A connect API client is created using AGC Console Connect API option. When creating the client, a project is selected as well to limit the scope of access. Credentials are created without problem.
Obtained access token by using POST to this AGC URL, then passed the token to publishing API, Connect API server returned 403 error code when using GET method to query the API. Checking the document, there is mention of setting the project to N/A to avoid the error.
My question is why the project could not be set here?
Connect API is team-level access. It is valid for all projects under the account ID which created the connect API client. To use connect API, a project should always be set to N/A.
The project would be specified when server SDK is used in a project.
