This project demonstrates how one entity (a “reseller”) could package a set of files that would enable another entity (a “publisher”) to add Yahoo!‘s Updates API event notifications to a given file with very little technical interaction. A user (“user”) of the publisher’s site can then authorize the publisher’s site to publish updates on the user’s behalf via OAuth.

The example use-case this project is modeled after is as follows: a company produces a Yahoo!-Updates-enabled comment box that another company can install to easily enhance its blog by allowing readers to update their friends when they leave comments on the blog. The files in this project would be of greatest interest to those providing a service like the comment box producer in the example.

• Register an ‘OAuth app’ with the Yahoo! Developer Network (YDN, developer.yahoo.com)
• Define the ‘KEY’, ‘SECRET’, and ‘APPID’ in config.php using the values provided by the YDN app dashboard
• Define ‘CALLBACK’ in config.php as the installation domain
• Upload this code to a server
• Load demo.html in a browser
• Click the “Share via Yahoo!” button to authorize the publisher’s site to publish updates to Yahoo!
• Trigger publication by clicking the “Post Comment” button
