• Shopify order events (create, paid, canceled, address updates) are routed to Manhattan OMS via API or middleware, with idempotency keys to prevent duplicate submissions.
• Customer, shipping, tax, discount, and line-level attributes are mapped from Shopify to Manhattan order schemas, including split-ship and partial-cancel scenarios.
• Inventory availability is owned by Manhattan OMS; ATP and node-level quantities are synced to Shopify as sellable inventory or location stock, depending on store model.
• Fulfillment lifecycle updates from Manhattan (allocated, released, picked, shipped) are translated into Shopify fulfillments, including multi-package tracking numbers.
• Refund and cancellation decisions initiated in Manhattan are pushed back to Shopify with reason codes and line-level quantities to keep financial and operational states aligned.
• Delta-based sync sends only changed records; retries, dead-letter queues, and audit logs capture failures, payloads, and correlation IDs for traceability.
