When making calls to fabric APIs, you must use the following HTTP headers to provide context.
  • --header: This flag is used to include headers in the request. The most commonly used headers in fabric APIs are:
    • x-fabric-tenant-id: This is a custom header used by the API to identify the tenant making the request. You can find the tenant-id in Copilot.
    • Content-Type: application/json: This tells the server that the data being sent in the request is in JSON format.
    • Authorization: Bearer: This is the authorization token used to authenticate the request. You must pass the access token generated from the system app.
    • x-fabric-channel-id: This is a custom header, used to identify the channel through which the request is being made. This is primarily used for a multichannel use case. Usually, the default value is 12 (US).
fabric API responses are in JSON format.
