Question

I’ve read all the threads about simiular issues on SO and elsewhere, and none of them have solved my problem.

I’m using Twython as a wrapper around the API. I’ve tried setting oauth_callback EVERYWHERE. Using the internal mechanism in Tython (which is done by setting callback_url on instantiation), by manually modifying the auth_url and appending the argument by before redirecting the user, etc. I’ve tried deleting and recreating both new twitter apps and new twitter accounts, to no avail.

Whenever I redirect the client to twitter, the correct oauth_callback is ALWAYS visible in the url along with the oauth_token, but the api always ignores this argument and overrides it with the url in the settings of my twitter app (both are under the same domain). I have tried figuring this out for several hours and I’m at a dead end. I’ve seen this work before and I’ve done it plenty of times, so I don’t know what could possible be going wrong.

It’s strange– even if i set the callback to ‘oob’, which ought to trigger the PIN workflow rather than a callback, this argument is EVEN THEN ignored. Any ideas why?

You specify the oauth_callback value when you get a request token as specified in OAuth 1.0a. In 1.0 it you could pass it along with with the user when they go to twitter.com but was changed for security reasons. You can read more about it in the /oauth/request_token docs.
