Yammer is an enterprise social network service that was launched in September 2008.Unlike Twitter, which is used for broadcasting messages to the public, Yammer is used for private communication within organizations or between organizational members and pre-designated groups, making it an example of enterprise social software. Yammer originally launched as an enterprise micro blogging service and has evolved to become a fully-fledged enterprise social network.
Yammer Offer its API to create personalized yammer applications for mobile phones and desktop, to in this tutorial we will make and application, authorize it and access data from user profile. To access data from yammer api one passed from following steps
- Register your Application on Yammer and get Application Secret and Application Key.
- Then get Token and Token secret from above data.
- Then Authorize your application using the token and get the Auth Code.
- Then Auth Code, token and token get the access token and access token secret.
- Finally get Data from the user profile.
And now get all the obvious stuff out of the way and
let the code talk :) i made a small application demonstrating said steps.
