Generate Cart and Checkout URL for Quote
Generates a cart URL and a checkout URL for a specific quote based on the provided `quote_id`.
You can only generate cart and checkout URLs for quotes in one of the following [statuses](#quote-statuses):
* New (0)
* In Process (2)
* Updated by Customer (3)
This endpoint will generate a checkout link for a quote even if it is configured to hide the checkout button on the Buyer Portal. You can use this to create an alternate checkout flow for your sales quotes.
