I have a custom post type called Offers, and in this post type is a custom field called Store, which is a relationship field type to another custom post type Stores.
This has been created using the Pods framework.
I'm using the JSON API plugin to get a feed of Offers, and you can include custom fields via the URL, as such:
This naturally only returns the ID of the Store post though.
How can I return not only the Post Title of the Store, but a further custom field from the Store post itself?
