Changelog - July 2025

✓ We’ve released several enhancements to improve performance, clarity, and usability for car rental search results.

Car rentals

Increased maximum page size

| Update | maximum_results=500 | cars/search endpoint | version 3.1

We have increased the maximum allowable page size for the /cars/search endpoint from 100 to 500 results per page.

Partners can now request up to 500 results in a single page using the maximum_results parameter (e.g., maximum_results=500).

  • Requests exceeding 500 will return an appropriate 4xx error.
  • Pagination metadata (e.g., next_page) works as expected with larger page sizes.
  • If fewer than 500 results are available, all results are returned in a single page.
Benefits

Reduced client-side timeouts, fewer API requests, and more efficient data aggregation.

This change does not impact partners who continue to use smaller page sizes.

New response field – search token in /cars/search

| New | search_token | cars/search endpoint | version 3.1

We have introduced a new field, search_token, to the /cars/search response.

  • When supplied, the API will use the stored search context associated with the token, reducing the need to resend the entire search payload (such as route, filters, or booker country).

How to use it:

  • The first search request includes a search_token value in the response.
  • Include the search_token in subsequent requests to cars/availability and orders/preview endpoints (from v3.2) instead of resending the full search criteria.

Note: This field is only useful for Demand API v3.2

New response field – insurance package in /cars/search

| New | insurance_package | cars/search endpoint | version 3.1

We have added a new field, insurance_package, to the /cars/search responses.

This field indicates the level of insurance included by the supplier with each car rental product (different from optional insurance extras).

  • basic: Standard supplier insurance (may involve higher excess).
  • inclusive: Enhanced insurance coverage included.
  • zero_excess: Full coverage with no excess liability.
Benefits

Enables partners to show clear, upfront insurance details to customers.

These enhancements are backward-compatible. Partners not using the new parameters or fields can continue to integrate as before.
