Insufficient Permissions (403)

[Adigami]

We have set up a Google project for accessing several of the Google APIs, including the DCM/DFA API. And we have authenticated and received an OAuth access token with both the reporting and trafficking scope. 

However, when we want to get a list of advertisers, creatives, or placements, we receive a 403 (insufficient permission) error:

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission"
   }
  ],
  "code": 403,
  "message": "Insufficient Permission"
 }
}

The user profile has the following (and many more) permissions checked off for their role:

Advertiser management: read-only access
Creatives: read-only access
Placements: read-only access
Sites: read-only access to properties

What else could be the issue here?

Thanks for your help.

Hi there,

This sounds like an authorization problem, rather than a problem with permissions. It could be that either the reporting or trafficking scopes are missing, depending on the action you're trying to take. I suggest going through the authorization process again to generate a fresh access/refresh token pair, paying close attention to the Google account you're authorizing and the scopes requested.
