* Managing watchlists
* Creating and editing lists
* Rating movies and TV shows
* Marking content as a favorite

## Types of Sessions in TMDB API

### 1. Guest Session ID

* Created using the `3/authentication/guest_session/new` endpoint.
* Expires after 24 hours.

### 2. User Session ID

* Requires authentication via a request token and login credentials.
* Created using the `/3/authentication/session/new` endpoint.
* Used for actions tied to a TMDB account, such as managing watchlists and lists.
