Hi,
I guesss, it's because the account you granted access to AdWords and the
account you were trying to make a request against are different (or not
under the MCC you granted access).
Please make sure you grant access to an MCC account or a client account.
And the account you are trying to make a request is under the MCC or the
client account you granted access.
Best,
- Takeshi, AdWords API Team
