I am trying to access a [Northwind Service] (http://services.odata.org/V4/Northwind/Northwind.svc/Categories) but my request is getting intercepted by Zscaler.

I access the same link from Chrome or IE it works fine. I am expecting POSTMan to do the same..!

Same issue here. Hope for a fix/way to authenticate Postman with the zscaler. Version 4.10.7 Win7, win / x86-64 Chrome 58.0.3029.110 Interseptor-Status doesn't matter (tried before and after installation) Screenshot would show the exact same message as the reporter.

Inner-network calls on Postman work just fine, anything else (for example: google) can't be processed, as the postman does try to show the Website of Zscaler, but obviously can't show it completely and cannot allow authentication. Chrome itself already is authenticated.

As far as I understood, Zscaler is placing one (or more) cookies which signal the browser is authenticated. In Chrome I could find these cookies: image If one were to delete all cookies, Zscaler would force an authentication by the company's method before allowing calls to the internet again. Maybe that's happening with Postman.

Postman does not support opening dilog boxes like browsers But it does support cookies!

Postman Chrome App

It can use cookies from the chrome browser. You need to use postman-interceptor (install the extension in chrome and then turn it on in the Postman app) image @junejosheeraz @taschana Since this will automatically use cookies from the browser, no extra action is needed. This should fix it.

Postman native Apps

For those you are using native apps, they can copy their cookies from the browser to the Postman app

  1. click on cookies image
  2. edit an existing cookie image

let me know if this works

Postman-Interceptor extension was missing. Once installed and enabled in PostMan (as described above for extensions) it works like a charm. Thanks.
