Hi Soni,

Thanks for reaching out to the Google Ads API team. I hope you are doing well today.
 

The "invalid_grant ” error usually indicates an issue with the refresh token. That said, you will need to regenerate credentials and refresh tokens. You may refer here to this guide for the steps on how you can regenerate credentials and refresh tokens.
 

If the issue still persists after the provided suggestion, you may note that the logs you have provided were not complete, with this, you may provide to us the complete API logs (request and response logs with request ID) generated on your end which include the invalid_grant error.

You can provide it via Reply privately to the author option. If this option is not available, then send it instead on this email address googleadsa...@google.com.

Regards,

Darwin Google Ads API Team
