We aren’t familiar with the Export Orders Plugin however the line item type for purchased gift cards is “pw_gift_card”.
If you are using the WooCommerce REST API there is a field in the Orders API endpoint for redeemed gift cards (pw_gift_cards_redeemed) that is an array that contains two fields:
"pw_gift_cards_redeemed": [
{
"number": "25JB-HZ6R-D8U3-PBUL",
"amount": "10.000000"
}
],
If no gift cards were used on the order it will be an empty array:
"pw_gift_cards_redeemed": [],
When a gift card is purchased there is a new Order Line Item type (pw_gift_card) that contains the gift card number, amount, etc inside the Order Line Item Meta.
Hope this information helped, I’m marking the thread as resolved. Best of luck with your project!
