Use cases

Package tracking API use cases.

A useful tracking integration connects parcel evidence to the order, buyer or operator who needs it. These guides cover different implementations: a storefront page, a supplier handoff, a TMS event receiver, and a seller import all have different failure modes.

Trace provides tracking and owned shipment records. Your application supplies platform integration, customer authorization and business rules. Each guide includes concrete examples, limits and a rollout checklist, rather than assuming a carrier catalog guarantees every parcel result.

Choose the first workflow to validate

Start with the customer question and the system that owns the tracking number. A shipping plugin, seller upload and carrier scan are different data sources. Model a separate parcel cycle, then decide whether an immediate lookup or monitored record fits your application.

GoalFirst building blockWhat to measure
Answer an order-status questionOrder-linked records and an authorized parcel viewSupport contacts per shipped order; age of verified data
Ingest a warehouse or seller fileDurable imports with per-row reconciliationCreated records and verified histories as separate counts
Route delivery problems to supportCarrier-fact alerts and labelled Trace inferencesUnresolved actions and evidence quality
Recover a receiver outageDelivery attempts, durable deduplication and deliberate replayRecovered business events without duplicate notifications

Use sandbox scenarios for the UI and developer guides for failure handling. Then qualify representative real shipments for your carriers before customer rollout.
