How to use Postman Interceptor

Question

Ever since I upgraded to Postman 0.9.6 I can't replicate user sessions because chrome doesn't allow postman to get user cookies. However, they have decided to "work around" this issue by created another plugin called Postman Interceptor that routes your postman request and grabs the user cookies. They wrote a blog post about this wonderful tool here: http://blog.getpostman.com/index.php/2014/02/11/postman-v0-9-6-access-cookies-and-restricted-headers-plus-better-testing/

However, I can't seem to figure out how to get this thing to work. I have been trying for an hour now, and it still won't see my request as a logged in user

Answer 1

This worked for me:

1. Install Postman
2. Install the Interceptor
3. Activate the Interceptor by toggling the switch:
   
4. Activate the Interceptor in Postman by clicking on the Interceptor Button on the top right (looks like a sattelite)
   

Answer 2

To save someone having to dig through all the comments on related questions, here's a quick overview of the state of Postman in 2018:

Standalone Postman (Current)

If you have a satellite dish icon you are using standalone Postman:

Postman Interceptor does not appear to work with the standalone Postman (as of January 2018).

When you turn the satellite dish on, you are starting a proxy (default port: 5555). If you update your browser and/or OS proxy settings to point to localhost:5555, the requests made through the proxy will show up in Postman, similar to how it worked with the old Interceptor.

You can read more about this feature here.

Postman Chrome App (Deprecated)

If you have a weird satellite thing icon you are using the old Chrome App:

This should work with the interceptor. See the instructions in nozzleman's answer if you are having trouble getting it to work.

tl;dr You need to use the Postman Chrome App if you want to use the Interceptor extension.

Answer 3

Make sure to turn the Interceptor on in chrome and proxy on in Postman. Also ensure install correct extension! Oddly, it seems there are 2 postman Interceptor:

1. Interceptor 1 <- Same name but not from getpostman.com
2. Interceptor 2 <- from correct source

Then it should work

Answer 4

The issue for me was that I had multiple Chrome profiles, and requests with a non-main profile wasn't working, even if the extension was enabled. Once I switched to the primary profile and ensured the extension was enabled there, it started intercepting properly.

Answer 5

For native app POSTMAN(windows, macOS or linux) make sure you have installed the INTERCEPTOR Bridge:
