Create Cart Redirect URL

Creates a **Cart** redirect URL for redirecting a shopper to an already created cart using the `cartId`. **Usage Notes** * Redirect URLs can also be created with **Create a Cart** requests by appending `include=redirect_urls`. * A **Carts** redirect URL may only be used once. * Redirect URLs point to either a shared checkout domain or a channel-specific domain, depending on the storefront configuration. * Once a redirect URL has been visited, it will be invalidated and cannot be used again....
