Setting up one click checkout buttons on Cart
How to show accelerated/express checkout buttons?
To get more information on Shopify's definition of accelerated checkout buttons, you can read their guide at this link.
Accelerated or express checkouts save customer payment and shipping information so that returning customers can more quickly complete payment for their orders. By using dynamic checkout buttons, customers can skip Shopify's standard cart and go directly to the checkout from the product page using the selected accelerated checkout method.
Keep in mind that Upsells Cart can only display the accelerated/express checkout buttons set up on the Shopify default "cart page" from your theme.
To show these buttons on the app follow these steps:
- In your Shopify Admin go to Online Store->Themes-> Click the three dots button next to Customize and select Edit code in the dropdown menu.
