Adding Shopify API to your GPT Engineer app? Let us review it.
Expert review for Shopify API integrations built with GPT Engineer. We fix GPT Engineer-generated Shopify API code for security, error handling & production readiness. From $19.
Common GPT Engineer issues affecting integrations
No authentication system
GPT Engineer generates functional UIs but typically skips authentication entirely. All routes and data are publicly accessible.
Direct database access from client
Some generated apps query databases directly from the frontend without an API layer, exposing database credentials and structure.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Shopify API issues we find in GPT Engineer apps
Using deprecated REST Admin API instead of GraphQL
AI tools generate REST API calls that hit aggressive rate limits and miss features only available through the Shopify GraphQL Admin API.
Missing HMAC validation on OAuth callbacks and webhooks
Generated code skips the HMAC signature verification on both the OAuth callback URL and incoming webhooks, creating serious security vulnerabilities.
Incorrect session token handling for embedded apps
AI tools use cookie-based auth for embedded Shopify apps instead of session tokens from App Bridge, which fails due to third-party cookie restrictions.
