Help adding movies to "Favorites" list API 4

Служба підтримки The Movie Database

I need to add 5 of my favorite movies to this list using API 4 but I get a few different errors. The most common response is a 402.

Here is the syntax for my URL:

https://api.themoviedb.org/4/list/<list ID>/<ListofMovies>

An example URL would look like this:

https://api.themoviedb.org/4/list/7113143/MovieList

I'm still new to this so I'm sure there's something fairly simple I'm leaving out of my request.

Any help on this would be appreciated!!

It's a post request to this url 'https://api.themoviedb.org/3/account/{account_id}/favorite' then add session_id and api_key and in the body put some thing like this: { "media_id": 763215, "media_type": "movie", "favorite": true }
