POST /feedback?event_id=... identifies the lead by the delivery
event ID that LeadConduit shared with you when the lead was delivered. POST /feedback/{recipient_name}
identifies it by the record ID you stored on your side, and lets a CRM-specific integration parse
the payload. Neither needs an API key: the event or record ID is what authorizes the request.
Feedback must be enabled on the delivery step before recipients can use these endpoints. See
Enabling a Recipient to Send Conversion Feedback to LeadConduit
and Sending Feedback to LeadConduit
in the help center.
