![]() Install InterceptorĪs I previously mentioned, Chrome has security restrictions in place that limit POSTMAN ability to create requests with custom headers and Cookies (or at least that’s my take on it). Once installed head over to your Apps page and load up POSTMAN. So if you haven’t already got POSTMAN installed, head over to the POSTMAN site or download it directly from the Google Store. If you don’t use Chrome browser there are other tools similar to POSTMAN available (I’m a big fan of BurpSuite, something I may blog on another time). I didn’t find much help on Google or StackOverflow so after a bit of fiddling and complaining I managed to get it working and I thought it would be good to put together a blog post on how to setup the POSTMAN proxy.īefore we start it’s worth saying that POSTMAN is a Chrome application so you will need the Chrome browser installed. However, when I first started to use the proxy I found it a bit tricky to setup due to some security restrictions in Chrome that POSTMAN has to work around. Recently POSTMAN has been extended to include a proxy that will save a copy of each request you make in your browser, when enabled, and is extremely useful for various tasks such as rapidly creating collections of requests and modeling a web application. For those unfamiliar with POSTMAN it’s an app for Chrome that allows you to create HTTP requests for Web and API testing as well as save requests into collections for future use. I am very excited about what we have in store for the coming days.Since being introduced to POSTMAN a few years back it’s become one of the main tools I use in my day to day testing and it’s a cracking piece of kit for testing with a lot of great features to boot. You should also notice a big improvement in response render times.īig thanks to Prakhar, Arjun and Abhijit for their contributions for this update. The search feature has also been improved. JSON and XML responses are collapsible so that you can go through huge response bodies easily. Not just JSONView, we have also integrated the XMLTree library for improved XML response rendering. Integrating JSONView has been a big feature request, and finally it’s available inside Postman. Postman saves all your data locally inside IndexedDB. We have open-sourced Interceptor and you can find the code on Github. Note on security: The only entity that the Interceptor communicates with is Postman when then saves it to your history. Here is a quick video of how that ought to look like if everything is working for you: ![]() Browse your app or your website and monitor the requests stream in. Click on the Interceptor icon in the toolbar and switch the toggle to “on”ĥ. Install Postman from the Chrome Web Store (if you don’t have it already!)Ĥ. Here is what you have to do to get this working:ġ. ![]() Built on the Chrome platform, the feature works effortlessly across Windows, Linux, Mac and Chrome OS. If you have a web app for which you don’t have a collection built already, or you just want to debug the APIs that your app is using, this is going to be a huge time saver. You can filter requests according to the URL based on a regular expression. There are no code changes required either. ![]() This means you can debug your web apps’ APIs in real time! There is no need to install or configure a proxy. The Postman Interceptor can now capture requests directly from Chrome and save them to Postman’s history. We pushed an awesome new update to Postman just now with two big features.
