REST API Client for Open edX

The REST API client for Open edX REST API allows users to communicate with various edX REST APIs. It is based on https://github.com/edx/edx-rest-api-client, whith a few differences:

• It does not depend on Django
• What is called 'the client' in edX's version is now called 'session'.
• As the edX's version relies on Django's cache, now the token is stored in memory under the scope of the session object
• The client here encompasses the session, and one function per REST API entry point

Part of the code is also taken from Opencraft's implementation of the openedx client.

Testing

$ make validate

Usage

The OpenedxRESTAPIClient object starts a session with the LMS and provides methods to access the Open edX endpoints.

from openedx_rest_api_client.client import OpenedxRESTAPIClient

client_id = 'my_client_id'
client_secret = 'my_client_secret'
lms_url = 'https://lms.example.com'

# create client
client = OpenedxRESTAPIClient(lms_url, client_id, client_secret)

# get a list of all courses
courses = client.list_all_courses()
