Hi,
Thank you for your response.
As mentioned previously, there is no official Google Ads API client library in Node.js or React. Please use one of our official client libraries found here. In addition, to get started with using the Google Ads API, look through our Google Ads Developer Starter Checklist and our Quickstart guide.
One of the possible reasons for invalid_grant error is when your refresh token has been expired or revoked. You can refer to this documentation for more information on refresh tokens.
If you continue to encounter an issue despite following the guides provided above, kindly provide more information regarding your concern in order for us to provide accurate guidance and investigate further. Share with us the Complete request and response logs with request ID generated as shown in the respective links. Make sure to send the requested logs privately via the "Reply to Author" option or through our email (googleadsa...@google.com).
Looking forward to your response.
