How can I integrate WMS inventory APIs with order creation?

Shopify Discussion

Topic summary

Integrating a Warehouse Management System (WMS) with Shopify for order creation using external inventory APIs.

  • Key question: Whether Shopify supports runtime inventory checks (and reservations) via a WMS’s APIs prior to creating an order, instead of syncing stock into Shopify’s native inventory.

  • Context: The WMS exposes APIs for inventory-check, inventory-reserve, and order creation; the app aims to call these before placing the order.

  • Terms:

    • WMS: Warehouse Management System that manages stock and fulfillment.
    • Runtime inventory check: Querying real-time stock availability on demand.
    • Shopify inventory module: Shopify’s built-in stock tracking.

  • Status: No responses or guidance provided yet; the question remains open with no decisions or action items.

How can i access the inventory check apis from my WMS before creating an order?

I am trying to create an app to integrate Shopify with my WMS which exposes APIs to perform inventory-check, inventory-reserve and order creation. Does shopify support a runtime inventory check instead of me having to sync the inventory to shopify inventory module?
