Hi @jasonhampleman It looks like the Events were not authenticated. For
more details you can refer to
https://www.adobe.io/apis/experienceplatform/events/docs.html#!adobedocs/adobeio-events/master/intro/webhooks_intro.md#authenticating-events.
Also, I would encourage you to post questions on
https://experienceleaguecommunities.adobe.com/t5/adobe-i-o-events/ct-p/adobe-io-events.
We have more I/O Events experts on that forum.
