changeStamp

A changeStamp is a required parameter for the body of a PUT (update) operation for these objects:

• feed
• campaign
• filter
• reply template
• notification
• social contact
• predefined response

A changeStamp is returned as part of a read or creation operation. You must include the changeStamp in any modify or delete request (a method known as optimistic locking) to prevent clients from unintentionally overwriting each others' data. If you do not provide a changeStamp or the changeStamp is out of date, the update fails.

If the update succeeds, the database increments the changeStamp by 1.
