Impersonation Token and (401) Unauthorized

Hi Stephane,
I'm attempted to do impersonation in proof of concept console application, and so far I'm able to make calls and get User Id's using my GAT. I ensured that I was a Verified Administrator in Yammer before I created the app. However when I make the call:

string impertoken = MakeYammerRequest(string.Format("https://www.yammer.com/api/v1/oauth/tokens.json?consumer_key={0}&user_id={1}", ClientId, UserId),

When YammerRequest.GetResponse() is fired, I get an 401 unauthorized message. I'm at a loss at what to check to ensure this works.




Hi Paul,

According to what you say, you should be fine...To make sure, you should monitor your traffic with Fiddler and see whether the authorization token is sent correctly. If it is and if the token isn't expired, then, I don't see what else you could look at.

Best Regards

Can you please help me with my problem. I'm getting a bad request when getting the impersonationToken. I can get the TargetUserId just fine. Help please..
