Moodle 2.0

This 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. This document explains how a Moodle administrator can set it up.

Enable the web service in Moodle

  Settings block > Site Administration > Advanced features

  Check Enable web services option and Save Changes

Enable a protocol

  Settings block > Site Administration > Plugins > Web services > Manage protocols

  Enable the desired protocol (SOAP, REST, XMLRPC, AMF, ...)

Enable capabilities to users

for create token

you need to set "moodle/webservice:createtoken" capability to the users

for protocols

you need to set the activated protocol (webservice/rest:use, webservice/soap:use,...) capability to the users

Create a service with funtions

  Settings block > Site Administration > Plugins > Web services > External Services
  Click on Add new custom service

Add new custom service page

A service is a group of web service functions. You need to create first the service then add the function. When you create the service do not check "Authenticated users", we want all users (only the one with "moodle/webservice:createtoken" capability) to be able to use the web service. If you want you can select a required capability. Any user access a web service will be checked against it. It is just an additional and optional security layer for your own usage.

  Enter a name, check enable
  Click on Save changes

Add a function to the service

  Settings block > Site Administration > Plugins > Web services > External Services

  Click on the Functions link for the newly created service

Service functions page

  Select Add function operation, then select a function and Save changes

Users visit web service page to get auto token

Congratulation, the web service are set up. The users will now go on their profil block and access their security keys. The first time a user access the "security keys" page, his key is created.
