Logistics & Integration Systems

Shipment creation, carrier integrations, tracking, returns and the delivery lifecycle.

01 · Problem

Every carrier has its own API, status codes and failure behaviour, yet the platform must offer sellers and buyers one consistent delivery process.

02 · Approach

Hide carrier-specific details behind a shared integration contract, map status updates onto one lifecycle, and make outbound calls resilient to retries and transient errors.

03 · Technical challenges

  • Mapping each carrier's states onto one model
  • Tracking updates that arrive out of order or more than once
  • Keeping returns aligned with order and finance flows

04 · Value delivered

An integration layer where a new carrier can be added without touching the core flow.
