# Storefront API now supports cart attributes with blank keys or values

The GraphQL Storefront API now supports setting [cart attributes](https://shopify.dev/docs/api/storefront/latest/objects/Cart#field-attributes) with either blank keys or values. This change applies to all API versions. This matches the behavior of the [AJAX API](https://shopify.dev/docs/api/ajax/reference/cart#update-cart-attributes), which allows for setting blank keys and attributes.
