Customers can use the dynamic checkout button to quickly buy the product they're viewing. They skip the cart and complete their payment with the checkout method displayed on the button. The button dynamically changes to reflect the customer's preferred accelerated checkout method.
The button is displayed next to the Add to cart button and can be used to buy only single variants of a product. For example, a customer can use a dynamic checkout button to buy two red t-shirts, but not a red t-shirt and a blue t-shirt.
The checkout method that's displayed on the button depends on a few factors:
your payment settings
the customer's browser
the customer's device
the customer's personal payment history
There are two different kinds of dynamic checkout buttons:
Unbranded - These buttons display Buy it now text. When a customer clicks an unbranded button, they skip the cart and go to the Shopify checkout.
Branded - These buttons show the logo for a third-party accelerated checkout method. When a customer clicks a branded button, they complete their payment with that accelerated checkout method. The following third-party accelerated checkout methods are available:
Only the payment methods that you've enabled in your payment settings appear as options to your customers. If you don't have a third-party accelerated checkout method enabled, then only the unbranded button is displayed.
