About This Service

Shopify Custom Feature & Private App Development (Admin API, Functions, Webhooks)

When a Shopify app from the App Store doesn't quite fit, I build the custom feature or private (custom) app that does — purpose-built for your UAE business logic. I develop against the Shopify Admin GraphQL API, Storefront API and Shopify Functions, using webhooks, metafields, and the App Bridge embedded-app framework. Common builds: custom discount and bundle logic with Shopify Functions, ERP/POS sync, automated order routing, custom checkout UI extensions, subscription flows, and dashboards that pull live store data.

For UAE merchants I frequently build integrations with local systems — Zoho Books and Xero for VAT-compliant accounting, Aramex and Fetchr for automated label generation and tracking, WhatsApp Business API for order notifications, and Tabby/Tamara reconciliation. Apps are built in Node.js or Remix on the Shopify CLI, deployed reliably, and secured with proper OAuth scopes, webhook HMAC verification and rate-limit handling so they survive real traffic.

You get production-ready code, documentation, and a feature that automates the manual work currently eating your team's time — whether that's syncing inventory, applying complex GCC pricing rules, or routing orders to the right Emirate warehouse.

What's included

  • Custom app on Shopify CLI — Embedded app via App Bridge, built in Node.js or Remix against the Admin GraphQL API.
  • Shopify Functions — Custom discounts, bundles, delivery and payment customizations that run natively at checkout.
  • Secure by default — OAuth scopes, webhook HMAC verification, rate-limit handling and least-privilege access.
  • Local integrations — Zoho/Xero VAT accounting, Aramex/Fetchr labels, WhatsApp Business API notifications.
  • Automation — Order routing, inventory/ERP sync, and dashboards that remove manual data entry.
  • Docs & handover — Documented code, deployment notes and a walkthrough so your team can maintain it.

How it works

  1. 1
    Scope the logic

    We define the exact behaviour, data sources and edge cases — what triggers it and what it must output.

  2. 2
    Build & integrate

    I develop the app/Function against the Admin GraphQL API and wire up webhooks and external systems.

  3. 3
    Test on a dev store

    I validate on a Shopify development store with real scenarios before anything touches production.

  4. 4
    Deploy & document

    I deploy, install on your store, and hand over documentation plus a maintenance guide.
