Hi, I cant find this in docs https://developer.infusionsoft.com/docs/rest/#!/Contact/listCustomFieldsUsingGET
I need to create custom fields via REST API, oauth. XML-RPC docs has this explained: https://developer.infusionsoft.com/docs/xml-rpc/#data-create-a-custom-field
So, how to do this in REST API?
One more question - what’s the difference between XML-RPC API and REST oauth version? One of them is outdated, will be closed? Are the any drawbacks of using XML-RPC version?
