Hi @Cobra7 !
The cloud applications needs an accessible URL to provide the authorization code in order to get the bearer token.
If it is a single test, you can put any invented URL and get the code although the redirect result in a failure in the browser, but you will find in the URL the code, like:
http://new.url.not.exists.com/?code=f2f25f7c8be5d9f5
In a real environment the allowed callback URL should be public and should be managed by your application, to get the code and perform the authorization, the flow is described in https://docs.lansweeper.com/docs/api/authenticate, in authorization-and-authentication-sequence section.
