Once installed you should see an icon that looks like the one below in the top right corner of the browser which indicates Interceptor is installed

We want to install Interceptor which you can grab from the POSTMAN site or again download directly from Google Store. So there is an extension for POSTMAN to workaround these restrictions which is an app in it’s own right called Interceptor. 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).
Postman interceptor header how to#
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.
When we send our request with those custom headers, we can see right in the event logs our custom header.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. We can also see that we can set our own custom headers using the Headers table. We were able to see all the headers that were hidden that are generated by Postman itself. In review, we had a POST Request where we wanted to send custom headers. When we add authorization through the Authorization tab, we can see that it's added as a hidden header, but if we wanted to do that manually, we can turn that off or we can add the authorization header and then set our value which we can then post and see that it gets sent with our request. If we wanted to add our own custom headers, we can use this Headers table and add a Key-Value pair, so if I wanted to add a key of test and a value of true, I can now send my request, and I can now see that inside of my Event Headers, I have test equals true. Because we're setting our body with the type of JSON, it automatically includes Content-Type of application/json, and because we're sending this from Postman, it also includes a User-Agent of PostmanRuntime. Currently, we don't see any headers there, but if we click hidden, we can see all the ones that are automatically generated and included with Postman. If we wanted to modify the headers or simply see what's being sent, we can click the Headers tab inside of Postman.

Because on the code we're console.logging out parts of the event including the Path, HTTP Method, Body, and Headers, we can see in the terminal that we can see the Path as /post, the Method as POST, the Body of test equals true, and we also see all the default Headers that are set in Postman. We can see this working, and if we hit Send, we can see that the status is 200, which is OK. Colby Fayock: We're going to start off with a new request in Postman, where we're posting to an endpoint called post, the data test equals true.
