Summary

Let's pause for a minute to consider everything we have gone over in this chapter. You've installed Postman and already made several API requests. You have learned how API requests work and how to call them. I explained some basic testing considerations and gave you strategies that you can start to use right now in your day-to-day work. You also got to make calls to GraphQL, SOAP, and REST APIs and learned a ton of API terminology.

You now have some firm ground that you can stand on as we proceed through the rest of this book. I will take you deep into a lot of API testing and design topics and help you get the most out of Postman, but in order to get the most out of it and not feel frustrated, it would be good to make sure you understand the topics covered in this chapter.

Take a minute to ask yourself the following questions:

• Would I feel comfortable reading an article on API testing? Could I follow along with the terminology used?
• What are some basic strategies and approaches that I can use in API testing?
• If I was given an API endpoint, could I send a request to it in Postman? What things would I need to do to send that request?
• If I was given some API documentation, could I figure out what kind of API it was and send requests to it?

If you can answer these questions, you certainly have the grounding that you need for moving on in this book. If you are not totally sure about some of them, you might want to review some of the relevant sections in this chapter and make sure you have that solid ground under your feet.

You've learned a lot already! In the next chapter, we will dive into some of the principles of API design and look at how to use Postman to help put those principles into practice when creating an API.
