The first entry is the booking being recorded. Each following one is a change, with how it was learned: `API` when a read or an action of yours found it, `WEBHOOK` when the travel provider reported it, `POLL` when a periodic check did. The trip is brought up to date with the provider before the answer, so a change the provider already made shows up as a fresh entry. Empty while the trip is still being created. Visible to an organization admin and to the users the trip carries, like the trip itself. ## OpenAPI ````yaml /api-reference/travel.openapi.json get /realms/{realmId}/organizations/{organizationId}/trips/{tripId}/history openapi: 3.0.3 info: title: Travel version: 1.0.0 description: >- Portão 3 travel API. Every endpoint requires a bearer token in the Authorization header (Authorization: Bearer ) unless its page states otherwise; see the Authentication guide. That requirement is not repeated per endpoint. Generated by tools/openapi from code (routes + security) and the hand-written spec (request/response bodies). Passenger directory, trips and the search proxy (air/hotel/bus/vehicle). Every route validates path, query and body through a zod Input class (`travel/src/domain/*/input`), which documents its parameters and body; responses are the named interfaces in `travel/src/domain/*/response.ts`.
