Adding oauth_callback causes 401 Permissions Err


Everthing works wonderfully - except when I try to apply the oauth_callback parameter so that I can override the one that I added when I created my application.

Remove the oauth_callback parameter and it works as expected, otherwise…no mater how I encode the callback url…401 Un Authorized Error.

Help? Thanks!

I am constructing the headers authorization values as defined @
