For each resource type, the guide lists one or more data representations, and resources are represented as JSON objects. A resource represents a type of item that comprises part of the YouTube experience, such as a video, a playlist, or a subscription. This reference guide explains how to use the API to perform all of these operations. The API also supports methods to insert, update, or delete many of these resources. The lists below identify the different types of resources that you can retrieve using the API. The YouTube Data API lets you incorporate functions normally executed on the YouTube website into your own website or application.
