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:
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¶m2=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.
Health Checks
