request_token is expiring after a every call.

Hello,
After getting a request_token from URL I am able to make first call. But after the first call I always get ('Authentication failed', 'Invalid session credentials') error.

Is this is a bug or it is a expected behaviour. If it then please let me know how to maintain the session as it is not appropriate to generate request_token for each API request.

my API_KEY is lbz0bpyt27250q51

@muke5hy Request token can be exchanged for access_token only once. The program should store the access token in a file or a database.

@vivek Thank you for the reply. I was doing it wrong. May I also know what is time frame for this access_token.
