Pass NTLM with Postman

Is there a way to pass Windows Authentication with postman?

I have added this in header but still 401 Unauthorized.

Authorization: NTLM TkFcYWRtaW46dGVzdA==

As suggested by this link. I've encrypted as Unicode (UTF-16, little-endian) but of no use.

Any Ideas?

  • I don't think there is a way to do that. But, you are not alone in wanting it...

    [EDIT] As of the addition of this edit, Postman has NTLM Authentication in beta in their most recent release.
