Credentials Revoked or Expired issue while Calling multiple APIs using same Service

[bsangamesh]

Hi API Team,

Based on our business requirement we are building a Analytics report using Campaign Manager 360 APIs like, get_campaigns, get_reports, patchReport, etc.., and as the API Documentation suggests we are using to dfareporting_utils.py build service object which can will be used to call all the API methods. We are using the same service object to call all these difference APIs sequentially.

It was working fine, but now we started getting "The credentials have been revoked or expired, please re-run the application to re-authorize"

Could you help us understand this and solve this issue?

Thanks,
B Sangappa
