Get Current Cart

Notes:

• A 'current cart' is automatically created when the site visitor/member adds an item to their cart, or when calling Add To Current Cart.
• Calling this method before adding an item to the cart returns a 404 error.
• This method doesn't calculate or return price totals. To get estimated totals including tax, shipping, and discounts, use Estimate Current Cart Totals.
• This method requires visitor or member authentication.
