  • Introducing the Create Consumer Key API

    Today, we are launching a new feature on the Yahoo! Developer Network called the Create Consumer Key API. A few weeks ago we posted a sneak peek. This blog post touches again on what it is, who should use it, and adds links to API documentation and example integrations.

    About the CCK API

    Many developers who use Yahoo! Web services and APIs distribute applications that allow their users to access their own Yahoo! user data. This requires you as the developer (the third party) to have your own OAuth Consumer Key and Secret, while ensuring each of your users (the fourth party) also have their own distinct OAuth credentials. The Consumer Key ensures that the right data, for the right user, is going to the right developer.

    The Create Consumer Key (CCK) API allows developers to easily provide Yahoo!-issued Consumer Keys, Consumer Secrets, and Application IDs to their users.

    The CCK API offers the following benefits to developers:

    Streamlines the process of using your application: Your

  • Yahoo! plans to do a lot of recruiting at conferences this year, to get the word out
    that we're actively hiring all kinds of engineers. We'll be hosting an invite-only recruiting event for service engineers at our Sunnyvale headquarters later this week. If you're interested in attending, or learning more about all the engineering opportunities at Yahoo!, visit our global careers site to request an invite.

    Recently, on February 20th and 21st, Yahoo!'s Talent Acquisition group, along with several service engineers attended the Southern Californian Linux Expo in Los Angeles, California to recruit top-tier service engineering talent.

    The Southern California Linux Expo brings together Linux and open source vendors, developers, educators, and users for 3 days of talks, exhibits, tutorials and networking.

  • Yahoo!’s Partnership with Twitter

    hummingbird-announcement_sm.jpgToday Yahoo! announced a partnership with Twitter which includes integrating Twitter content and social features across the Yahoo! network.

    Public Tweets are already available in Yahoo! search results and you will see them appear more frequently, for more of your queries. Soon you will see topics in Yahoo! News, Finance, Sports and Entertainment enhanced with relevant real-time Tweets.

    A key driver for this Twitter partnership is to enable Yahoo! users to share and stay connected more easily with the people and things they care about across the web, in keeping with our Yahoo! Open Strategy and platform. We announced the first phase of this Social Aggregation Strategy back in December when we outlined our plans to implement Facebook Connect on Yahoo!. Adding Twitter to our users’ experiences is the next phase in this strategy and it further expands the power of the Yahoo! ID as a single key that gives our users an access token to the best of the web. Whether they want to check their

  • Yahoo! Search Developer Tools and the Yahoo! and Microsoft Search Alliance

    For many years, developers have been building amazing applications that leverage search tools and services from Yahoo!. We know you may have questions related to today’s announcement about DOJ and EC clearance of the Yahoo! and Microsoft search agreement. We don’t have all the answers today, but we are working through the details and will provide updates for developers as soon as we can.

    Yahoo! Search BOSS

    With the implementation of the search alliance, the BOSS team is excited to examine the Microsoft web, image, and video search technologies in more detail. Yahoo! may continue to offer the BOSS service, which would integrate some Yahoo! services and content with algorithmic results provided by Microsoft. The team is exploring what a future offering could consist of, with some services powered by Microsoft and unique content provided by Yahoo!. As we finalize details for any changes to the BOSS service, we will give developers plenty of notice.

    Also, prior to the announcement of the

  • Sneak Peek at the Create Consumer Key API

    In about a month we'll be launching a new feature on the Yahoo! Developer Network (YDN) called the Create Consumer Key API (CCK API). This blog post is a sneak peek-- describing what it is, who should use it, and how interested 3rd parties can start integrating with it early.

    What is it?

    Many developers who use Yahoo! Web services and APIs distribute applications that enable their users to tap into Yahoo! user data (with user permission). In these cases, both the developer and each of their end-users signs up for a distinct OAuth Consumer Key. The Consumer Key ensures that the right data, for the right user, is going to the right developer.

    YDN aims to make it easier to broker out or sub-syndicate access to Yahoo! data, so we have been working on a programmatic way to trigger the creation of Consumer Keys.

    The CCK API offers the following benefits to developers:

    Streamlines the process of using your application: Your users do not separately request an OAuth Consumer Key from YDN.

  • Video: Improving the Performance and Security of AJAX Web Applications

    Knowledge sharing at a tech company is a big deal, and here at Yahoo!, one of the ways we facilitate that is through regular Tech Talks. Topics cover everything from a quick refresher on an internal service or tool to in-depth discussions of HTML 5 and other new technologies to how to stress-test an API before release. Last Friday we hosted Ben Livshits, from Microsoft Research, who shared his work on how to improve the performance and security of AJAX web applications. Here's the video:


  • Some Facts About the Yahoo! Shopping API Shutdown Announcement

    Yes, it's true. The Yahoo! Shopping API is shutting down on March 11, as part of our strategic partnership with PriceGrabber to power the backend product listings functionality on Yahoo! Shopping. I've read the commentary here on the blog and out in the blogosphere. I've also read some of the speculation about what this means -- and it's dead wrong. Yahoo!'s commitment to developers and to open platforms is not going away. Not at all.

    That doesn't mean time stands still and everything stays the same. As Yahoo! continues to refocus and rewire, businesses change and priorities shift. Strong leaders make tough decisions all the time. The Open Web is not a rose garden. You know that.

    I know we need to do a better job of sharing information whenever possible. Providing roadmaps, getting your feedback, offering viable alternatives when a service like the Shopping API is affected by changes in our business. We’re on it.

    In 2010, you'll hear more from me and the rest of the YOS team about the

  • Linking Your Facebook Account on Yahoo!

    Last week Yahoo! announced that we’re working to integrate Facebook features across our network. I wanted to share some of the implementation details so that developers understand what we’re working on. We're thrilled about the work that's underway.

    Facebook Connect on Yahoo!

    First off, I want to take the opportunity to clarify some misperceptions that we’ve noticed: the Facebook deal is not a “login” agreement. It will not be possible to sign in to Yahoo! with a Facebook ID. Rather, we’re using Facebook Connect to enable Yahoo! users to authorize data sharing between the sites. With this agreement, logged-in Yahoo! users will be able to bring the social stream that’s relevant to them on Facebook into their Yahoo! account and to publish their social activities on Yahoo! (e.g., Flickr photo uploads, article comments, etc.) to Facebook.

    This is all great for our users. The Yahoo! ID becomes a single key that allows users to check their mail, their news, and their Facebook newsfeed all
