NexSIS API Introduction

MoodleUS NexSIS API is a RESTful API that facilitates realtime integrations between Moodle and 3rd party systems, especially management information systems such as student information systems (SIS), human resources information systems (HRIS), and customer relationship management systems (CRM).

Why not Moodle core external services?

It is true that Moodle comes with external services available out of the box. These work well for their specific purpose; however, we have found that they are neither well geared towards nor designed for integration with a management information system. For example, they do not facilitate bulk operations, and they operate on the unique identifiers of the Moodle system.

MoodleUS has designed the NexSIS API from the ground up. Some of the key differences with Moodle's built-in external services are:

Simpler, more streamlined API calls geared towards a management information system
Facilitation of both individual and bulk operations
Operations performed on the unique identifiers of the external system

Requests

Authentication

Header authentication example:

GET /enrol/nexsis/api/index.php/ping HTTP/1.1

Authorization: Bearer {token}

Host: example.moodle.com

Accept: */*

Query parameter example:

GET /enrol/nexsis/api/index.php/ping?token={token} HTTP/1.1

Host: example.moodle.com

Accept: */*

NexSIS uses API keys to allow access to the API. You can enable the API and generate an API Key in the plugin's Moodle administration area.

NexSIS expects for the API key to be included in all API requests to the service. You have the option of passing the key in an Authorization header or as a query parameter named token.

The authorization header must follow the following format, where {token} is your API key:

Authorization: Bearer {token}

You must replace {token} with your API key.

HTTP Verbs

NexSIS API is a RESTful API and operates using the standard HTTP verbs. A brief description of each follows:

Verb	Description
GET	retrieve a resource
POST	create a new resource
PUT	update a resource
DELETE	delete or remove a resource

NexSIS considers the management information system to be the master record of some resources. Therefore, those resources do not support the POST verb. Since the resources already exist and have a unique identifier, and Moodle just has a copy of the resource, both Moodle creation and update use the PUT verb.

Sending Data

Example request (JSON):

PUT /enrol/nexsis/api/index.php/enpoint HTTP/1.1

Authorization: Bearer {token}

Host: example.moodle.com

Accept: */*

Content-Type: application/json

{

"param1": "value1",

"param2": "value2",

}

Example request (URL-encoded):

PUT /enrol/nexsis/api/index.php/enpoint HTTP/1.1

Authorization: Bearer {token}

Host: example.moodle.com

Accept: */*

Content-Type: application/x-www-form-urlencoded

param1=value1&param2=value2

When sending data to the API, you can choose whether to send data in JSON or in URL-encoded format.

When sending JSON data, be sure to set the Content-Type header to application/json.

Responses

Unless otherwise noted or specified, all responses from the NexSIS API are JSON encoded format.
