration files. This chapter outlines the structure of these files.
Note: The GenerateSchemaFiles property enables you to persist table metadata in static schema files that are easy to customize (to persist your changes to column data types, for example). Set this property to "OnStart" to generate schema files for all tables in your database at connection. Alternatively, set this property to "OnUse" to generate schemas as you execute SELECT queries to tables. It is also possible to create a specific schema file for a table using the CreateSchema stored procedure.

Edit Schema Files

Tables and views are defined by authoring schema files in APIScript. APIScript is a simple configuration language that allows you to define the columns and the behavior of the table. It also has built-in Operations that enable you to process GraphQL. In addition to these data processing primitives, APIScript is a full-featured language with constructs for conditionals, looping, etc. However, as shown by the example schema, for most table definitions you will not need to use these features.

Example Schema

Below is a fully functional table schema that models the Labels table and contains all the components you will need to execute SQL to GraphQL data sources.

You can find more information on each of the components of a schema in Column Definitions, SELECT Execution.

Example Custom Headers

Static Headers

The following example shows how to add static headers in the schema file. These headers are added to the request every time the schema file is called.

<rsb:script xmlns:rsb="http://apiscript.com/ns?v1" xmlns:xs="http://www.cdata.com/ns/rsbscript/2" xmlns:other="http://apiscript.com/ns?v1">
...
<input name="Ship1" other:headerName="DynamicValuedHeader" />
<input name="Ship2" other:headerName="DynamicValuedHeader" />
</rsb:info>

<api:set attr="Header:Name#1"  value="StaticValuedHeader" />
<api:set attr="Header:Value#1" value="StaticValuedHeader__Value" />
Dynamic Headers

The following example shows how to add dynamic headers in the schema file. These headers are added to the request every time the schema file is called.

<rsb:script xmlns:rsb="http://apiscript.com/ns?v1" xmlns:xs="http://www.cdata.com/ns/rsbscript/2" xmlns:other="http://apiscript.com/ns?v1">
...
<input name="Ship1" other:headerName="DynamicValuedHeader" />
<input name="Ship2" other:headerName="DynamicValuedHeader" />
<input name="Ship3" other:headerName="DynamicValuedHeader2" />
</rsb:info>

<api:set attr="Header:Name#1"  value="DynamicValuedHeader" />
<api:set attr="Header:Value#1" value="[_input.Ship1] - [_input.Ship2]" />
SELECT * FROM [Table] WHERE [Ship1] = "Value1" AND [Ship2] = "Value2" AND [DynamicValuedHeader2] = "custom value"

In the above example, the value format of DynamicValuedHeader is parsed by the driver, but for DynamicValuedHeader2, it is the same as the value specified in the query.

Column Definitions

The basic attributes of a column are the name of the column, the data type, whether the column is a primary key, the relative path and the depth. The connector uses the depth attribute to extract nodes from hierarchical data.

Mark up column attributes in the block of the schema file. You can also provide a description of each attribute using the desc property.

The following sections provide more detail on using paths to extract columns and rows. To see the column definitions in a complete schema, refer to Customizing Schemas.

Map SELECT Projection to GraphQL Fields

Control the building process of a GraphQL field path with the properties listed below:

  1. The other:possiblePaths property is used to specify the base paths that select the column's value.

    Base paths start with a '/' and contain the full path to the last GraphQL nested object.

      <rsb:info title="Labels" desc="Lists information about the different labels you can apply to an issue." other:possiblePaths="{'path':'/repository/labels/edges/node','Name':{'path':'/repository/label'}}" other:paginationObjects="{'labels':{'cursorPath':'after','cursorType':'String','pageSizeArgumentPath':'first','pageSizeArgumentType':'Int','depth':'1''paginationType':'Cursor','isConnection':'True','pageInfo':['endCursor','hasNextPage','hasPreviousPage','startCursor']}}">
    

    The following GraphQL query is based on the above script example:

    { # base path=/repository/labels/edges/node
      repository {
        labels {
          edges {
            node {
              ...
            }
          }
        }
      }
    }
    
  2. The other:relativePath property must be specified for each column. This property is used in conjuction with the other:possiblePaths property to build the GraphQL field path.

