Source Types Reference

How to use this reference
Start from the provider your webhook traffic comes from. The provider page tells you what to paste into the provider dashboard, what to enter in FastHook, which validation requests FastHook answers, and where rejected requests will appear when the provider sends the wrong method or signature.
