DuplicateMessageCheck Activity

Use the DuplicateMessageCheck activity to verify duplicate messages and avoid their processing.

To accomplish this, the activity uses a PayloadID. Any message that contains a PayloadID, that is, unique within the receiving organization is considered ‘new’. If the PayloadID provided to the activity was previously received, the activity sets the IsDuplicate parameter to true. However, if the Fatal parameter is set to true, the activity throws an Exception - an ‘error’ transition can be configured to handle this.
