Hello @DonnaP4507, I see that you've also contacted us on this issue via email, which we've replied to, however I wanted to close the loop on this post as well. The endpoint path you provided includes an extra segment. The correct endpoint is: https://api.cc.email/v3/reports/email_reports/{campaign_activity_id}/tracking/bounces The documentation for this endpoint can be referenced here: https://developer.constantcontact.com/api_reference/index.html#!/Email_Reporting/getBounces
