This reference explains the Custom Object: Create Record task.

This task creates a record of an existing custom object definition. You can create a custom object definition using the custom object APIs or from the Zuora Data Model UI.

When creating the task, you need to select a custom object definition from the list and specify values for the data fields of the object.

If you have created a custom object definition or a field definition of a custom object but it is not displayed in the drop-down list, refresh the Workflow cache. To learn about how to refresh the cache of Workflow, see Workflow maintenance settings.

To learn more about custom object definitions and records, see custom object definitions and custom object records.
