Fast time to value

Use OneStock connectors and continuous platform evolution to ship faster. Use plug‑and‑play connectors and an API-first design to remove what, for other platforms, would be months of bespoke development, and accelerate go‑live across regions and channels.

API‑first platform

Modernize your architecture with OneStock’s API-first platform. Connect systems in real time with secure APIs and webhooks while retaining batch options for legacy systems.

Secure, scalable platform

Protect your architecture with a cloud-native, enterprise-grade platform. OneStock delivers secure, scalable infrastructure, industry-grade auth (OAuth2, SSO) and observability for high-volume commerce.

Monitor integrations in real-time

Monitor integration health and retrieve logs in real-time. Use OneStock’s observability features, webhook alerts and log exports to detect failures, replay events and act before business impact.

With OneStock, we were initially able to come and interconnect our tool to the OneStock application via the API, and we were also able to easily integrate the Widget. In fact, initially, we relied on the OneStock Widget and were able to integrate it very easily on our site to be able to make this transition.

Key Integration Capabilities

Everything you need to connect

Technical integration methods

OneStock supports three complementary integration methods: synchronous APIs for real‑time read/write, webhooks for event‑driven notifications, and SFTP for secure batch transfers. Use APIs for checkout-level stock and delivery promise checks, webhooks to push events to ERPs/marketplaces or log collectors, and SFTP for large catalog or inventory imports. The platform keeps core promise logic in‑platform to minimise third‑party calls and deliver typical response times in the order of a few hundred milliseconds for complex promise calculations.

  • Synchronous APIs — Real‑time bidirectional operations (order creation, check‑and‑reserve, delivery‑promise calculations). Ideal for checkout and PDP calls.
  • Webhooks — Outbound, event‑driven notifications (order_state_changed, stock_updated, shipment_created). Use to sync ERPs, marketplaces and monitoring systems.
  • SFTP / Batch — Secure file transfer for bulk imports/exports (catalogs, nightly stock snapshots, BI exports). Best for legacy ERPs or very large datasets.
  • Performance note — OneStock pre‑calculates and caches promise data to support high‑traffic calls; typical delivery‑promise responses are in the order of a few hundred milliseconds (see contract for SLA specifics).

Frequently asked questions

OMS integration connects your order management system to other software systems in your retail technology stack—including ecommerce platforms, ERPs, WMS, carriers, POS, and CRM—enabling quick and easy exchange of order, inventory, and tracking information in real-time. This eliminates data silos and ensures all systems operate on a single source of truth.

Implementation time varies based on system complexity, but OneStock’s pre-built connectors and API-first architecture dramatically reduce integration time. JD Sports deployed OneStock across multiple countries in just three months, while Pets at Home rolled out to 450 stores in one week after initial testing. Pre-built connectors for Shopify, Magento, and major carriers accelerate time to market significantly.

Yes. OneStock supports multiple integration methods including SFTP for file-based transfers commonly used with legacy ERP and WMS systems. OneStock Connect middleware handles custom data transformations for systems that cannot match standard API formats, supporting SOAP APIs, REST APIs, CSV files, and JSON formats. This ensures seamless integration regardless of system age or technical constraints.

OneStock provides pre-built connectors for major ecommerce platforms including Shopify, Magento, and commercetools and the API-first architecture enables integration with any ecommerce platform that supports REST APIs or webhooks, including custom-built solutions.
