Having trouble getting a Request Token for Yahoo Oauth

When I make the GET request, Yahoo responds with oauth_problem = consumer_key_unknown.

I am following this documentation: http://developer.yahoo.com/oauth/guide/oauth-requesttoken.html

I am using the consumer ke开发者_开发问答y and secret given to me by Yahoo. I am not specifying a callback URL. Instead, I set it to 'oob,' as suggested by the documentation.

What am I doing wrong?

Ok. Got it now. The Yahoo developer page has some screwy UI and the "--" at the end of my consumer key was not showing up.

Also, you don't need the quotes for oob and the signature method. Now it works fine.
