Hello @Lily-9563,

Thanks for the question and using MS Q&A platform.

You can use the below method to call Azure REST API of Azure API Management:

 URL:https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ApiManagement/service/{serviceName}/subscriptions?api-version=2021-08-01
 Method: GET
 Authentication: System Assigned Managed Identity
 Resource: https://management.azure.com/

In case if you see this error message: {"error":{"code":"AuthorizationFailed","message":"The client '2bxx-cxx9-4xx3-bxx-8xxxxxx9f4' with object id '2bxx-cxx9-4xx3-bxx-8xxxxxx9f' does not have authorization to perform action 'Microsoft.ApiManagement/service/subscriptions/read' over scope '/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.ApiManagement/service/{serviceName}’ or the scope is invalid. If access was recently granted, please refresh your credentials."}}

Make sure to grant reader permissions for the ADF as shown below:

Here is the complete walkthrough on using Azure Data Factory to call Azure REST API of Azure API Management.

Hope this will help. Please let us know if any further queries.