      <attr   name="Name"  xs:type="string"  other:relativePath="name"  desc="Identifies the label name."    />
    

    Based on the above script example the connector will build the following GraphQL query:

    { # base path=/repository/labels/edges/node
      repository { # depth=1
        labels { # depth=2
          edges {
            node {
              name # path=base path + relative path.
            }
          }
        }
      }
    }
    
  3. Use the other:depth property to specify an element inside a specific GraphQL object. The indexes are 1-based. If this attribute is not specified then the default value will be equal to the last nested GraphQL object.

      <attr   name="RepositoryName"   xs:type="string"  other:relativePath="name"   desc="The name of the repository."  other:depth="1" />
    

    The following GraphQL query is built from the above script example:

    { # base path=/repository/labels/edges/node
      repository { # depth=1
        name # This is mapped to the RepositoryName column
        labels { # depth=2
          edges {
            node {
              ...
            }
          }
        }
      }
    }
    
  4. Use the other:fragment property to specify a group of fields. This property can be used when the GraphQL server returns an array of objects and the connector may need to push this info as an aggregate.

      <attr   name="ColumnValues"   xs:type="string"  other:relativePath="column_values"   desc="Column values."  other:fragment="fragment ItemColumnValues on ColumnValue {  ID \r\n value }" />
    

    Based on the above script example, the connector will build the following GraphQL query:

    query {
        items {
            column_values {
                ...ItemColumnValues
            }
        }
    }
    fragment ItemColumnValues on ColumnValue {
        id
        value
    }
    
  5. Use the other:canbesliced property enable slicing behavior in the connector

    For example,

    SELECT * FROM Table WHERE Col IN ('1','2','3')
    

    becomes

    SELECT * FROM Table WHERE Col=1
    SELECT * FROM Table WHERE Col=2
    SELECT * FROM Table WHERE Col=3
    
  6. Use the other:mirror property to reflect the value specified in the criteria. Use on columns that are not specified in the server response.

    For example:

    SELECT * FROM Table WHERE Col=X (If other:mirror=true the connector will artificially set the value of Col to X for every row.)
    
  7. Use references to reference the key column of the parent table. Example: If there are two tables Orders and OrderLineItems and the OrderLineItems has a column OrderId, the references field for this column will be "Orders.Id".

Note

  • Paths and column names (when used to generate the path) are case sensitive.
  • At least one possible path should be specified.
  • The other:relativePath property must be specified for every column. Otherwise, the connector cannot map the SELECT column to a GraphQL field.

SELECT Execution

When a SELECT query is issued, the connector executes the GET method of the schema, which invokes the connector's built-in operations to process GraphQL. In the GET method you have control over the request for data. The following procedures show several ways to use this: search the remote data, server-side, with SELECT WHERE, or implement paging.

Map SELECT criteria to GraphQL arguments

The following sections show how to translate a SELECT WHERE statement into a GraphQL query to GraphQL APIs. The procedure uses the following statement:

SELECT *
FROM <table>
WHERE ModifiedAt<'2019-10-30 05:05:36.001'

If this filter is supported on the server via query parameters, you can use the other:filter property of the api:info column definition to specify the desired mapping. For the above query, the connector will use this property to map the modifiedAt < '<date>' filter to the query parameter that returns results that were modifed before a given date, and the modifedAt > '<date>' filter to the query parameter that filters results that were modifed after.

  • other:filter is a semicolon separated list of <parameter name>:<operator list>. <parameter name> is the name of the query parameter and <operator list> is a comma-separated list of operators used for the mapping. Valid operators are <, <=, =, > and >=.
  • other:argumentType is a required extra info. It should contain the type of the argument based on the GraphQL schema type language.

