403 Forbidden error for bds/list request


We have two environments, one for testing and the other is PROD environment. I am working on testing environment.

Thus, I am using baseURL like: https://****test.brightspace.com

My request is:

Response 403 Forbidden:
"type": "http://docs.valence.desire2learn.com/res/apiprop.html#not-authorized",
"title": "Not Authorized",
