HTTP Post NTLM with Flow

I'm trying to connect to a webservice via Flow, and it needs an NTLM Authentications (returning a 401 message with WWW-Authenticate : Negotiate,NTLM). 

 

Does Microsoft Flow supports this type of auth ? 

 

Thanks.

Re: HTTP Post NTLM with Flow

Microsoft deprecated NTLM in favor of Kerberos due to NTLM security vulnerabilities. If you review the Authentication and authorization in Azure App Service and the Azure Functions HTTP triggers and bindings documentation, you'll see that NTLM isn't a supported out of the box method. However, you can Use a custom authentication for your application - but even then, I'm not sure NTLM would be supported or not.

If this is functionality you would like to see added to Flow or a Flow Template, please consider submitting it to the Flow Ideas page, where it can be voted on by other users, and tracked and commented on by the Flow team.
