CCXCon is a simple API serves as an interface between edX running instances and different MIT apps.
At a high level, it takes information from multiple edX backends, and produces a single data stream. Going the other way, it takes data along this same single data stream and will route it to the correct edX backend.
Implements the APIs as described here http://docs.ccxcon.apiary.io/
You can run the entire project through docker.
pip install docker-compose
docker-compose up
From there, you can visit the minimal web-ui at https://localhost.daplie.com:8077/ (which proxies back to localhost, but has valid certificates).
You can run the tests via the command docker-compose run web tox.
To be authorized to make requests to CCXCon, you use OAuth2. OAuth2 clients can be made in the django-admin. If you're doing server-to-server oauth (edX and teachers' portal cases), you'll want to create a user representing them, and an oauth app tied to that user. The Authorization type should be "Client Credentials". You can read more about that in the OAuth2 spec.
