Hi Yanfang,
I had to edit your initial post as it contained sensitive details about your customer's account. You may check out our forum posting guidelines to avoid sharing confidential information publicly.
As for your concern, I checked your MCC account and it was not explicitly declared that the intended use was for the AdWords API. Additionally, the terms and conditions have not been checked. You may try and reach out directly to the Compliance Team via this
link in order to apply for the correct intended use of your developerToken. Also, you may already complete the terms and conditions by agreeing in your MCC's API Center.
Thanks and regards,
Peter
Google Ads API Team
