API Tester is a mobile app that lets you perform HTTP calls of various methods. You can use the most basic methods, such as GET, POST, and PUT, but you can also apply DELETE, HEAD, OPTIONS, COPY, LINK, and LOCK. You can also test using custom headers and query parameters.

HTTP Methods testing is a critical aspect of API testing, and the API Tester mobile app makes it easy to test all available methods. The App has various features to make testing more accessible, including:

  • A Method overview that lists all methods and their parameters.
  • A complete list of available methods with descriptions and examples.
  • A button to quickly create a new request.
  • The ability to save requests for later use.
  • A history of all executed requests.

How to Send Requests and Receive Responses in API Tester?

API Tester lets you easily send requests to different servers. You can also test your requests in real-time to see how they respond.

To start, open the API Tester app on your phone. Click the “Create Request” button to create a new request. The fields in this window are essential:

Request Type: This tells API Tester which requests you make. You can choose from a few options: GET, POST, PUT, DELETE, etc.

URL: This is the URL you want to access in your application or server.

Test GET, POST and PUT requests using API Tester.

If you know about API tester and want to see how we use the API tester app to create various requests using get post put and delete methods, then stay with me.

This guide will use to try various HTTP methods. Once you open their page, you will get a list of requests, responses, and response polls. We start with the GET method by creating a request using an API tester mobile app.

The GET method retrieves information from a given server using the provided URL. Let us try it out. Then we need to click “Create new request” button, choose the GET method from here, and then give it a proper title. Then, we can enter the URL; in this case, the URL is an, and then we must pass on the query string parameter, which is page equals 2.

In this example, we have one query string parameter, although using several string parameters is also available. If we run it, we will get the 200 OK success status response code which signals a successful request.


In this tutorial, we covered the essentials for getting started with API Tester. We learned how we may make a basic request and then examine and validate the response which we get back from the server.
