The Stay Data API uses its own proprietary technology to connect to the majority of the property management systems. As such, we do not charge for any additional licenses or fees that the hotel has to pay to Impala. For more information on how we use our technology to retrieve data from the property management systems, please check out Connecting a Hotel to impala's API for each compatible PMS.
The one exception to this rule is Guestline, as they have a direct PMS integration with Impala. Guestline does charge a fee per room which the hotel will need to negotiate with Guestline directly. If you would like more information on any of our charges or integrations, please reach out to us via the widget or you can contact us at firstname.lastname@example.org.
