Custom fields API overview
The custom fields endpoint if the SOAP API lets you retrieve details of and manipulate entries of custom collections in Smile.
Note: All custom field methods assume that the custom collection already exists. You cannot
define a new custom collection or delete a custom collection though SOAP. A custom collection
must be created through the Smile UI.
Smile emits SmileCustomCollection messages after it completes an action.
The custom fields WSDL is located at http://smile.example.com:port/stage/smile/ws/v2/config/customfields?wsdl
