Not seeing anywhere where it’s possible to revise/update an existing Custom Field through the REST API (Custom field is on the contact record model). Is this possible or will I need to do this operation through the XML-RPC API?
You’re right, we currently don’t have a mechanism for changing Custom Fields (either in relation to groups or types) via the REST API, but it’s something we hope to get included. The same Access Token you’re using for the REST API should work to perform the updates via XML-RPC though.
Yep. I’d already tested it out there since I hadn’t found it in the REST API so I’m good to go.
Thanks for the followup!
