How it helps

SITA Type X Distribution Service provides the exchange of operational XML messages for companies that already have or are developing XML-based applications.

Because not everyone is adopting XML at the same time, we’ve made this service backward-compatible with Type B and older protocols. Our Type X service has switching, routing, and conversion capabilities. This means you can automatically send and receive Type X messages without worrying about compatibility with other messaging protocols and formats.

SITA Type X Distribution Service is a managed service based on the principle of ‘connect once and reach all’. It’s supported by SITA’s proven 24/7 service monitoring, offering global support at a local level.
