About this gig

MY SERVICES INCLUDE:

- Shopify Functions
- Billing and subscription setup

I use current Shopify architecture and avoid legacy REST for new public distributions. Checkout features may require Shopify Plus depending on the extension target. Hosting, paid APIs, external services, and App Store approval are separate.

FAQ
What can you build with a shopify custom app?
A shopify custom app can automate store tasks, connect external systems, add admin tools, or extend storefront and checkout workflows. Shopify app development scope depends on the required APIs, data, and merchant experience.
Can you build a public Shopify app for the App Store?
Yes. I can handle shopify app development for a shopify public app or shopify custom app with authentication, billing, event subscriptions, testing, and App Store submission preparation. Shopify approval is not guaranteed.
Can you integrate third-party APIs with Shopify?
Can you integrate third-party APIs with Shopify? Yes. I can build shopify API integration for ERPs, CRMs, fulfillment tools, SaaS products, or custom backends using the GraphQL Admin API, secure authentication, webhooks, and mapped data flows
Do you work with Shopify Functions and checkout features?
Yes. Shopify Functions can support eligible discount, delivery, payment, and validation logic. A checkout UI extension can add supported interface elements, while some checkout targets require Shopify Plus
Can you improve or fix an existing shopify custom app?
Yes. I can audit a shopify custom app, fix API or webhook issues, update extension code, improve data handling, and modernize shopify app development where the existing codebase and access allow it.
What do you need before starting shopify app development?
Send your app goal, target stores, required features, API documentation, existing code if any, access needs, extension requirements, hosting preference, and deadline. For a shopify custom app, also explain the exact merchant workflow.
