Free products can only be redeemed on Shopify, and must use Shopify Functions. If you are still using Shopify Scripts for free products, get in touch and we’ll switch you over to Shopify Functions

Use this endpoint to redeem a free product reward, which can then be added to the customer’s cart and checked out along with their other items.

Redeeming free products requires the use of the Storefront API to add the free product to the customer’s cart, at which point a LoyaltyLion Shopify Function will apply the discount.

If you’re using Shopify Hydrogen, see our implementation guide for free product rewards.

​
Choosing a variant

The reward may have been configured with multiple eligible product variants. If this is the case, you’ll need to let the customer choose which variant they want to redeem, and then pass that ID as variant_id when performing the redemption.
