Hi Wanling,
Thank you for reaching out to the Google Ads API team.
Moving forward to your concern, it appears that this is more of an Oauth related concern. That said, I would suggest reaching out to the Google Oauth support team via this
link as they are more equipped to provide guidance to you.
Just to add, on Google Ads API perspective, you can consider using
client libraries as it is no longer using the OOB and using the updated Oauth flow.
Regards,
