Sign In with World ID Common Pitfalls

Invalid Redirect URI

Ensure you've added your application's sign in callback URL to the list of allowed Redirect URIs in the Developer Portal.

Redirect URIs using http, localhost, or port numbers are only allowed for Staging applications.

Unauthenticated Errors

Ensure your Client ID and Client Secret are properly set in your environment variables according to your authentication library's documentation.

The Client Secret should never be exposed in client-side code. If accidentally committed to your codebase, you should rotate the client secret in the Developer Portal.
