This feature is designed to load the customers cart over to the web version of your store. It allows both guest and registered customers to load their carts to continue shopping or checkout what they have in the cart added via your headless application without exposing login details. It’s handy if you have not yet worked with payment gateway like Stripe to handle the headless checkout.
