We now have everything we need to start creating out API endpoints. In this section, we are going to create endpoints for every method that we implemented in the Order manager.

For some of these endpoints, we are going to use the Django REST Framework. The advantage of using the Django REST Framework is that the framework includes a lot of out of the box features. It has different authentication methods, a really robust serialization of objects, and my favorite is that it will give you a web interface where you can browse the API, which also contains a large collection of base classes and mixins when you need to create class-based views.
