Send request using NTLM Authorization

[carlo-andreoli]

Hi,

is there a way to use the package to send request using NTLM Authentication (username & password)

Thanks in advance.

Can you provide me with a link to the specification?

I don't have any specification, simply what I was trying to achive is to execute this request made on postman with NTLM authorization:

Got doesn't have built-in NTLM support. NTLM requires a multi-step challenge-response authentication process that doesn't fit well with Got's architecture.

Your best options are.

Use a dedicatd NTLM library like @node-ntlm/httpreq:

import {ntlm} from '@node-ntlm/httpreq';

const response = await ntlm({
	url: 'https://example.com/api',
	username: 'username',
	password: 'password',
	domain: 'DOMAIN' // Optional
});

console.log(response.body);

Use a local NTLM proxy:

Set up a proxy like CNTLM or Px to handle NTLM authentication locally, then use Got through the proxy:

import got from 'got';
import {HttpsProxyAgent} from 'hpagent';

await got('https://example.com/api', {
	agent: {
		https: new HttpsProxyAgent({
			proxy: 'http://localhost:3128' // Your NTLM proxy
		})
	}
});

The dedicated NTLM libraries are your best bet since they handle the complex authentication handshake that NTLM requiers.
