Can only comment on your first question…

> Where is the best way to get the different parts of the url?

The platform URL should be available as environment variable C8Y\_BASEURL.

See [here](https://cumulocity.com/guides/microservice-sdk/concept/#authentication-and-authorization): “[…]The Cumulocity IoT exposes the REST endpoint /user/currentUser. The microservice retrieves the Cumulocity IoT address from the `C8Y_BASEURL` operating system environment variable.”
