OneStock Connector for Shopify
Introduction
About the connector
OneStock provides a connector that integrates your Shopify store with the OneStock Order Management System (OMS), so that Shopify can rely on OneStock for advanced order orchestration and inventory management.
The connector is continuously maintained and developed by OneStock engineers with expertise in Shopify development.
What does the connector do?
We synchronize essential data between Shopify and the OneStock OMS to ensure smooth and reliable operations.
Through Shopify, we display OneStock delivery methods that take into account multiple parameters such as carriers, your products, order value, and many other criteria.
With the OneStock connector, you can leverage app proxy to enrich your e-commerce website experience.
Benefits for you and your customers
Integrating your Shopify site with OneStock allows you to create a smooth flow of information between the two systems.
Reduces integration time and effort by providing pre‑built, tested flows for products, inventory, and orders, instead of custom API integrations.
Acts as a secure proxy between Shopify and OneStock, allowing you to rely on OneStock-managed authentication and connectivity.
Maintained, enhanced, and supported by an internal, dedicated team of experts in Shopify development. It remains compatible with the latest Shopify versions and consistently updated with new OneStock features. The OneStock connector is developed with a focus on minimizing backward compatibility issues, making updates smoother and easier.
Your customers browsing your website can thus:
Take advantage of the delivery promise through a Shopify extension.
Benefit from OneStock’s orchestration rules (ship‑from‑store, split orders, multi‑location sourcing) applied automatically to Shopify orders.
In the following sections, we detail the data flows between Shopify and OneStock (products, inventory, orders, statuses), how delivery promises are displayed in the Shopify checkout, and which checkout scenarios (shipping, Click & Collect, pickup points, etc.) are supported or limited
Why we built this connector?
It is designed for Shopify merchants who want to extend their existing capabilities and embrace omnichannel commerce, by enabling in-store inventory visibility, ship-from-store and in-store returns through the OneStock store application.
Without the connector, each Shopify X OneStock integration would require a custom, project-specific development and maintenance effort.
The OneStock connector standardizes:
Authentication and secure communication between Shopify and OneStock.
Core data flows (products, inventory, orders, statuses).
Display of OneStock delivery promises in the Shopify checkout
This reduces project risk, accelerates time-to-market, and ensures long-term compatibility with Shopify and OneStock updates.
