The best way to set up tracking in easyTableBooking is with a landing page. You will have to set up a landing page on your website, with the necessary tracking scripts.
When the landing page is set up, you can then redirect the guests to that page when a booking is made.
This is done in Settings -> Booking settings -> Confirm URL.
The redirection does not work with the iFrame implementation. If you use the iFrame, you will have to change to a JavaScript widget, direct link, or pop-up.

For tracking you can use the following parameters. These will be sent to the landing page:
BookingID = [id]
Guests amount = [pers]
Arrival date/time = [arrival]
Payment = [payment]
Currency = [currency]
LCID = [lcid]
TypeID = [typeid]
Type name = [typetext]
To set up multilingual you will have to create multiple URLs with the same structure. That URL will then be used in the system like this.
