At the start of this course, you’ll be introduced to a handful of important practices and principles for designing and building APIs that are robust, reliable, and resilient. You’ll also acquire skills in a wide range of developer tools, including tools for design, documentation, building, testing, security, and deployment. 

You'll learn the best practices for modeling an APIs lifecycle using Donald Norman’s action lifecycle. Then, you’ll learn how to use the sequence diagram for designing APIs and describing them using ALPS. For sketching an API, you will learn about Gehry's sketches. You will also cover OpenAPI and SwaggerHub for API mocking. Moreover, the usage of DARRT and NodeJS will be covered for building APIs. You'll finish with learning how to use the Postman for testing APIs and then deploy them using Heroku.

By the end of this course, you will have an in-depth understanding of how to make fully functional efficient APIs from its inception to its deployment.

Design and Build Great Web APIs

In this chapter, we covered the concept of generating prototypes for our API as a final step before committing resources and time to writing the actual code to implement our design. For our API work, we used OpenAPI Specification (OAS), formerly known as Swagger, to build up our working prototype in detail from our initial design. We learned how to use OAS document elements such as `info`, `components`, and `paths` to build up the definitions of our endpoints, as well as how to use `parameters`, `requestBodies`, and `responses` to fill in the details of each API URL and method in our prototype.

Finally, we learned to use the SwaggerHub Editor to do our live editing, generate our mock server for prototype testing, and generate technical API documentation. We also learned how to use the external documentation generator ReDocly to quickly and easily create interactive API documentation from our OAS file.
