Looks like a POST request is more or less straightforward to understand once you’ve managed to decode a GET request. Once installed, head over to Requestly's Mock Server and click on Create new mock API. We’ll then inspect the network tab in the chrome dev tools to figure out how Postman communicates with the actual API endpoint that we test.įirst, let’s quickly set up a mock server with Requestly - an open source browser extension that fast tracks your web debugging process. We’ll work with two simple requests today - a GET request and a POST request. If you’ve ever used Postman before, this should appear familiar. We'll then analyze the behaviour of Postman using the network tab of our browser's DevTools, allowing us to deconstruct the application's operations. To do this, we'll use Requestly Mock Server to create a couple of dummy API endpoints. We will delve into the inner workings of Postman's web application and explore what transpires when you use it to test your HTTP requests. In this article, we will learn how Postman Web works and HoppScotch indeed works very similarly. However, after the success of the HoppScotch Open Source Web-based Rest API client, Postman also launched their web-based API client.īut have you ever contemplated how Postman operates behind the scenes? Fortunately, debugging web applications today is a breeze, as the comprehensive Chrome DevTools enable you to deconstruct any application on the web. It started with a Chrome extension which later got deprecated, so they moved into the desktop app. Postman is an exceptionally well-regarded REST API client that developers rely on to construct and evaluate their APIs.
