CarTrawler API integration
Car rental is the classic attachment sale: offered at the right moment after a flight booking, it converts at rates a standalone search never reaches. CarTrawler aggregates the suppliers to make that practical.

The attachment mechanics matter more than the inventory. Offering a car on the confirmation screen converts poorly; offering it two days later by WhatsApp, with the destination and dates already filled in, converts far better. The platform handles both.

CarTrawler integration questions#
Is car rental worth selling at all?
As a standalone product, rarely — the search volume goes to specialists. As an attachment to a flight or hotel booking you already own, it is close to free margin, because the customer is already yours and the dates are already known.
How does the post-booking offer work?
You configure the timing and the channel. A common pattern is a WhatsApp message a day or two after ticketing with the destination, dates and a prefilled search, which converts considerably better than an offer on the confirmation page.
Do transfers and self-drive work the same way?
Similar flow, different products. Transfers suit arriving passengers who do not want to drive; self-drive suits longer stays. Both attach to the same booking record.
