Web services API
From MoodleDocs
Overview
The Web services API allows you to expose particular functions in your module (usually external functions) as web services.
Once you have done this, your functions will be available to admins to configure as part of their Web services over a given protocol like XML-RPC, REST or SOAP.
You must create two files to expose web service functions:
- plugin/db/services.php - the declaration of your web service functions
- plugin/externallib.php - the functions implementation
services.php
- This file is located in the db folder of your plugin
- It contains an array contains declaring your web service functions. Each of these declarations reference an external function.
externallib.php
- This file is located at the root of your plugin.
- This file is composed by a class that contains the external function referenced in services.php
Example
Have a look to the web service template. It is a simple hello_world function. It also contains a test client in the folder /client.