To perform this mapping, the connector would use the following markup for the modifedAt column definition:

<attr name="ModifiedAt" xs:type="datetime" other:relativePath="modifiedAt" other:argumentType="DateTime" description="When the vendor was last modified." other:filter="modifiedAtAfter:>;modifiedAtBefore:<" />

This query results in the following postdata:

{
    "variables": {
        "ModifiedAt_modifiedAtBefore": "2019-10-30T09:05:36.001Z"
    },
    "query": "query($ModifiedAt_modifiedAtBefore:DateTime) {\r\nbusinesses {\r\nedges {\r\nnode {\r\ncustomers(modifiedAtBefore:$ModifiedAt_modifiedAtBefore) {\r\nedges {\r\nnode {\r\nid\r\nmodifiedAt\r\n}\r\n}\r\npageInfo {\r\ntotalPages\r\ncurrentPage\r\n}\r\n}\r\nid\r\n}\r\n}\r\npageInfo {\r\ntotalPages\r\ncurrentPage\r\n}\r\n}\r\n}\r\n"
}
Path filters

There exist GraphQL services where the GraphQL argument is not enough to process the filter servereport suite ID (RSID)e. The path should be changed. In order to correctly use a path filter you need to complete the following steps:

  1. Add the path to the other:possiblePaths extra info and map it with the column name you want to filter.

    Ex: other:possiblepaths="{'path':'/businesses/edges/node','id':{'path':'/business'}}"

  2. Set the other:isPathFilter to TRUE in the column defintion.

    <attr  name="Id"  xs:type="string" key="true" other:relativePath="id" other:isPathFilter="true" other:filter="id:="  />
    

After completing these steps the following SQL query

SELECT Id,Name,CreatedAt FROM Businesses WHERE Id='QnVzaW5M6ZTY4ZDA2MmQtYzkzZS00MGZkLTk4YWUtNDg2YzcxMmExNzFl'

will be converted to the postdata:

{
    "variables": {
        "Id_id": "QnVzaW5M6ZTY4ZDA2MmQtYzkzZS00MGZkLTk4YWUtNDg2YzcxMmExNzFl"
    },
    "query": "query($Id_id:ID) {\r\nbusiness(id:$Id_id) {\r\nid\r\nname\r\ncreatedAt\r\n}\r\n}\r\n"
}
Pagination

The driver supports two pagination modes.

  • Cursor

    other:paginationObjects = "{
        'labels': {
            'cursorPath': 'after',
            'cursorType': 'String',
            'pageSizeArgumentPath': 'first',
            'pageSizeArgumentType': 'Int',
        'depth':'1',
            'paginationType': 'Cursor',
            'isConnection': 'True',
            'pageInfo': ['endCursor', 'hasNextPage', 'hasPreviousPage', 'startCursor']
        }
    }"
    

    The following postdata will be generated after processing the other:paginationObjects table extra info specified above:

    {
        "variables": {
            "UserLogin_owner": "testaccount71",
            "RepositoryName_name": "test",
            "first": <Pagesize>
        },
        "query": "query($UserLogin_owner:String!, $RepositoryName_name:String!, $first:Int) {\r\nrepository(owner:$UserLogin_owner, name:$RepositoryName_name) {\r\nlabels(first:$first) {\r\nedges {\r\nnode {\r\nid\r\ncolor\r\ncreatedAt\r\ndescription\r\nisDefault\r\nname\r\nresourcePath\r\nupdatedAt\r\nurl\r\n}\r\n}\r\npageInfo {\r\nendCursor\r\nhasNextPage\r\n}\r\n}\r\nname\r\n}\r\n}\r\n"
    }
    
  • Offset

    other:paginationObjects="{
        'businesses': {
            'offsetArgumentPath': 'page',
            'offsetArgumentType': 'Int',
            'pageSizeArgumentPath': 'pageSize',
            'pageSizeArgumentType': 'Int',
        'depth':'1',
            'paginationType': 'Offset',
            'isConnectionObject': 'True',
            'pageInfo': ['currentPage', 'totalPages', 'totalCount']
        }
    }"
    

    The following postdata will be generated after processing the other:paginationObjects table extra info specified above:

    {
        "variables": {
            "pageSize_1": <Pagesize>
        },
        "query": "query($pageSize_1:Int) {\r\nbusinesses(pageSize:$pageSize_1) {\r\nedges {\r\nnode {\r\nid\r\n}\r\n}\r\npageInfo {\r\ntotalPages\r\ncurrentPage\r\n}\r\n}\r\n}\r\n"
    }
    

Note

The driver supports pagination with input objects as arguments.

