[Download the FIX 5.0 SP2 application dictionary](/fix/order-entry/FIX50SP2.xml) and the [FIXT 1.1 transport dictionary](/fix/order-entry/FIXT11.xml). Use the pair for this API; order entry and market data have separate application dictionaries.

Application messages carry market data and trading requests and reports using FIX 5.0 SP2. Field presence describes what must be sent to the exchange and what the exchange sends. Session messages manage the FIX session using FIXT 1.1, beginning with [Logon](/api-reference/fix/session-messages/logon). Both levels use the shared [header and trailer](/api-reference/fix/header-and-trailer).
