Adding Shopify API to your Codex CLI app? Let us review it.
Expert review for Shopify API integrations built with Codex CLI. We fix Codex CLI-generated Shopify API code for security, error handling & production readiness. From $19.
Common Codex CLI issues affecting integrations
API keys and secrets written directly into generated source files
Codex CLI generates code with placeholder credentials that developers often replace with real values inline, leaving secrets committed to version control. There is no .env scaffolding or secret management setup by default.
No authentication or authorization on generated API endpoints
When Codex generates Express or FastAPI backends, routes are created without middleware for authentication, meaning every endpoint is publicly accessible immediately after deployment.
Single-file output breaks apart for any real project structure
Codex frequently outputs all logic into one or two files rather than organizing code into modules, services, and utilities — making the result hard to maintain and extend as the codebase grows.
Shopify API issues we find in Codex CLI 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.
