Update facebook status via SMS

Question

Hello I am developing a SMS application for updating facebook status in PHP. I can collect username and password of user. I know it can be done by Status.set ,but how can I use the username and password and get the necessary session key and as such. Please help.

Answer 1

You'll have to use extended permissions (offline_access). The user will still have to authenticate with oauth, the most 'inobtrusive' way would be the Desktop Application route
