Hyperspace enables you to use Lightspeed gift cards in your Shopify checkout page. You must be using Shopify Plus to enable this feature. Shopify Plus is the only version of Shopify that allows you to edit the source on the checkout page.
To start you need to contact Shopify support and enable the Gift Card Adjustments API.
Once enabled, this extension will appear in your Shopify Admin under Apps > Private Apps.
It is not active by default. Only Shopify support can enable this feature for Lightspeed gift cards.
Once this is active, contact Hyperspace to implement your gift card integration for Lightspeed.
