Hi,
Thank you for reaching out to the Google Ads API support team.
You may use the
OAuth Playground to generate refresh and access tokens. You can use this
guide for the steps on how you can regenerate credentials and refresh tokens. I would recommend you to check this documentation
Test credentials for more information. Also, could you please provide below details about the refresh token issue you're facing:
If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides
Java,
.Net,
PHP,
Python,
Ruby or
Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.
You can send the details via Reply privately to the author option, or direct private reply to this email.
