Using web services
Template:Moodle 2.0This document explains how an administrator set up a web service for ordinary users.
Introduction
A user goes on his security keys page. He gets a security key (also called token). He enters the key on the external application accessing to Moodle. At any time, a user can reset the key if he suspects that it has been stolen. The key is complex, long and difficult to generate. This is the recommended authentication method for web service, and this document explains how to set it up.

A service is a group of web service functions. You need to know that Moodle tests if a user has the right to use a service. Moodle doesn't test if an user has a right to use a web service function. By default any user using the web service authentication method will be able to call a service. To restrict a service to some user only you need to select the Restricted users option. When this option is enable, by default no user can user this service.
