Hi Duong, The error OAUTH_TOKEN_INVALID <https://developers.google.com/adwords/api/docs/common-errors#AuthenticationError.OAUTH_TOKEN_INVALID> occurs when your access token passed with the HTTP header was not correct. To verify that your credentials are correct, you could also try the CURL request provided below and see if you are able to generate the access tokens? If the credentials are correct, you should get an access token for the below request.
curl https://www.googleapis.com/oauth2/v4/token \ -d refresh_token=your-refresh_token \ -d client_id=your-client-id \ -d client_secret=your-client-secret \ -d grant_type=refresh_token If your credentials are incorrect and still facing issues then could you generate a new refresh token with the help of this guide <https://developers.google.com/adwords/api/docs/guides/first-api-call#get_an_oauth2_refresh_token_and_configure_your_client> and retry your request? Also, please make sure that you are authenticating as the Manager account <https://developers.google.com/adwords/api/docs/guides/accounts-overview#managedcustomerservice> while making this call. If you are still facing an issue please share the client customer id of your AdWords account and manager AdWords account.
