Manually create a gift card
If you have PW Gift Cards Pro you can manually create a gift card from the admin area by going to Pimwick Plugins > PW Gift Cards > Create Gift Card.
Without the Pro version the easiest way to send a gift card to a customer is to first create a WooCommerce Coupon that only you will use. Set the coupon to be 100% off the cart.
Then simply order a gift card through the front end and specify the To email address for the recipient. Apply your coupon code during checkout so that you don’t have to actually pay anything.
