Sixt API integration for travel booking sites

Sixt is a German car rental company with its own branches across Europe and North America and franchise partners in many other countries. PHPTRAVELS has no ready-made Sixt connector, so there are two honest routes: sell Sixt cars through a car rental aggregator that already runs in the cars module, or have our team build a direct Sixt connection for you.

  • Through an aggregator
  • Or a custom build
  • Cars module
  • Your own agreement

Two routes

Pick the route that fits your volume

Most agencies start with an aggregator and only build a direct connection when Sixt becomes a large share of their car sales.

Route A in practice

Sixt cars in your search results

Through an aggregator, every car keeps its rental brand. Customers can filter by brand, and support knows who will hand over the keys.

FAQ

Sixt integration questions

What agencies ask before they add Sixt cars to their site.

Talk to sales

No. There is no built-in Sixt connector. You can sell Sixt cars through CarTrawler or Discover Cars where they carry them, or we can build a direct Sixt connection as a custom integration.

No. PHPTRAVELS has no partnership with Sixt. Any agreement, API access and rates for a direct connection come from Sixt to you.

Not always. It depends on whether the aggregator carries Sixt at that location and on your agreement with the aggregator. Where it does, the car shows the Sixt name.

It depends on the API Sixt provides and the scope you need. Once we have the documentation and test access, we send a fixed scope and timeline.

Yes. A direct Sixt connection can run beside CarTrawler or Discover Cars in the same cars module, with your own markup rules for each source.

No. If you run your own fleet and branches, see the car rental system page, which covers your own inventory, branches and deposits.
