Traum-Ferienwohnungen.de is a vacation rental marketplace and booking portal focused on “direct from host” listings across Germany and Europe. For professional hosts and agencies, the Traum-Ferienwohnungen Customer API provides a REST interface to manage listings and operational data so that manual maintenance of calendars and content is no longer necessary.

Using the Customer API, PMS/channel tools can automate core listing actions such as keeping availability up to date, reducing double bookings, and streamlining day-to-day portfolio management. The API is positioned as free to use for customers after registration via an account manager or support, with technical documentation available online and a dedicated API support email for integration questions.
