Question

I’m very new in oAuth.

I’m writing a desktop based windows client for Twitter APIs. When I’m using value “oob” for oAuth.CallBackUrl. At the time of authorization, I get a PIN (i.e. 75940xx). please help me finding, how shall I use that PIN in my application code to be able to fetch data from Twitter.

An example would be much appreciated.

There are 3 main steps in OAuthentication. By the sounds of it you have completed the first two. See below for summary of steps.

1. Request Token Key and Token Secret
2. Use Token key to grant application access to data. (if this is successful the user will be provided with a PIN
3. The PIN is then used to exchange the Token Key and Token Secret for an Access Key and Access Secret. The Access Key/Secret are used to access the users data

For a more detailed OAuthentication flow see this link. I would also recommend reading the OAuth RFC. I hope this has been helpful.
