Hi,

Thanks for posting your concern.

It appears that you've already raised this issue in another thread and I already responded there. However, I will also post my reply on this forum thread.

I can see that you encountered the invalid_grant error and the reason why this error is occurring is when access or refresh token being passed in your request is incorrect / invalid / expired. With this, please try generating a new set of OAuth credentials by following the guide here which includes getting of OAuth2 refresh token and configuring client library.

Please also configure your C# client library by following this guide, for logging API transactions, so that you can provide the complete request and response logs with request ID if you encounter further errors / issues.

Regards
