Hi. We are trying to get Google Ads account statistics by API, we got a basic developer token. When we try to send requests, we get the following error:
PHP Fatal error: Uncaught GuzzleHttp\Exception\ClientException: Client error: `POST
https://oauth2.googleapis.com/token` resulted in a `400 Bad Request` response:
{
"error": "invalid_grant",
"error_description": "Token has been expired or revoked."
}
Google technical support, which issued access and wrote to the mail, does not respond with return letters. Thanks!
