Steps

  1. Define a canonical status enum for your application (e.g. PRE_TRANSIT, IN_TRANSIT, OUT_FOR_DELIVERY, DELIVERED, EXCEPTION, RETURNED)
  2. Build a mapping table from each carrier's raw status codes and descriptions to your canonical enum; consult each carrier's tracking API documentation for exhaustive status lists
  3. Ingest tracking events from carrier APIs or aggregators (EasyPost, Shippo) and apply the mapping at ingestion time, storing both the raw carrier status and the normalized status
  4. Flag events that do not match any mapping rule and route them to a review queue rather than silently dropping them
  5. Expose a single tracking endpoint in your system that returns the normalized status plus the latest carrier-provided description and timestamp
  6. Revisit and update the mapping table when carriers publish status code changes in their release notes
