Custom Field PATCH



Refer to our documentation on URI syntax for more information on how to construct URIs.


This message enables you to edit custom fields for an existing customer or supplier. You do not need to specify if the contact is a customer or supplier. The fields available to a contact are defined from within the application and cannot be altered here (but you can get a list of them with a custom field metadata GET request).

You can use a single PATCH call to execute a batch of operations. Please refer to the HTTP PATCH documentation for a more detailed explanation of the operations and syntax of HTTP PATCH.

If successful, this endpoint returns the new state of the contacts's custom fields as if you had performed a custom field GET.
