Hello. I've readed the documentation about web services, and it seems to be everything about setting up a web service ON moodle.
What I need, is to connect to an outside web service using REST.
When the users login I need to send a request to an external web service. In that web service occurs the autentication and the service send me back a JSON object with the information of the user.
Where can I look for some information relative to this problem?
Do I need to write this fromscratch?
