How to get Shipping address from order object in checkout api?

I am unable to get Shipping address from Response of CHECKOUT API. Sometime it include customer id but sometime there is no customer id why ?

:wave: With the Checkout API the response won’t include the shipping address. If you have ask_for_shipping_address set to true the Square Checkout collects shipping information on your behalf and stores that information with the transaction information in the Square Seller Dashboard.

If you have the customers shipping address you can include the pre_populate_shipping_address in the CreateCheckout request and the buyer’s shipping information is prepopulated on the checkout page as editable text fields.
