Redirect to cart from a different domain

[arunshan]

A client added us as a user and assigned a role in Magento backend. I would like to create a cart, add products and redirect to the cart URL from a different origin.

Scenario:
Say we have a simple cart implemented in experience.example.com and have products added to the cart. On checkout button click it should redirect to the client's website (say ippolita.com/checkout/cart) with the products in it. We would like to create a new session and a new cart every time a user clicks on the Checkout button in expereince.fuiszmedia.com.

Progress:

1. We can create a cart with a server side session
2. Adding products to the cart is done
3. But I am unable to redirect to the clients cart with products in it.

How would I get the link to the client's checkout page with cart and products in it?

The moveToCustomerQuote function in cart product adds the cart products to customer's cart. Is this the functionality you are trying to get?
