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 Interesanteintegrated 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.

Use The Source, Luke!
Since the most fun way to work with it is to try it, we’ve prepared a few code examples in Python and JavaScript to get you started. For a more comprehensive client-side app using the Topics API, try the Topics Explorer. You can find its source code on code.google.com.
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.
When we began building the new YouTube app for Nintendo Wii, we wanted to make video playback smooth and beautiful. This meant squeezing the most available power from the console CPU and fitting the video decoding process within the tight bounds of available memory. After trying out several video encoding formats on Wii, we found that 360p WebM encoding performed the best. With the largest install base of current generation consoles, YouTube on Wii is the largest deployment of WebM video in the world today.
WebM is particularly well-suited to devices where available memory is limited, because of its technical approach to video encoding. VP8, the video codec in WebM, uses reference frames (called alternative reference frames, or "alt-ref") from which adjacent video frames are derived and compressed. This type of compression is commonly used in modern video encoding schemes, but VP8 uses the technique with particular efficiency, which results in a smaller memory footprint and smoother video playback on Wii.
We went one step further and performed low-level optimization of the VP8 decoder specifically tuned to the Wii’s processor. This included: using paired-single floating point operations to perform motion compensation, loop filtering, and idct; using the GPU to do color conversion and scaling; and dcbz instructions to copy buffers. This kind of optimization is available to anyone, as the VP8 code is open source under a BSD license.
We’ll keep looking into other ways we can use WebM, so stay tuned on this blog to learn more.
If you’re a developer who uses the YouTube API, and if you make your requests to the API using HTTPS, there’s an upcoming change that you should be aware of. Sometime in early 2013, Google will be changing the certificates used for establishing secure HTTPS connections to all of our servers, in what we anticipate will be a backwards-compatible manner. Still, since there are so many slight differences in HTTPS client implementations, we encourage you to test your existing code in advance of this change and to report any issues that you do encounter.
To confirm compatability today in advance of the production change, you can make test API requests to stage.gdata.youtube.com and uploads.stage.gdata.youtube.com using version 1, 2, or 2.1 of the Data API, as described in this blog post about our staging environment. The new certificates are already in place on those servers. Be sure that you’re using https:// as the protocol.
If you’re using HTTP instead of HTTPS to access the YouTube Data API then you also won’t be affected by the new security certificates—but you really should start using HTTPS!
Developers who still rely on ClientLogin for handling authorization (which we also don’t recommend) have one additional thing to test, even if your actual YouTube API requests don’t use HTTPS: ClientLogin requests are made https://www.google.com/accounts/ClientLogin. Because we do not have a staging domain name set up for www.google.com, the recommended way of testing ClientLogin in advance of the certificate change is to hardcode the IP address 74.125.130.105 for the domain name www.google.com in the /etc/hosts file of your computer. Be sure to remove that entry when you’re done testing.
We don’t yet have a specific date in mind for making the switch in production, and when we do, it will be added as an update to this blog post. Please don’t wait until the last minute to test your code, though!
We're constantly amazed at the innovative ways that developers incorporate YouTube into their applications.
