The key to successful automatic gift addition lies in the “Goal Reward” configuration. When setting up your gift goal, you’ll find this crucial setting under the reward configuration section. 

Here’s how to set it up:

1. Navigate to your gift goal settings
2. Under “Goal Reward,” select “Automatically add gifts to cart”
3. Choose your gift products
4. Set the gift quantity award
5. Configure maximum redemptions per order
6. Optionally set gift removable feature
   
   

This configuration ensures that as soon as a customer meets your qualification criteria, whether it’s a spending threshold, item count, or specific product purchase, their earned gifts will be automatically added to their cart without any additional action required.
