A Shopify app touches live revenue and live customer data a broken webhook can mean unfulfilled orders, a bad GraphQL query can mean rate-limit bans, and a non-compliant billing implementation can get an app rejected or removed from the App Store entirely DM Today To Get Your Entire App Fixed

FAQ
My app was rejected by the Shopify App Store can you fix it?
Yes, send me the rejection reason from Shopify's review team and I'll audit against their current requirements (performance, security, billing compliance, UX guidelines) and fix the specific issues.
Do I need a private app or a public app?
If it's for your store only and won't be listed for other merchants to install, you need a private/custom app faster and cheaper to build. If you plan to sell it to multiple merchants via the App Store, you need a public app with OAuth, billing, and compliance built in from day one. Tell me your
My app worked before but broke after a Shopify update, what happened
Most likely an API version deprecation or a change in webhook/extension behavior. Shopify releases quarterly API versions and deprecates old ones if your app wasn't migrated, it can silently break. I'll diagnose the exact version conflict and migrate it.
What's the difference between REST and GraphQL for my project?
Shopify is phasing out REST in favor of GraphQL for most Admin API use cases, GraphQL is more efficient for complex queries and is where Shopify's roadmap is headed. I default to GraphQL unless there's a specific reason to use REST (e.g., a legacy integration requirement).
Can you connect Shopify to my existing backend/ERP/CRM?
Yes, via Admin API + webhooks for real-time sync, or scheduled batch jobs depending on your system's requirements. Let me know what system you're integrating and I'll confirm the best approach.

Do you handle Shopify Plus-specific features (Shopify Functions, Scripts)?
Yes, including the migration from legacy Shopify Scripts to Shopify Functions, which is now required for checkout customization on newer API versions.
