Web App Example Not working


Your sample web project is not working. I guess this has to do with Yammer changing something the authentication process on december 2013.

In the AuthCode action, the myYammer.GetToken() returns null:
var myConfig = this.TempData["YammerConfig"] as ClientConfigurationContainer;
myConfig.ClientCode = code;
var myYammer = new YammerClient(myConfig);
var yammerToken = myYammer.GetToken(); // returns null

Very cool Project!

To make it run we needed to Change the YammerRequest class in YammerClient.cs.
There´s a comment that request.AddBody(objectForRequest); should be used instead of the complex AddObject-method but with that code you won´t get an AccessToken.
Replace the AddBody by request.AddObject(objectForRequest); - then the project works!

//Request Format set to JSON and AddBody instead of AddObject
//are necessary to allow posting complex objects (such as the Activity object)
request.RequestFormat = DataFormat.Json;
// Do not use this: request.AddBody(objectForRequest);
// This works:

Credits goes to Andi Lillich ( - thx for finding and fixing!
best, Toni
