The POST Returns Endpoint is used by the Client to notify Check21.com of a return which has occurred. Most Clients use this Endpoint only when Check21.com cannot access the Client Returns automatically. Further, it is used as a way of allowing Check21.com to manage the transaction creation process, automatically blacklisting transactions which have been hard returned or have multiple sequential returns.