other:paginationObjects="{
    'businesses': {
        'offsetArgumentPath': 'query/pagination/page',
        'offsetArgumentType': 'custom_query',
        'pageSizeArgumentPath': 'query/pagination/pageSize',
        'pageSizeArgumentType': 'custom_query',
        'depth':'1',
        'paginationType': 'Offset',
        'isConnectionObject': 'True',
        'pageInfo': ['currentPage', 'totalPages', 'totalCount']
    }
}"

The following postdata will be generated after processing the other:paginationObjects table extra info specified above:

{
    "variables": {
        "query": {
            "pagination": {
                "pageSize":<Pagesize>
            }
        }
    },
    "query": "query($query:custom_query) {\r\nbusinesses(query:$query) {\r\nedges {\r\nnode {\r\nid\r\n}\r\n}\r\npageInfo {\r\ntotalPages\r\ncurrentPage\r\n}\r\n}\r\n}\r\n"
}
Process Other SELECT Statements Server Side
ORDER BY

You can sort the results servereport suite ID (RSID)e if the GraphQL service supports it by specifying the following properties:

  • The other:orderByFormat can be specified in the table definition or in the column definition.

    <rsb:info title="Labels" desc="Lists information about the different labels you can apply on an issue." other:orderByFormat="{field: {orderByArgumentValue}, direction: {sortOrder}}">
    <attr name="CreatedAt" xs:type="datetime" other:relativePath="createdAt"  other:orderByFormat="{field: {orderByArgumentValue}, direction: {sortOrder}}" other:orderBy="orderBy:CREATED_AT" />
    
  • The other:orderBy should be specified only in the column definition. The format of this property is <orderByArgumentName>:<orderByArgumentValue>

    <attr name="CreatedAt" xs:type="datetime" other:relativePath="createdAt"  other:orderBy="orderBy:CREATED_AT" />
    

After completing these steps the following SQL query

SELECT ID FROM Labels ORDER BY CreatedAt ASC

will be converted to the postdata:

{
    "variables": {

Operations

The connector has high-performance operations for processing GraphQL data sources. These operations are platform neutral: Schema files that invoke these operations can be used in both .NET and Java. You can also extend the connector with your own operations written in .NET or Java.

The connector has the following operations:

Operation Name Description
OAuthGetAccessToken For OAuth 1.0, exchange a request token for an access token. For OAuth 2.0, get an access token or get a new access token with the refresh token.
OAuthGetUserAuthorizationURL Generates the user authorization URL. OAuth 2.0 will not access the network in this operation.
OAuthGetAccessToken

The OAuthGetAccessToken operation is an APIScript operation that is used to facilitate the OAuth authentication and refresh flows.

The connector includes stored procedures that invoke this operation to complete the OAuth exchange. The following example schema briefly lists some of the typically required inputs before the following sections explain them in more detail.

Create a GetOAuthAccessToken Stored Procedure

Invoke the OAuthGetAccessToken with the GetOAuthAccessToken stored procedure. The following inputs are required for most data sources and will provide default values for the connection properties of the same name.

Stored Procedures

Stored procedures are function-like interfaces that extend the functionality of the connector beyond simple SELECT operations with GraphQL.

Stored procedures accept a list of parameters, perform their intended function, and then return any relevant response data from GraphQL, along with an indication of whether the procedure succeeded or failed.

Jitterbit Connector for GraphQL Stored Procedures

Name Description
CreateSchema Creates a schema file for the specified table or view.
GetOAuthAccessToken Obtains the OAuth access token to be used for authentication with data sources using OAuth.
GetOAuthAuthorizationURL Obtains the OAuth authorization URL used for authentication with data sources using OAuth.
RefreshOAuthAccessToken Exchanges a refresh token for a new access token.

CreateSchema

Creates a schema file for the specified table or view.

CreateSchema

Creates a local schema file (.rsd) from an existing table or view in the data model.

The schema file is created in the directory set in the Location connection property when this procedure is executed. You can edit the file to include or exclude columns, rename columns, or adjust column datatypes.

