# Stripe secret and restricted keys

The booking engine requests a Stripe secret or restricted key only for optional advanced card authorization (3-D Secure and pre-authorization).

If you created a restricted key and it is not being used, you can safely delete it in the Stripe dashboard under **Developers** and **API keys**.
