![]() Thus, a single collection can be used with various configurations. With Postman, we can create more than one environment. The Postman console allows debugging test steps. Postman can be integrated with Newman or Collection Runner which allows executing tests in much iteration. Postman can be integrated with the continuous integration and either continuous delivery or continuous deployment (CI/CD) pipeline. Postman can be used for test development by addition of checkpoints to HTTP response codes and other parameters. Postman is capable of building multiple API calls like SOAP, REST, and HTTP. Users can make a collection of API calls which can have varied requests and subfolders. Postman allows easy maintenance of test suites with the help of collections. Postman can be accessed very easily by logging into your own account after installation on the device. Postman can be used very easily by just downloading it. ![]() Postman comes without any licensing cost and is suitable for use for the teams with any capacity. Postman has a huge user base and has become a very popular tool because of the reasons listed below − It can build multiple HTTP requests – POST, PUT, GET, PATCH and translate them to code. It has a graphical user interface (GUI) and can be used in platforms like Linux, Windows and Mac. Postman has the feature of sending and observing the Hypertext Transfer Protocol (HTTP) requests and responses. It can be used to design, document, verify, create, and change APIs. It is a tool for testing the software of an API. Postman was designed in the year 2012 by software developer and entrepreneur Abhinav Asthana to make API development and testing straightforward. We require an API whenever we access an application like checking news over the phone, Facebook, and so on. Thus, an API is a collection of agreements, functions, and tools that an application can provide to its users for successful communication with another application. API acts like an interface between a couple of applications and establishes a connection between them. The broader development community has published some useful tutorials for setting up a proxy server on various operating systems.Postman is an Application Programming Interface (API) testing tool. Open your device’s web browser or your application and you will start seeing HTTP traffic passing through the app or the browser. You are all set! Head over to the Postman app, and you will start seeing the network calls listed under the History tab of the sidebar. Set the proxy IP address of your device (an iPhone in this example) to the IP address you obtained from your system and port 5555. Set the port with the port you established in Postman in Step 1. Set the IP address with the IP you retrieved from your computer in the second step. Open the wireless settings of your mobile device and update the configuration of the wireless connection to use HTTP Proxy. Step 3: Configure HTTP proxy on your mobile device The IP address of your system will be something like the example here 192.168.0.101. On OS X, the computer’s IP address can be found in System Preferences > Network. This will cause all your requests to be captured and stored in the History sidebar panel. In this case, let’s keep it at the default port 5555. Keep a note of the port mentioned in the proxy settings. Open the PROXY SETTINGS modal in the Postman app (MacOS) by clicking the icon in the header toolbar. ![]() To get started, make sure your computer and mobile are connected to the same local wireless network. In this tutorial, we will use Postman’s proxy feature to inspect HTTP communication going out from your phone. In this scenario, the Postman app is the proxy, and you can inspect HTTP communication going out from your phone like in the following example, and log all network requests under the History tab of the sidebar. Similar to the Interceptor Chrome extension, the Postman app proxy also INTERCEPTS and captures your requests. The server returns a response through the Postman proxy back to the client.The Postman proxy captures the request and forwards the request onward to the server.The Postman app listens for any calls made by the client app or device.Postman has a proxy in the Postman app that captures the HTTP request. ![]() Note: for the Postman native apps, request captures over HTTPS will not work if the website has HSTS enabled. You can use the built-in proxy in the Postman native apps or use the Interceptor extension for the Postman Chrome app. Postman gives you tools to see and capture this network traffic easily. In some cases, you might discover APIs that are not even documented. ![]() If you are using APIs to build client-side applications - mobile apps, websites or desktop applications - you might want to see the actual HTTP request traffic that is being sent and received in the application. ![]()
