Testing is a critical stage in the development of any web API. Manual testing allows you to understand the ins and outs of your API’s functionality and catch issues before they reach production. One of the tools you can use is Postman, it simplifies the process of testing web APIs by providing a user-friendly interface and a suite of features designed to enhance your testing efforts.

Key Features of Postman

• Send requests to the API and view responses.
• Create and manage environments for testing different stages of development.
• Document the API for easy sharing and collaboration.

To help you get started with API testing, there is a hands-on YouTube tutorial that covers the following steps:

1. Tool overview - Learn basics of what you can do while testing your APIs.
2. Sending GET request - Make your first GET request.
3. Sending POST request - Add a JSON body and do a POST request.
