Implement the DCSA Track and Trace v2.2 standard to build a carrier-agnostic ocean container tracking client

Steps

1. Download the DCSA Track and Trace v2.2 OpenAPI specification from the DCSA GitHub repository at github.com/dcsaorg/DCSA-OpenAPI; review the Event Structure Definitions and DCSA Industry Blueprint 3.0.
2. Identify the three primary event categories: Transport Events (vessel departure/arrival), Equipment Events (gate-in/out, load/discharge), and Shipment Events (booking confirmed, B/L issued).
3. For each carrier integration, obtain API credentials from the carrier developer portal (Maersk, Hapag-Lloyd, etc.) and confirm which DCSA T&T version they implement; map any carrier-specific event codes to DCSA equivalents.
4. Build a normalised event ingestion layer that maps carrier API responses to the DCSA event schema; store eventType, eventDateTime, eventClassifierCode, and location fields in a canonical format.
5. Implement the DCSA Subscription Callback API v1.0 on your server to receive push notifications from carriers that support server-to-server push; fall back to polling for carriers that do not.
6. Validate your implementation against the DCSA conformance test suite available on GitHub before going live with each carrier integration.
