Audit Trail between Contact and Custom Objects
On the current setup, we have a custom object where we set Primary and Secondary Contact which are from the Contacts object. Any changes to the contact details of a Contact/Person is being done on the Contact object itself where we drill down to a record and make the updates. If there are any changes, they are also reflected on the custom object.
Would it be possible to access theese changes (old and new values) on the contact details of the Contacts via REST?
Currently, we are using the below URI but the problem is we won't be able to connect the Contact and its changes to the custom object we have? Would that be possible?
