i am trying to implement a simple login functionality using yahoo oauth, but i am unable to get request token from yahoo.
I am posting to https://api.login.yahoo.com/oauth/v2/get_request_token with following header
[Authorization] => OAuth oauth_callback="http%3A%2F%2Flocal.ems.com%2Flogin%2Foauth1%2Fyahoo", oauth_consumer_key="dj0yJmk9dTNGbDdvaER6YUkyJmQ9WVdrOVlVbGtUMDlOTkc4bWNHbzlNQS0tJnM9Y29uc3VtZXJzZWNyZXQmeD02Ng--", oauth_nonce="OcbtUPhEekDp9h01XEfWXdJ27IN2LKKq", oauth_signature_method="HMAC-SHA1", oauth_timestamp="1393665596", oauth_version="1.0", oauth_signature="j7THh4NUKHvBmn8wv5P7ZnPEkAA%3D"
I am not sure what I am doing wrong here. The same request works perfectly fine for twitter.
The problem is that the yahoo response does not clearly specify what is wrong in my call. If I somehow know if any of the parameter that I am sending is wrong or there is some specific issue, then I am work to debug that issue. Any help would be appreciated.
