Shopify app development for real merchant workflows

A custom Shopify app should solve a specific operational problem. We define the data, permissions, events and failure cases first so the architecture follows the business requirement.

Custom & public Shopify appsBuild focused applications for individual merchant requirements or products intended for distribution to multiple Shopify stores.
Shopify Admin APIWork with Shopify APIs for products, inventory, orders, customers and other permitted store operations.
OAuth & installation flowsImplement secure app installation, authentication and permission handling appropriate to the app’s distribution model.
Webhooks & synchronizationRespond to Shopify events and build reliable background synchronization, notifications and operational workflows.
External system integrationsConnect Shopify with external APIs and business systems using validated, observable data flows.
App maintenance & troubleshootingInvestigate authentication, API-version, webhook, deployment, billing and data-flow problems in existing Shopify apps.

Experience building a public Shopify app

Xpert Developerz develops Xpert Store AI, a public Shopify app for AI-assisted store operations. That work gives us practical experience with installation, APIs, webhooks, compliance and ongoing app maintenance.

Custom app or public Shopify app?

A custom app can solve requirements for a particular merchant, while a public app is designed for multiple merchants and introduces additional product, installation, billing, compliance and App Store considerations.
