This page contans detailed explanation of each version, their features, and the differences between them.

TMDB offers two main versions of its API: v3 and v4

TMDB API v3

The v3 API is the most widely used version of TMDB’s API. It provides access to a vast amount of data, including movies, TV shows, actors, images, videos, and user-generated content. The v3 API is RESTful and uses JSON as its data format.

Key Features

• Movie Data: Access details such as title, release date, runtime, genres, ratings, and more.

• TV Show Data: Retrieve information about TV shows, including episodes, seasons, and cast.

• People Data: Get details about actors, directors, and other crew members.

• Search Functionality: Search for movies, TV shows, and people.

• Images and Videos: Access posters, backdrops, trailers, and clips.

• User Authentication: Supports user authentication for managing favorites, watchlists, and ratings.

• Pagination: Supports pagination for large datasets.

• Rate Limiting: API requests are rate-limited to ensure fair Usage

Example Endpoint

Get Movie Details:

GET https://api.themoviedb.org/3/movie/{movie_id}?api_key=YOUR_API_KEY

TMDB API v4

The v4 API is a newer version of TMDB’s API, designed to provide a more streamlined and secure experience. It introduces significant changes, including a new authentication method and improved security features. Unlike v3, v4 uses Bearer Token authentication instead of an API key.

Key Features

• Enhanced Security: Improved security measures to protect user data.

• Backward Compatibility: Works alongside v3, allowing developers to transition gradually.

• Limited Endpoints: As of now, v4 has fewer endpoints compared to v3, focusing primarily on authentication and user-related operations.

Example Endpoint

Get Account Details:

GET https://api.themoviedb.org/4/account?api_key=YOUR_BEARER_TOKEN

Requires a valid Bearer Token in the request header.

Differences Between v3 and v4

Feature	v3	v4
Security	Standard	Enhanced
Endpoints	Extensive (movies, TV, people)	Limited (focus on authentication)
Usage	Broad (data retrieval)	Primarily for authentication
Backward Compatibility	No	Yes (works alongside v3)

Which Version Should You Use?

• Use v3 if you need access to a wide range of data, such as movie details, TV show information, and search functionality. It is the most feature-rich and widely supported version.

• Use v4 if you are focusing on user authentication or need enhanced security features. However, note that v4 currently has limited functionality compared to v3.
