API

Application Programming Interface. Vertrag, über den zwei Softwaresysteme Daten austauschen.

Detaillierte Definition auf Englisch. Hospitality-Fachbegriffe (PMS, OTA, RevPAR, ADR) werden auch im deutschsprachigen Hotelbetrieb meist in der englischen Form verwendet.

An API (Application Programming Interface) is the formal mechanism by which one software system requests data or actions from another. In the hotel-tech context, API quality is the deciding factor in integration depth: a deep modern REST API exposes reservations, guest profiles, rates, and inventory with bidirectional updates and webhook callbacks. Legacy systems offering only periodic XML exports are integration-incapable for modern workflows.
