I am trying to create an app for Basecamp. I managed to connect and pull data using curl (Basecamp API using cURL and PHP). However this requires the users login data.
I would like to use OAuth2 with Basecamp as in https://github.com/37signals/api/blob/master/sections/authentication.md. Unfortunately there is 0 documentation on this and I couldnt find any sample code. I saw there are several OAuth2 libraries http://oauth.net/code/, but I have no idea what to do with them.
Can somebody please show me some php sample code of how I would authenticate a user using OAuth2 in php and than make a request to the Basecamp API?
Thank you very much in advance.
