I want to send some extra parameters to twitter's oauth/authorize endpoint (along withoauth_token) and get them back as it is in the callback request (along with oauth_token and oauth_verifier).
For example:
request(extra parameter - app_name):
https://api.twitter.com/oauth/authorize?oauth_token=FxHxpekZK8VVfNRr38i2WKJskIZY3Hj7&app_name=myTwitterApp
callback request should be(extra parameter returned as it is - app_name):
http://www.example.com?oauth_token=FxHxpekZK8VVfNRr38i2WKJskIZY3Hj7&oauth_verifier=Vq0yq2LRUBybevnjGvXyUOBPWH9Ew9DY&app_name=myTwitterApp
Please let me know if this doable in twitter as it is in Google and Facebook.
Asked this question on twittercommunity and got the answer. The trick was to add the extra parameters in the callback url itself while obtaining the request token.