The connector checks the Location to determine if the names of any .rsd files match a table or view in the data model. If there is a duplicate, the schema file will take precedence over the default instance of this table in the data model. If a schema file is present in Location that does not match an existing table or view, a new table or view entry is added to the data model of the connector.

Input
Name Type Description
TableName String The name of the table or view.
FileName String The full file path and name of the schema to generate. Ex : 'C:\Users\User\Desktop\GraphQL\Businesses.rsd'

OAuthSettingsLocation

The location of the settings file where OAuth values are saved when InitiateOAuth is set to GETANDREFRESH or REFRESH. Alternatively, you can hold this location in memory by specifying a value starting with 'memory://'.

Data Type

string

Default Value

%APPDATA%\CData\Acumatica Data Provider\OAuthSettings.txt

Remarks

When InitiateOAuth is set to GETANDREFRESH or REFRESH, the driver saves OAuth values to avoid requiring the user to manually enter OAuth connection properties and to allow the credentials to be shared across connections or processes.

Instead of specifying a file path, you can use memory storage. Memory locations are specified by using a value starting with 'memory://' followed by a unique identifier for that set of credentials (for example, memory://user1). The identifier can be anything you choose but should be unique to the user. Unlike file-based storage, where credentials persist across connections, memory storage loads the credentials into static memory, and the credentials are shared between connections using the same identifier for the life of the process. To persist credentials outside the current process, you must manually store the credentials prior to closing the connection. This enables you to set them in the connection when the process is started again. You can retrieve OAuth property values with a query to the sys_connection_props system table. If there are multiple connections using the same credentials, the properties are read from the previously closed connection.

The default location is "%APPDATA%\CData\Acumatica Data Provider\OAuthSettings.txt" with %APPDATA% set to the user's configuration directory. The default values are

  • Windows: "register://%DSN"
  • Unix: "%AppData%..."

where DSN is the name of the current DSN used in the open connection.

The following table lists the value of %APPDATA% by OS:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Linux ~/.config

CallbackURL

The grant type for the OAuth flow.

Possible Values

CODE, CLIENT, PASSWORD

Data Type

string

Default Value

CLIENT

Remarks

The following options are available: CODE,CLIENT,PASSWORD

OAuthIncludeCallbackURL

Whether to include the callback URL in an access token request.

Data Type

bool

Default Value

true

Remarks

This defaults to true since standards-compliant OAuth services will ignore the redirect_uri parameter for grant types like CLIENT or PASSWORD that do not require it.

This option should only be enabled for OAuth services that report errors when redirect_uri is included.

OAuthAuthorizationURL

The authorization URL for the OAuth service.

Data Type

string

Default Value

If using a TLS/SSL connection, this property can be used to specify the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected.

This property can take the following forms:

Description Example
A full PEM Certificate (example shortened for brevity) -----BEGIN CERTIFICATE----- MIIChTCCAe4CAQAwDQYJKoZIhv......Qw== -----END CERTIFICATE-----
A path to a local file containing the certificate C:\\cert.cer
The public key (example shortened for brevity) -----BEGIN RSA PUBLIC KEY----- MIGfMA0GCSq......AQAB -----END RSA PUBLIC KEY-----
The MD5 Thumbprint (hex values can also be either space or colon separated) ecadbdda5a1529c58a1e9e09828d70e4

If not specified, any certificate trusted by the machine is accepted.

Certificates are validated as trusted by the machine based on the System's trust store. The trust store used is the 'javax.net.ssl.trustStore' value specified for the system. If no value is specified for this property, Java's default trust store is used (for example, JAVA_HOME\lib\security\cacerts).

Use '*' to signify to accept all certificates. Note that this is not recommended due to security concerns.

Schema

This section provides a complete list of schema properties you can configure.

