# URL Validation

To ensure your Users are always routed to the correct place, Stytch verifies any redirect URLs provided in requests against redirect URLs that are configured in the developer dashboard.

For each redirect URL type (`login`, `signup`, or `invite`), a developer can specify one or more URLs for each type.

Each Project also has separate redirect URLs for **test** and **live** environments. When verifying the redirect URL from the request against the predefined URLs for the project, Stytch looks for an exact match, including any subdirectories and query parameters. Please visit the [Dashboard](https://stytch.com/dashboard/redirect-urls) to set redirect URLs for your project.

By default, all redirect URLs are set to [http://localhost:3000](http://localhost:3000) for Test environments.
