Another payment option that was available in the old admin was the ability to generate gift certificate codes (single or en masse) by going to the interface’s Settings ->Payment ->Gift Certificates section shown below.
As with the other payment options, this navigation has been shortened a bit. Now you will go to Settings ->Payment. Once there, look to the far right of the page and click on the “Gift Certificates” link under “More Options.”
The same functionality still exists where you can create one gift certificate code (for any amount) or group certificates to create as many as needed in one shot.
You can also access Group Certificates by going to Marketing ->Group Certificates in the New Admin
