How many fields and feedback types can currently be sent back / supported when using LeadConduit Lead Feedback feature?

In addition to the type of Feedback and a reason/comment from the recipient, Feedback’s response to the submitting Source can optionally include any of the flow fields, the Lead ID, the Feedback event’s timestamp, the lead’s original submission timestamp, and any appended data.

Which data are sent back to the Source and the manner in which it’s sent (batch file or HTTP) is controlled by the flow, not by the Recipient or the Source.

There are only two Feedback types: Conversion or Return. A single Feedback event can only be of one type. A recipient can send Feedback multiple times for the same lead if, for instance, a lead was first marked “converted” but later was “returned”.
