Rules and guidelines for Zuora REST V2 custom fields
Consider the following rules and guidelines to read data from or insert data to custom fields in Zuora:
•If you want to retrieve custom fields for all the Zuora objects, you can specify ALL instead of specifying all the Zuora objects in the Custom Field Config property.
•When you select the value of the Zuora API Version as Zuora Swagger API V1_2017_09_06, the custom fields do not appear in the Field Mapping tab.
•When you do not have the required API role or permission for the Zuora object specified in the Custom Field Config property, the custom fields do not appear in the Field Mapping tab.
•When you specify an object that does not support custom fields in the Custom Field Config property, the custom fields do not appear in the Field Mapping tab.
