What a Shopify App Developer Builds

Private Admin Apps

Build internal tools that extend the Shopify admin: custom order management workflows, bulk editing tools, internal reporting dashboards, and fulfillment automation.

Theme App Extensions

Build app blocks and app embeds that inject functionality into merchant themes without modifying theme code — the correct way to add persistent features across theme updates.

Shopify Functions

Build custom checkout logic: custom discounts, payment method customization, cart validation, and delivery customization using Shopify Functions.

Webhook Integrations

Build reliable webhook receivers for order creation, fulfillment updates, and inventory changes with idempotency handling and retry logic.

Custom Storefront Integrations

Connect Shopify to internal tools (ERP, WMS, CRM) via custom API integrations when no off-the-shelf app exists for your specific system.

App Migration

Migrate from deprecated private app API keys to the modern custom app authentication model, updating webhook subscriptions and API version calls.

Frequently Asked Questions

What is the difference between a private app and a custom app on Shopify?

Shopify deprecated private apps in 2022. Custom apps are the current equivalent — installed to a single store, not listed in the App Store, using OAuth 2.0 authentication.

When do I need a custom app vs an existing app from the App Store?

You need a custom app when no existing app solves your exact problem, when data must stay internal, or when you need direct integration with a proprietary system.

How long does a custom Shopify app take to build?

Simple integrations: 1–2 weeks. Custom admin tools: 2–4 weeks. Complex apps with multiple integrations and Shopify Functions: 4–12 weeks depending on scope.

What are Shopify API rate limits and how do they affect custom apps?

REST API: 2 requests/second. GraphQL: 50 points/second. Custom apps must implement retry logic and queue management for bulk operations to avoid hitting these limits.

Can a custom Shopify app be submitted to the Shopify App Store?

Yes — requires a Shopify Partner account, passing the App Store review process (2–4 weeks), and committing to ongoing maintenance. A custom app can be converted to a public listing.
