Hi Ankit,
I had to delete your initial post as it contained your OAuth2 credentials information.
Moving forward, there is currently no API feature to look up if a refresh token has expired. An error would be returned automatically in such an event. I would also recommend that you check out this
guide on the possible reasons why your refresh token might expire.
Regarding the
Error 403: org_internal, our team is unfamiliar with the link that you provided. If you have concerns on how to generate your credentials and is encountering errors doing so, I would recommend that you reach out to the Google API Console support team instead via this
link for further guidance.
Best regards,
