Are there any user searches that do not trigger an API request?

If results are cached, another search with the same parameters will not trigger a new API call. More details on our cache can be found in the article: Cache

In addition to caching, there are also limitations in the partner configuration that may prevent an API request from being made for a search. These include:

• Route restrictions (specific airports, countries, continents, etc). For further information on route configuration, see our article Route Configuration.
• Market restrictions (integration enabled only for users in specific markets, e.g. UK)
• Date restrictions (for example restricted today’s bookings, long term bookings)
• Restrictions on passenger type or numbers (e.g: infant searches not supported)

Further information on missing content and search restrictions can be found on our page: Why my offers are not present in results?
