The Simpler, Yet More Powerful New YouTube Data API

2012年12月14日星期五

Since its initial launch in 2007, the YouTube Data API has become one of Google’s most popular APIs by request volume, thanks to the awesome apps from developers like you. To help you make better integrated video experiences, you can now use the YouTube API version 3.0. The new API is easy to use thanks to rich client library support, improved tooling, reference documentation and integration with Google’s common API infrastructure. Version 3.0 only returns what you ask for and is using JSON rather than XML encoding for greater efficiency. The API introduces new core functionality including Freebase integration via topics, and universal search. If you develop social media management apps, you’ll love channel bulletin post and full subscriber list management, also new in this release. Version 3.0 of the API constitutes the API's biggest overhaul to date and we’re eager for you to try it today!
New Functionality: Topics, Universal Search, and Audience Engagement Support
Have you ever tried to search for YouTube videos only to find out that keyword search can produce ambiguous results? With the new Topics API, thanks to the power of Freebase, you can find exactly what you’re looking for by specifying Freebase topic IDs rather than search keywords.

For example, if you’re reading this post from outside of the US and would like to search for content related to football, /m/02vx4 is probably the topic ID you're after. The API's universal search feature lets you retrieve channels, playlists and videos matching the topic with just one request like this one. Find out more in our Topics API Guide.

Version 3.0 introduces better tools to engage and interact with one’s YouTube audience. Social media management apps can now help content creators communicate with their channel subscribers using buletin posts.
Efficiency, Client Libraries, Better Tooling and More!
To help you reduce your app’s bandwidth requirements version 3.0 only returns the information you ask for as specified by the “part” parameter.

While the default JSON encoding in version 3.0 is more efficient than XML in version 2.0, if parsing JSON isn’t your thing, check out the client libraries for .NET, Dart, Go, Java, JavaScript, Objective-C, PHP, Python and Ruby. The libraries use OAuth 2.0 authorization and work with the YouTube API as well as other modern Google APIs thus simplifying your application.

The familiar Google API tools such as the API console work with YouTube API version 3.0 without any extra hassles. Additionally, our API reference documentation now allows you to scroll down to the bottom of any reference page to try the API. You can also or visit the standalone API Explorer to browse a list of supported methods.
App Examples
Even though version 3.0 is still experimental, a number of exciting new apps are already using it. Let’s look at a few examples:

Showyou, an app that makes it easy to watch the Internet, integrated the Topics API to enable users to discover related videos after tapping on topics associated with the Showyou feed.

Argentina-based Interesante integrated the Topics API to determine the Freebase topic of videos being shared. Interesante used this to serve interest-based video recommendations.

FanBridge, a company specializing in growing and managing one’s fan base, recently introduced channel bulletin post functionality with scheduled posts support.

Tubular Labs, which focuses on YouTube audience development, uses subscriber list to help content creators develop a better understanding of their audiences.

Pixability, a company specializing in YouTube marketing software, was able to quickly port their Online Video Grader to the YouTube API version 3.0 thanks to the new Python client library.

ClientLogin using Google Accounts

2012年12月11日星期二

Long-time readers might remember a blog post from a while back entitled “ClientLogin #FAIL”, in which we covered the myriad ways in which your ClientLogin authorization attempts might result in an error. Even though ClientLogin has been officially deprecated since April 2012, and even though we’ve been recommending that developers switch to OAuth 2 for longer than that, we know there are still a good number of legacy applications out there that still rely on ClientLogin.

If you are a developer of such an application, there’s another thing that you (and your users) will need to start watching out for: at some point in the future, we will start requiring that the username parameter passed to ClientLogin (i.e. what’s referred to as the Email= value in the ClientLogin request) correspond to the full email address of the Google Account that’s associated with an underlying YouTube channel. We’ve supported using Google Account email addresses with ClientLogin for many years now, ever since we started linking Google Accounts to YouTube channels, but old habits die hard, and many users still use YouTube usernames.

We haven’t yet determined a date for when we still stop supporting ClientLogin with YouTube usernames and will provide additional details when we know more about when it will take place. However, if you use ClientLogin, it’s not too early to start encouraging your application’s users to start providing their Google Account email addresses instead of their YouTube usernames when logging in. If you have the ability to update your existing application’s user interface, we recommend doing so to indicate that the username field should take a Google Account email address. If you have any online help materials or technical support for your software, update them to ensure that users know to provide their Google Account email address.

Users who log in via the YouTube.com web interface, or who go through the AuthSub, OAuth 1, or OAuth 2 web authorization flows will soon be required to use their Google Account email address instead of their YouTube username as well. This web-based transition will take place well before we deprecate YouTube usernames for ClientLogin, and it should be transparent to developers since Google controls the user interface for these flows. For more information, see this help center article.

As mentioned, we’ll have a follow-up post in coming months with more details about exactly when we’ll stop supporting YouTube usernames with ClientLogin. That post will also communicate the exact error message that ClientLogin will return when a YouTube username is used. We’d like to close with one more plea: ClientLogin is deprecated, and is technically inferior to OAuth 2 in a number of important ways. Our new Google APIs client libraries provide first-class OAuth 2 integration that developers can take advantage of in their new code, or back port to their existing code. You will be doing your users a service and making their accounts more secure by transitioning from ClientLogin to OAuth 2.
Update (June 2013): The change mentioned in this blog post is now in effect. Attempts to use ClientLogin with a YouTube username will result in HTTP 403 Forbidden responses, with Error=BadAuthentication in the response body.Cheers,—Jeff Posnick, YouTube API Team