Property Description
Location A path to the directory that contains the schema files defining tables, views, and stored procedures.
BrowsableSchemas This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA, SchemaB, SchemaC.
Tables This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA, TableB, TableC.
Views Restricts the views reported to a subset of the available tables. For example, Views=ViewA, ViewB, ViewC.
ExpandArgumentsDepth This property is used to determine how far the provider should search for columns inside the arguments of type INPUT_OBJECT.
ExpandTablesDepth This property is used to determine the depth of the child tables.
ExpandTemporaryTablesDepth This property is used to determine the depth of the child temporary tables. Only works if ExposeDynamicProcedures is set to true.
ExpandColumnsDepth This property is used to determine how far the provider should search for columns inside the GraphQL objects.
IncludeDeprecatedMetadata This property is used to determine whether the provider should expose deprecated tables and columns or not.
ExposeDynamicProcedures This property is used to determine whether the provider should expose mutations as dynamic procedures or not.
ExposeObjectTables This property is used to determine the extent to which the provider exposes GraphQL object type fields as tables.

Location

A path to the directory that contains the schema files defining tables, views, and stored procedures.

Data Type

string

Default Value

%APPDATA%\GraphQL Data Provider\Schema

Remarks

The path to a directory which contains the schema files for the connector (.rsd files for tables and views, .rsb files for stored procedures). The folder location can be a relative path from the location of the executable. The Location property is only needed if you want to customize definitions (for example, change a column name, ignore a column, and so on) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is "%APPDATA%\GraphQL Data Provider\Schema" with %APPDATA% being set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Mac ~/Library/Application Support
Linux ~/.config

BrowsableSchemas

This property restricts the schemas reported to a subset of the available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC.

Data Type

string

Default Value

""

Remarks

Listing the schemas from databases can be expensive. Providing a list of schemas in the connection string improves the performance.

Tables

This property restricts the tables reported to a subset of the available tables. For example, Tables=TableA,TableB,TableC.

Data Type

string

Default Value

""

Remarks

Listing the tables from some databases can be expensive. Providing a list of tables in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

Views

Restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC.

Data Type

string

Default Value

""

Remarks

Listing the views from some databases can be expensive. Providing a list of views in the connection string improves the performance of the connector.

This property can also be used as an alternative to automatically listing views if you already know which ones you want to work with and there would otherwise be too many to work with.

Specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note that when connecting to a data source with multiple schemas or catalogs, you will need to provide the fully qualified name of the table in this property, as in the last example here, to avoid ambiguity between tables that exist in multiple catalogs or schemas.

ExpandArgumentsDepth

This property is used to determine how far the provider should search for columns inside the arguments of type INPUT_OBJECT.

Data Type

int

Default Value

2

Remarks

This property is used to determine how far the connector should search for columns inside the arguments of type INPUT_OBJECT. For example:

{
    "variables": {
        "input": {
            "filters": {
                "type": "SUPPLIER"
            }
        }
    },
    "query": "query($input:FilteredCompaniesInput!) {\r\nfilteredCompanies(input:$input) {\r\nid:id\r\nvalue:value\r\n}\r\n}\r\n"
}

for the SQL query:

SELECT id,value FROM filteredCompanies WHERE type='SUPPLIER'

In this case the nested "FilteredCompaniesInput" is itself of type INPUT_OBJECT.&nbps;In a column search, the ExpandColumnsDepth property controls how many nested levels of type INPUT_OBJECT are subjected to searching.

ExpandTablesDepth

This property is used to determine the depth of the child tables.

Data Type

int

Default Value

2

Remarks

This property is used to determine the depth of the child tables.

ExpandTemporaryTablesDepth

This property is used to determine the depth of the child temporary tables. Only works if ExposeDynamicProcedures is set to true.

int

Default Value

5

Remarks

This property is used to determine the depth of the child temporary tables. Only works if ExposeDynamicProcedures is set to true.

ExpandColumnsDepth

This property is used to determine how far the provider should search for columns inside the GraphQL objects.

Data Type

int

Default Value

2

Remarks

This property is used to determine how far the connector should search for columns inside the GraphQL objects.

IncludeDeprecatedMetadata

This property is used to determine whether the provider should expose deprecated tables and columns or not.

Data Type

bool

Default Value

false

Remarks

This property is used to determine whether the connector should expose deprecated tables and columns or not.

ExposeDynamicProcedures

This property is used to determine whether the provider should expose mutations as dynamic procedures or not.

Data Type

bool

Default Value

true

Remarks

This property is used to determine whether the connector should expose mutations as dynamic procedures or not.

Miscellaneous

This section provides a complete list of miscellaneous properties you can configure.

