Anyone who develops anything knows that they need tools to test their product. Developing APIs is no different. In order to ensure that you are releasing something that actually works, you need to test your APIs by hitting the endpoints and validating the responses.
I’ve been using POSTMAN to do this task for me. It is a clean, free tool that lets you send requests to your API, with full control on what’s sent (headers, content) and shows the full responses. It also saves your history so you can test an endpoint without having to retype the parameters over and over again.
Give POSTMAN a try, and let me know if you are using something else.
