This article outlines how to use Copy Activity in an Azure Data Factory or Synapse Analytics pipeline to copy data from an OData source. The article builds on Copy Activity, which presents a general overview of Copy Activity.

Supported capabilities

This OData connector is supported for the following capabilities:

Supported capabilities IR
Copy activity (source/-) ① ②
Lookup activity ① ②

① Azure integration runtime ② Self-hosted integration runtime

For a list of data stores that are supported as sources/sinks, see Supported data stores.

Specifically, this OData connector supports:

  • OData version 2.0, 3.0, and 4.0.
  • Copying data by using one of the following authentications: Anonymous, Basic, Windows, and Microsoft Entra service principal.

Prerequisites

If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.

If your data store is a managed cloud data service, you can use the Azure Integration Runtime. If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list.

You can also use the managed virtual network integration runtime feature in Azure Data Factory to access the on-premises network without installing and configuring a self-hosted integration runtime.

For more information about the network security mechanisms and options supported by Data Factory, see Data access strategies.

Get started

To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:

Create a linked service to an OData store using UI

Use the following steps to create a linked service to an OData store in the Azure portal UI.

  1. Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then select New:

  2. Search for OData and select the OData connector.

    Screenshot of the OData connector.

  3. Configure the service details, test the connection, and create the new linked service.

    Screenshot of linked service configuration for an OData store.

Connector configuration details

The following sections provide details about properties you can use to define Data Factory entities that are specific to an OData connector.

Dataset properties

This section provides a list of properties that the OData dataset supports.

For a full list of sections and properties that are available for defining datasets, see Datasets and linked services.

To copy data from OData, set the type property of the dataset to ODataResource. The following properties are supported:

Property Description Required
type The type property of the dataset must be set to ODataResource. Yes
path The path to the OData resource. Yes

Example

{
    "name": "ODataDataset",
    "properties":
    {
        "type": "ODataResource",
        "schema": [],
        "linkedServiceName": {
            "referenceName": "<OData linked service name>",

        },
        "typeProperties":
        {
            "path": "Products"
        }
    }
}

Copy Activity properties

This section provides a list of properties that the OData source supports.

For a full list of sections and properties that are available for defining activities, see Pipelines.

OData as source

To copy data from OData, the following properties are supported in the Copy Activity source section:

Property Description Required
type The type property of the Copy Activity source must be set to ODataSource. Yes
query OData query options for filtering data. Example: "$select=Name,Description&$top=5".

Note: The OData connector copies data from the combined URL: [URL specified in linked service]/[path specified in dataset]?[query specified in copy activity source]. For more information, see OData URL components.		 No
httpRequestTimeout The timeout (the TimeSpan value) for the HTTP request to get a response. This value is the timeout to get a response, not the timeout to read response data. If not specified, the default value is 00:30:00 (30 minutes). No

Example

"activities":[
    {
        "name": "CopyFromOData",
        "type": "Copy",
        "inputs": [
            {
                "referenceName": "<OData input dataset name>",
                "type": "DatasetReference"
            }
        ],
        "outputs": [
            {
                "referenceName": "<output dataset name>",
                "type": "DatasetReference"
            }
        ],
        "typeProperties": {
            "source": {
                "type": "ODataSource",
                "query": "$select=Name,Description&$top=5"
            },
            "sink": {
                "type": "<sink type>"
            }
        }
    }
]

If you were using RelationalSource typed source, it is still supported as-is, while you are suggested to use the new one going forward.

Data type mapping for OData

When you copy data from OData, the following mappings are used between OData data types and interim data types used within the service internally. To learn how Copy Activity maps the source schema and data type to the sink, see Schema and data type mappings.

OData data type Interim service data type
Edm.Binary Byte[]
Edm.Boolean Bool
Edm.Byte Byte[]
Edm.DateTime DateTime
Edm.Decimal Decimal
Edm.Double Double
Edm.Single Single
Edm.Guid Guid
Edm.Int16 Int16
Edm.Int32 Int32
Edm.Int64 Int64
Edm.SByte Int16
Edm.String String
Edm.Time TimeSpan
Edm.DateTimeOffset DateTimeOffset

Note

OData complex data types (such as Object) aren't supported.

Copy data from Project Online

Project Online requires user-based OAuth, which is not supported by Azure Data Factory. To copy data from Project Online, you can use the OData connector and an access token obtained from tools like Postman.

Caution

The access token expires in 1 hour by default, you need to get a new access token when it expires.

  1. Use Postman to get the access token:

    Note

    Postman is a used by some developers for testing remote web APIs. However, there are some security and privacy risks associated with its usage. This article does not endorse the use of Postman for production environments. Please use it at your own risk.

    1. Navigate to Authorization tab on the Postman Website.
    2. In the Type box, select OAuth 2.0, and in the Add authorization data to box, select Request Headers.
    3. Fill the following information in the Configure New Token page to get a new access token:
      • Grant type: Select Authorization Code.
      • Callback URL: Enter https://www.localhost.com/.
      • Auth URL: Enter https://login.microsoftonline.com/common/oauth2/authorize?resource=https://<your tenant name>.sharepoint.com. Replace <your tenant name> with your own tenant name.
      • Access Token URL: Enter https://login.microsoftonline.com/common/oauth2/token.
      • Client ID: Enter your Microsoft Entra service principal ID.
      • Client Secret: Enter your service principal secret.
      • Client Authentication: Select Send as Basic Auth header.
    4. You will be asked to sign in with your username and password.
    5. Once you get your access token, please copy and save it for the next step.

    Screenshot of using Postman to get the access token.

  2. Create the OData linked service:

    • Service URL: Enter https://<your tenant name>.sharepoint.com/sites/pwa/_api/Projectdata. Replace <your tenant name> with your own tenant name.
    • Authentication type: Select Anonymous.
    • Auth headers:
      • Property name: Choose Authorization.
      • Value: Enter Bearer <access token from step 1>.
    • Test the linked service.

    Create OData linked service

  3. Create the OData dataset:

    1. Create the dataset with the OData linked service created in step 2.
    2. Preview data.

    Preview data
