I am trying to use the API to get membership data, including some custom fields. I have the general idea, I think. I can successfully retrieve the memberships, chained in the contact data, and now I need to include some data in custom fields. The table the custom data is stored in is called "college_data_1" and one of the custom fields is called "enrollment_3". So I believe I want entity 1 and field 3. I didn't find documentation that confirms how to find these IDs. So what I current have in API explorer is:
however this doesn't work. Help?
I will need to include website data too, next.
