href="/web/20220315060001/https://developers.google.com/youtube/terms/developer-policies-guide">Complying with the YouTube Developer Policies</a> guide provides guidance and examples to help you ensure that your API clients adhere to specific portions of the YouTube API Services <a href="/web/20220315060001/https://developers.google.com/youtube/terms/api-services-terms-of-service">Terms</a> and <a href="/web/20220315060001/https://developers.google.com/youtube/terms/developer-policies">Policies</a> (API TOS). This guidance offers insight into how YouTube enforces certain aspects of the API TOS but does not replace any existing documents.</p> <p>This document defines minimum functional requirements for API clients that implement or provide access to specific features of YouTube API services ("API Clients").</p> <p>These requirements and guidelines ensure that API clients provide a consistent user experience that protects the interests of YouTube users, content owners, and advertisers. These rules are an integral part of the <a href="/web/20220315060001/https://developers.google.com/youtube/terms">YouTube API Terms of Service</a> and must be followed in the development and implementation of any API Clients.</p> <p>You should expect the requirements in this document to change so that we can ensure better user experiences with existing YouTube features. They will also change in response to new and updated YouTube features. At times, such changes may require you to update your API Clients to address new requirements. The <a href="/web/20220315060001/https://developers.google.com/youtube/terms/revision-history">Terms of Service revision history</a> will document any changes, so please check that document frequently, or subscribe to its <a href="/web/20220315060001/https://developers.google.com/youtube/terms/feeds/api-services-terms-of-service-revision-history.xml">RSS feed</a>, to ensure that you can quickly learn about changes that may affect your API Clients.</p> <p>In addition to the requirements in this document, we highly recommend that you follow best practices described in the <a href="/web/20220315060001/https://developers.google.com/youtube/terms/developer-policies">YouTube API Services Policies</a> and discussed elsewhere in YouTube API services' documentation. Even when not strictly required, these practices help your API Clients to recover more quickly from errors and to optimize their quota usage if they use YouTube API services that allocate quota. At the same time, these practices help to ensure the health of the YouTube ecosystem and, above all, to provide the best experience possible to users of your API Clients and of YouTube Applications.</p> <h2 id="youtube-embedded-player-and-video-playback" data-text="YouTube embedded player and video playback">YouTube embedded player and video playback</h2> <p>The requirements in this section relate specifically to embedded YouTube players. The YouTube API Services Policies also includes several policies relevant to API Clients that play YouTube audiovisual content.</p> <h3 id="embedded-youtube-player-size" data-text="Embedded YouTube Player size">Embedded YouTube Player size</h3> <p>Embedded players must have a viewport that is at least 200px by 200px. If the player displays controls, it must be large enough to fully display the controls without shrinking the viewport below the minimum size. We recommend 16:9 players be at least 480 pixels wide and 270 pixels tall.</p> <h3 id="autoplay-and-scripted-playbacks" data-text="Autoplay and scripted playbacks">Autoplay and scripted playbacks</h3> <p>This section covers automatic playbacks. It applies to YouTube embedded players that either use the <code translate="no" dir="ltr"><a href="/web/20220315060001/https://developers.google.com/youtube/player_parameters#autoplay">autoplay</a></code> player parameter or programmatically initiate automatic playback using the YouTube IFrame Player API service, the YouTube Android Player API service, or another YouTube API service.</p> <ul> <li> <p>Embedded players that automatically play a video should initiate playback immediately when the page loads or as soon as the embedded player is fully visible. However, an API Client must not initiate an automatic playback until the player is visible and more than half of the player is visible on the page or screen.</p> </li> <li> <p>A page or screen must not have more than one YouTube player that automatically plays content simultaneously.</p> </li> <li> <p>Any YouTube thumbnail that initiates a playback must be at least 120 pixels wide and 70 pixels tall.</p> </li> </ul> <h3 id="youtube-player-attributes" data-text="YouTube Player attributes">YouTube Player attributes</h3> <p>Attributes and parameters of the YouTube player – including, for example, the appearance of YouTube branding in the player – are specified in YouTube API documentation and specifications (https://developers.google.com/youtube). You must not make changes to the YouTube player that are not explicitly described by the API documentation.</p> <h3 id="overlays-and-frames" data-text="Overlays and frames">Overlays and frames</h3> <p>You must not display overlays, frames, or other visual elements in front of any part of a YouTube embedded player, including player controls. Similarly, you must not use overlays, frames or other visual elements to obscure any part of an embedded player, including player controls.</p> <h3 id="mouseovers" data-text="Mouseovers">Mouseovers</h3> <p>You must not use mouseovers or touch events on a YouTube player to initiate any action on the user's behalf, such as opening a window or subscribing to a channel.</p> <h2 id="uploading-videos" data-text="Uploading videos">Uploading videos</h2> <p>If API Clients allow users to upload content to multiple platforms, users should be able to select and deselect the platforms to which they want to upload their videos.</p> <h3 id="data-requirements" data-text="Data requirements">Data requirements</h3> <p>API clients that enable users to upload videos to YouTube must enable <em>users</em> to set the values in the following list.
