Review

At this point, you now know how to build an API that:

• Handles multiple kinds of requests
• Can handle a request body
• Can format both successful responses and error responses

And in this lesson, you also learned how to:

• Test your API using Unittest
• Build your API using Test-Driven Development (TDD)

By taking this approach in your future development, you'll be able to produce applications in a way that catches issues prior to putting them in front of the user, and in a way that makes it easier to maintain that quality as the app grows.

Next, we'll be looking at how to make your API usable by others, through writing API documentation. Onwards!
