Hi @jasonalvis, I'm not exactly sure what you want to know, but in order to use the v4 mixed lists you specify a media type with each list element. For example to add or remove items you would specify the following in the body of the request.

{ "items": [ { "media_type": "movie", "media_id": 550 }, { "media_type": "movie", "media_id": 244786 }, { "media_type": "tv", "media_id": 1396 } ] }

I'm on this same wavelength. When I retrieve the List Details from a mixed-type list, the records for TV shows return with empty titles:

Colum Column1.backdrop_path            type_and_id Column1.title   Co Column1.origina
FALSE /fK5ssgvtI43z19FoWigdlqgpLRE.jpg movie:10681 WALL·E          en WALL·E         
FALSE /97eLP7iJTCE03LhwtXfXRcLbg5H.jpg movie:13368 White Christmas en White Christmas
FALSE                                  tv:965                      en                
FALSE /ziC23LkMYj8gToQQYQGWSGJCLNF.jpg movie:82690 Wreck-It Ralph  en Wreck-It Ralph 
FALSE /wdVM1soj2s9ixta8R7NDwoZA12Y.jpg movie:9489  You've Got Mail en You've Got Mail

I'd love to be able to pull movie and tv titles directly within the same list details call, as opposed to having to go back later and add in all the details for tv entries.

Hey @Wajeemba,

Notice that the field names are different between movies and TV shows. For TV, you need to use original_name and name.
