OAuth test server and help my slow brain understand what I'm doing.

Hi.

I've been tasked to integrate some financial data into our site. The
provider uses a 2 legged OAuth mechanism for the security.

I have my consumer key and secret and the service end point, but I'm at a
loss to even know if I'm doing anything right.

Does anyone have a script that uses 2 legged OAuth I can use to make sure
I'm doing it right and to be able to just substitute my keys and end point
as a test to the service I need.

Alternatively, if any one has done a 2 legged OAuth using pecl/oauth, then
please can you give me a few pointers!

Any help would be great!

Regards,

Richard.
