WebHotelier supports automatic launching of availability search by passing GET or POST parameters as displayed below. We strongly recommend of using POST (an HTML form) whenever possible in order to avoid appending query keys to the booking engine URL.

Usage

The only required parameter is CHECKIN. Please, choose to use either CHECKOUT or NIGHTS, never both.

Combine paramaters

The above parameters can be combined with Voucher Code, Booking Code, and Language Selection method parameters.

It is recommended that Date form fields should use a date picker widget in order to provide a user-friendly experience. A free and open-source datepicker is included with JQuery UI and can be easily integrated. Numeric parameters should be select box fields. Note that not all fields are required (e.g. rooms) and can be safely omitted.

We suggest matching the design of the WebHotelier's availability form for a consistent client experience. Please, do not include the booking engine inside an IFRAME. A frame busting technique is used to prohibit this.

⛔ CAUTION ⛔

Do not forget to replace example.reserve-online.net in the examples below with the real booking engine hostname.

If you don't know the hostname yet, please contact WebHotelier support.
