Adding Google OAuth to your Claude Code app? Let us review it.
Expert review for Google OAuth integrations built with Claude Code. We fix Claude Code-generated Google OAuth code for security, error handling & production readiness. From $19.
Common Claude Code issues affecting integrations
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Google OAuth issues we find in Claude Code apps
Missing CSRF state parameter validation
AI-generated OAuth flows don't generate or validate the state parameter, making the callback endpoint vulnerable to CSRF attacks that could link attacker accounts.
Using implicit grant flow instead of authorization code
Generated code uses response_type=token (implicit grant) which exposes tokens in the URL and is deprecated by Google in favor of authorization code with PKCE.
Refresh token not requested or stored securely
AI tools don't include access_type=offline in the authorization URL or store the refresh token securely, causing sessions to expire and requiring re-authentication.

Frequently asked questions
Can you review my Claude Code-built Google OAuth integration?
Yes. We regularly audit Google OAuth integrations in Claude Code-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Google OAuth issues does Claude Code typically create?
Common issues in Claude Code-generated Google OAuth code include: missing csrf state parameter validation, using implicit grant flow instead of authorization code, refresh token not requested or stored securely. We fix all of these in our code review.
How much does it cost to fix my Google OAuth integration?
Start with our code audit ($19) to get a complete list of Google OAuth issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What Google OAuth best practices does Claude Code typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for Google OAuth. Our review checks all of these and provides specific fixes.
