Hi, Currently we can only respond in English. The error code AuthenticationError.OAUTH_TOKEN_INVALID <https://developers.google.com/adwords/api/docs/common-errors#AuthenticationError.OAUTH_TOKEN_INVALID> indicates that there's an issue with the access token in the Authorization header. It usually means the token has expired, which you can confirm via the URL below after appending your *access* (not refresh) token to the end.
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token= <https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=YOUR_ACCESS_TOKEN> Are you using one of the client libraries <https://developers.google.com/adwords/api/docs/clientlibraries>, or constructing the OAuth and API requests manually?
