Why it matters

Transaction concepts describe how a metasearch click becomes a downstream booking experience. Without context-preserving links, durable click identity, booking lifecycle events and reconciliation, search performance becomes disconnected from actual commercial outcomes.

What does it look like in practice?

A metasearch click ID travels through the deeplink, returns with booking events and is reconciled through cancellation/stay states. Breaking this lineage creates commercial attribution gaps.

Implementation questions

  • Is search context preserved on the landing page?
  • Is there a durable ID from click to booking?
  • Are booking lifecycle events idempotent?
  • Is provider state reconciled with internal state?

Common mistakes

  • Treating a generic landing page as successful handoff
  • Treating unknown booking state as failed
  • Counting replayed conversions twice

Where does it appear in the travel stack?

Booking Engine commonly appears across transaction layers. Its implementation should make source-of-truth, identity, freshness and transaction-ownership boundaries explicit.
