Subscribe Pro provides a powerful feature we call User-Defined Fields (UDFs). UDFs allows you to store your own data in the Subscribe Pro commerce platform, and allows you to wire that data in to various sections of the business logic which run inside the Subscribe Pro subscription engine.
Subscribe Pro allows UDFs to be defined and store on the following entity types in our data model:
|Data Model Area||Entity Type|
|Catalog||Group Subscription Template|
