Quote: getOrigOrderId vs. getReservedOrderId

Question

Considering the class Magento\Quote\Model\Quote: What is the difference between the following two methods:
getOrigOrderId
getReservedOrderId

Thanks

Is it right that a quote would have a corresponding order only after placeOrder would be called for the current quote?
Do the methods mentioned above help to fetch the corresponding order for a quote?

Answer 1

The Magento\Quote\Model\Quote::getReservedOrderId() method is used when Order is placed and Quote is in the process of converting to a new Order. reserved_order_id then saved as new increment_id in sales_order table.

Also, PayPal Express module in Magento 2 uses reserved_order_id when before user is redirected to a PayPal page. It guarantees reservation of the order increment id once PayPal will redirect customer back to a website.

Neither getOrigOrderId nor setOrigOrderId used from Magento\Quote\Model\Quote class.
