Hi, In general, you may see OAUTH_TOKEN_INVALID <https://developers.google.com/adwords/api/docs/common-errors#AuthenticationError.OAUTH_TOKEN_INVALID> error if the access token in your request header is not valid. Access tokens have a limited time validity and they expire in 1 hour (3600 seconds). Our client libraries handle the mechanism of generating a new access token from your refresh token when an access token expires. Refresh tokens, on the other hand, do not expire and are meant to be kept safely in your local environment (should not be sent with your API call). Could you please download a fresh copy of the PHP client library <https://github.com/googleads/googleads-php-lib>, configure your OAuth credentials and check if you are able to get campaign information for your account when you run this example <https://github.com/googleads/googleads-php-lib/blob/master/examples/AdWords/v201702/BasicOperations/GetCampaigns.php> ?
