# Checkout URL query parameters no longer contain customer details

In limited circumstances, such as when using [cart permalinks](https://shopify.dev/apps/channels/cart-permalinks), customer details like email and shipping address could be contained in the query parameters of the resulting checkout URL.

These customer details no longer appear in checkout URLs. Features that resulted in this behavior like [cart permalinks](https://shopify.dev/apps/channels/cart-permalinks) should continue to function as normal.
