From the Shopify Help Center: “You can use the Buy Button sales channel to create Buy Buttons. Buy Buttons link to your Shopify checkout, so you can sell products on websites and blog posts, or create a checkout link to send to customers in email messages or on social media. No matter where you sell, you can track Buy Button orders from your Shopify admin.”
There are a couple of ways to use the buy button. You can use the code to just generate a button (which can be styled to your specifications) or you can output the product images and descriptions you have loaded in Shopify.
In the case of Prenupta, I imagine that we will manage images and descriptions on the WordPress end, and just output the button, but for the sake of this example, I am using the embed code that outputs the images, description & button.