Property Description
CustomHeaders Other headers as determined by the user (optional).
GenerateSchemaFiles Indicates the user preference as to when schemas should be generated and saved.
MaxRows Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.
Other These hidden properties are used only in specific use cases.
Pagesize The maximum number of results to return per page from GraphQL.
PseudoColumns This property indicates whether or not to include pseudo columns as columns to the table.
Timeout The value in seconds until the timeout error is thrown, canceling the operation.
UserDefinedViews A filepath pointing to the JSON configuration file containing your custom views.

CustomHeaders

Other headers as determined by the user (optional).

Data Type

string

Default Value

""

Remarks

This property can be set to a string of headers to be appended to the HTTP request headers created from other properties, like ContentType, From, and so on.

The headers must be of the format "header: value" as described in the HTTP specifications. Header lines should be separated by the carriage return and line feed (CRLF) characters.

Use this property with caution. If this property contains invalid headers, HTTP requests may fail.

This property is useful for fine-tuning the functionality of the connector to integrate with specialized or nonstandard APIs.

GenerateSchemaFiles

Indicates the user preference as to when schemas should be generated and saved.

Possible Values

Never, OnUse, OnStart, OnCreate

Data Type

string

Default Value

Never

Remarks

This property outputs schemas to .rsd files in the path specified by Location.

Available settings are the following:

  • Never: A schema file will never be generated.
  • OnUse: A schema file will be generated the first time a table is referenced, provided the schema file for the table does not already exist.
  • OnStart: A schema file will be generated at connection time for any tables that do not currently have a schema file.
  • OnCreate: A schema file will be generated by when running a CREATE TABLE SQL query.

Note that if you want to regenerate a file, you will first need to delete it.

Generate Schemas with SQL

When you set GenerateSchemaFiles to OnUse, the connector generates schemas as you execute SELECT queries. Schemas are generated for each table referenced in the query.

When you set GenerateSchemaFiles to OnCreate, schemas are only generated when a CREATE TABLE query is executed.

Generate Schemas on Connection

Another way to use this property is to obtain schemas for every table in your database when you connect. To do so, set GenerateSchemaFiles to OnStart and connect.

MaxRows

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

Data Type

int

Default Value

-1

Remarks

Limits the number of rows returned when no aggregation or GROUP BY is used in the query. This takes precedence over LIMIT clauses.

Other

These hidden properties are used only in specific use cases.

Data Type

string

Default Value

""

Remarks

The properties listed below are available for specific use cases. Normal driver use cases and functionality should not require these properties.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting
Property Description
DefaultColumnSize Sets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMT Determines whether to convert date-time values to GMT, instead of the local time of the machine.
RecordToFile=filename Records the underlying socket data transfer to the specified file.

Pagesize

The maximum number of results to return per page from GraphQL.

Data Type

string

Default Value

""

Remarks

The Pagesize property affects the maximum number of results to return per page from GraphQL. Setting a higher value may result in better performance at the cost of additional memory eaten up per page consumed. The pageSize is proportional to the GraphQL query cost.

PseudoColumns

This property indicates whether or not to include pseudo columns as columns to the table.

Data Type

string

Default Value

""

Remarks

This setting is particularly helpful in Entity Framework, which does not allow you to set a value for a pseudo column unless it is a table column. The value of this connection setting is of the format "Table1=Column1, Table1=Column2, Table2=Column3". You can use the "*" character to include all tables and all columns; for example, "*=*".

Timeout

The value in seconds until the timeout error is thrown, canceling the operation.

Data Type

int

Default Value

60

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the connector throws an exception.

UserDefinedViews

A filepath pointing to the JSON configuration file containing your custom views.

Data Type

string

Default Value

""

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The connector automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the connector.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
    "MyView": {
        "query": "SELECT * FROM Users WHERE MyColumn = 'value'"
    },
    "MyView2": {
        "query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
    }
}

Use the UserDefinedViews connection property to specify the location of your JSON configuration file. For example:

"UserDefinedViews", C:\Users\yourusername\Desktop\tmp\UserDefinedViews.json

Note that the specified path is not embedded in quotation marks.
