Postman Client gets 401 where Postman Chrome Extension does not

Hi-

I have been running into a bit of a weird issue. I am trying to use the PostMan client to hit a REST API. Using the client, I get a 401. If I take the exact same information and use the PostMan Chrome Extension, I get a 200. Reading the forums, someone mentioned that the REST API needs to have CORS enabled (because PostMan is basically a webapp), but I am a little confused as to how I would do that. Any ideas?

First, I would stop using the Chrome extension since it’s not supported anymore and would be incredibly hard to debug.

Secondly, CORS is enabled usually by the API your using, so are you the creator of this API?

Something must work. Check the extension for any missing headers you have in the Postman app.
What API are you trying to reach?

Hey Kyle-

Yes. I am the creator of the API. I was able to use the API successfully via the Chrome client with Interceptor turned off.

The API currently uses a header of Auuhentication-Token to validate the user. If I turn off authentication, the PostMan client works fine.

Seems like there is something behind the scenes that is preventing the authentication from going through.
