Breeze APIs
Our JSON and NDC/XML APIs run on the same backend service. They are mostly similar. We recommend using our JSON API, as it includes useful features that are not allowed by IATA's schema.
- JSON API — our own schema under
/json/{version}. Recommended for new integrations, with some functionality beyond what the IATA definitions allow. - NDC/XML API — IATA NDC schema under
/ndc/{version}.v21.3is unsupported. - Differences between them if you need help choosing.
Visit our dedicated page to learn about our release schedule that applies to both APIs.
