Ecommerce API Services

A Node.js and Express service layer sitting between more than one storefront and the systems behind them — Shopify APIs, Google APIs and the shared operations each store would otherwise reimplement.

ConfidentialPrivate Client ImplementationAPI
Overview

When two storefronts need the same thing done, the choice is to build it twice or to build it once behind an API. This is the second option: one Express service holding the shared commerce operations, reached by more than one storefront, with the configuration that differs between them passed in rather than forked. Credentials are held in managed secret storage rather than in environment tabs, and each consumer authenticates as itself instead of sharing one key. The client is confidential; the architecture is not.

Client identity and implementation details are confidential. Endpoints, project identifiers and service accounts are deliberately not described.

What EcomLabs did

  • Designed and built a shared commerce service layer in Node.js and Express.
  • Integrated Shopify APIs and Google APIs behind a single internal contract.
  • Separated per-store configuration from the service so one codebase serves several storefronts.
  • Moved credentials into managed secret storage and scoped access per consumer.

Capabilities

  • REST endpoints shared by more than one storefront.
  • Shopify Admin and Storefront API integration behind one contract.
  • Google API integrations for the operations that need them.
  • Per-store configuration as input rather than a forked codebase.
  • Managed secret storage and per-consumer authentication.
