How to get the DocuWare Version via API?

You find the version inside the JSON, which you can GET from this endpoint: https://servername/DocuWare/Platform

How to use OAuth instead of Cookies?

.NET

Please update to the latest DocuWare NuGet Packages. Unless you create the ServiceConnection or Cookies manually, it should use OAuth as soon as you release with latest DocuWare NuGet Packages.

How to renew a session when not using App Registration?

  • Please try to log in again when you get an HTTP 401 Unauthorized Error or once the access token is expired.

  • Make sure to avoid an endless loop to not lock your account when credentials are wrong.

What is the difference between Access tokens and Login tokens? When to use Refresh tokens?

  • You get an Access token when providing correct login information to OAuth. It allows you to authenticate until the Access token is expired or until you log out.

  • Create a new session: If you are already logged in, you can retrieve a Login token and set a custom expiration. The login token can be used to log in without using username + password.

  • Keep a session alive: Refresh tokens can be retrieved when you are using the App Registration.
