Adding Google OAuth to your Replit Agent app? Let us review it.
Expert review for Google OAuth integrations built with Replit Agent. We fix Replit Agent-generated Google OAuth code for security, error handling & production readiness. From $19.
Common Replit Agent issues affecting integrations
Secrets stored in Replit environment
API keys and credentials stored in Replit's secrets manager don't transfer when you export the project. Developers often hardcode them as a workaround, creating security risks.
No HTTPS or security headers
Replit's development environment doesn't enforce HTTPS or set security headers. Apps deployed without proper configuration are vulnerable to man-in-the-middle attacks.
Database connection instability
Replit's hosted databases can disconnect unexpectedly. Without connection pooling and retry logic, apps crash or lose data during these interruptions.
Google OAuth issues we find in Replit Agent 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 Replit Agent-built Google OAuth integration?
Yes. We regularly audit Google OAuth integrations in Replit Agent-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What Google OAuth issues does Replit Agent typically create?
Common issues in Replit Agent-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 Replit Agent 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.
