Why can I acquire an access_token using oob but not when I provide a valid callback url?


Hi have have used many “working” examples to request a token and they all work using oob, but not when I use a url. I have a valid web site and callback url in my app settings.

here is my request text: "https://api.twitter.com/oauth/request_token?oauth_callback=https://exampleCallback.aspx.

and my header: “OAuth oauth_consumer_key=“123”, oauth_nonce=“5205BD1C”, oauth_signature_method=“HMAC-SHA1”,oauth_timestamp=“1407775490”, oauth_version=“1.0”, oauth_signature=“XXXXXXXXXXXXXXXXXXXXXXXX””


This issue was due to a typo in the Default callback url in the app settings. The url was invalid so the request received a 401 even though the url was correct in the request.
