Contract Data Changed · Developer Docs

Sent whenever data of a contract has changed. This occurs if you execute a PUT/PATCH on a contract, update customfields or the external Id.

Typical Scenario

You want to listen to this hook to make sure your system gets notified when there was a change. To find out what the current state of the contract is, simply fetch the referenced contract by id.
