OAuth Setup Failing on Replit
OAuth providers reject your Replit application with invalid redirect URI or misconfigured credentials. Your login flow fails when redirecting back from the OAuth provider.
This commonly happens when the redirect URI registered with the OAuth provider doesn't match your Replit deployment domain or when environment variables are missing.
Error Messages You Might See
error_description: invalid_redirect_uri
Invalid redirect_uri parameter
The redirect_uri MUST match the registered redirect_uri
Common Causes
- Redirect URI mismatch between OAuth provider config and Replit domain
- Missing or incorrect environment variables (CLIENT_ID, CLIENT_SECRET)
- Using localhost instead of Replit production domain in OAuth settings
- OAuth provider not whitelisting Replit's deployment domains
- Replit URL includes .replit.dev but provider expects just domain
How to Fix It
Verify your OAuth provider settings match your Replit deployment URL exactly (e.g., https://myapp-username.replit.dev). Check that CLIENT_ID and CLIENT_SECRET are set in Replit Secrets. Some providers require explicit https:// and trailing slash consistency.
