Core integration layers
The design centers on the real chain from Amazon data intake to internal execution and auditability.
Amazon SP-API intake layer
Retrieve authorized order-related business data and control access within the approved scope.
Application-processing layer
Handle parsing, task dispatching, state changes, retries, and operational rules.
Database and cache layer
Store master data, order status, audit fields, and queue state for frequent reads and writes.
Warehouse execution layer
Coordinate picking, packing, shipping, tracking return, and exception-resolution workflows.
Carrier / 3PL connection layer
Synchronize tracking numbers, carrier updates, outbound feedback, and fulfillment exceptions.
Logging and governance layer
Record access events, permission changes, exports, errors, and security-relevant activities.
Design principles
The goal is to support a real warehouse workflow while keeping the public explanation and privacy posture accurate.
Minimum necessary data
Request only the data fields needed for order synchronization, fulfillment, and customer support.
Reliable and traceable
Use retries, alerts, manual fallback, and audit logging for operational resilience.
Separated access boundaries
Keep operations, warehouse, support, and admin roles inside distinct permission scopes.
Public consistency
Keep the website, privacy pages, and public data-handling explanations aligned with the real operating model.
Need a public-facing integration explanation that matches the real system?
We can organize the website, privacy pages, and security-compliance language around your actual deployment and fulfillment model.
