Using Shop API hooks, which feature can be automatically set during the checkout process?

The feature that can be automatically set during the checkout process using Shop API hooks is addresses. During checkout, it is crucial to capture and utilize the customer's shipping and billing information efficiently. The Shop API allows for automatic handling of address data, which ensures that customers have a smooth checkout experience without needing to re-enter their information if they have previously provided it. This capability optimizes the process by minimizing user input and reducing the chance of errors, making the checkout experience more seamless for the customer.

The other features, while important to the overall shopping experience, do not directly relate to automatic address handling during the checkout. User location might help in suggesting shipping options or locations but is not directly concerned with the address input itself. Customer reviews pertain to product feedback and are separate from the checkout process. Discounts, while critical for pricing strategies, usually need manual input from either the customer or the system rather than being automatically set through the Shop API hooks regarding address management.
