Retail Express Hints
Order payment status
When using Retail Express with Magento and Codisto LINQ it is necessary to map the Codisto payment method to a payment method in the Retail Express Configuration (Magento Admin > System > POS System (v1.7) > Settings > Payment Methods. Add eBay Order to POS Payment > PayPal to have eBay orders show as paid with PayPal.
Stopping Combined orders duplicating orders in REX
Go to Marketplace Orders screen and change setting to "Only send orders when buyer has: Paid".
That means all pending / uncombined orders don’t get sent. Then buyer pays which settles final combining state so REX only sees final combined state.
