Creating and exposing APIs allows your web application to interact with other applications through machine-to-machine communication.

API creation frameworks

• Django REST framework and Tastypie are the two most widely used API frameworks to use with Django. The edge currently goes to Django REST framework based on rough community sentiment. Django REST framework continues to knock out great releases after the 3.0 release mark when Tom Christie ran a successful Kickstarter campaign.
• Flask-RESTful is widely used for creating web APIs with Flask. It was originally open sourced and explained in a blog post by Twilio then moved into its own GitHub organization so engineers from outside the company could be core contributors.
• Flask API is another common library for exposing APIs from Flask web applications.
