Docuware API Authentification

Hello,

I am trying to use Docuware APIs and the first step is to get the request token.  I want to use the Windows account connection as we have on-premise licensing. But it does not work. I have the error message "External authentication failed!" with status 400 Bad Request when doing a POST request with the following url (I am using the Postman collection) : 

<<server>>/DocuWare/Identity/connect/token

Am I doing something wrong?

Thanks a lot for your support,

Best regards

Hi Mélanie. Did You get any answer about this problem or have you figured it out?

Hi! We are struggling with NTLM login via .NET API and have tried the following methods with no luck. The first three methods always return the User running the IIS App pool, the others return an Error without description. Do you have any suggestions/ideas on how to properly log into DocuWare (OnPrem) via .NET API, with local Windows credentials.

ImpersonationLevel: None
IsAnonymous: False
IsAuthenticated: True
IsGuest: False
IsSystem: False
