Retrieves the full items referenced in the specified field of an item.
Reference and multi-reference fields refer to items in different collections. Use this endpoint to retrieve the full details of the referenced items themselves.
For example, suppose you have a Movies collection with an Actors field that contains references to items in a People collection. Querying the Movies collection using the Query Referenced Data Items endpoint returns the relevant People items referenced in the Actors field of the specified Movie item. This gives you information from the People collection about each of the actors in the specified movie.
