## Delivery and Payment Customizations - Shopify Functions 

The Shopify Functions APIs for delivery and payment customizations are now generally available. These Functions APIs allow you to hide, reorder, or rename delivery and payment options directly in the checkout. 

One of the most popular delivery customizations include the ability to surface unique shipping options to specific buyers — like bike shipping options, that only display to customers that live within certain ZIP or postal codes. 

With regards to payment customizations, one of the most popular use cases is to hide certain payment options based on a dollar threshold.
