Payload Merging

Payload merging occurs if there is an outbound payload waiting to be sent, but the base record associated with that payload is updated before that payload is sent. This means that for most updates only a single payload per record is ever sent, with the payload reflecting the most up-to-date values.

However, merging does not occur if any important update field had its value changed during the update. Instead, a new Outbound Payload record is generated and will be added to the end of the queue of insert and update payloads to be sent.
