Adding Google OAuth to your Supermaven app? Let us review it.
Expert review for Google OAuth integrations built with Supermaven. We fix Supermaven-generated Google OAuth code for security, error handling & production readiness. From $19.
Common Supermaven issues affecting integrations
Fast completions accepted without review introduce subtle type errors
Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.
Security-sensitive code patterns completed without security review
In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.
Existing codebase anti-patterns replicated across new files at high velocity
Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.
Google OAuth issues we find in Supermaven 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 Supermaven-built Google OAuth integration?
Yes. We regularly audit Google OAuth integrations in Supermaven-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Google OAuth issues does Supermaven typically create?
Common issues in Supermaven-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 Supermaven 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.
