Why publish your own API
Large agencies and OTAs prefer to book through their own platforms rather than log in to a portal. An outbound API lets them pull your hotels, transfers and packages into their search results in real time — so your inventory reaches customers you could never sign up individually.
What partners expect from it
- Clear documentation and a test environment.
- Fast search responses and accurate availability.
- Partner-specific pricing and markups.
- Stable booking, amendment and cancellation methods.
- Mapped hotel identifiers, so your hotels match theirs.
Example
A Thailand DMC publishes an XML API. Ten OTAs in Europe and the Gulf connect to it, and the DMC’s contracted hotels start appearing in their search results with partner-specific rates.

Is XML still used, or is everything JSON now?
Both. Many established travel APIs are XML (often following OpenTravel standards); newer ones use JSON. A distribution platform usually supports whichever its partners need.
