Welcome. We are excited that you are interested in the Yammer Platform. Our platform consists of a set of open APIs and tools that enable you to bring Yammer’s social services to your application.
Build a basic Yammer app in a matter of hours . Before you begin, leverage the knowledge of thousands of Yammer platform experts by joining the YDN at https://www.yammer.com/yammerdevelopersnetwork
Socialize your app’s activity and grow it’s usage in an organization using Open Graph, a light weight data integration protocol.
Sign up and authenticate enterprise users into your app, with their Yammer credentials, using Oauth 2.
Underlying the Yammer platform are rich, easy to use REST APIs that are used by Yammer’s own clients (web, mobile).
The Yammer Realtime API is a JSON HTTP API using the Bayeux protocol to deliver realtime “push” messages.
These are older APIs that are on the chopping block for removal. Feel free to use them to debug apps that are currently in production, but please plan to migrate away from them as soon as possible.
