Adding Lemon Squeezy to your Codex CLI app? Let us review it.

Expert review for Lemon Squeezy integrations built with Codex CLI. We fix Codex CLI-generated Lemon Squeezy code for security, error handling & production readiness. From $19.

Common Codex CLI issues affecting integrations

security

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.

security

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.

code-quality

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.

Lemon Squeezy issues we find in Codex CLI apps

Webhook signature verification missing or incorrect

AI-generated handlers skip HMAC signature verification on incoming Lemon Squeezy webhooks, allowing anyone to forge subscription and order events.

Incorrect overlay checkout configuration

Generated code often misconfigures the Lemon.js overlay checkout, causing it to open in a new tab or fail to pass custom data back to your application.

License key validation not implemented server-side

AI tools frequently validate license keys on the client side only, making it trivial for users to bypass license checks entirely.
