The Shopify WordPress integration works by adding a Shopify Buy Button to your WordPress site. This way, you maintain every aspect of your website (blog, site design, SEO) on WordPress, but you can also sell products and process payments with a simple button from Shopify.
Here’s how it works:
Create a product in Shopify (images, product description, and price).
Copy the embed code for the Shopify product.
Paste that code anywhere on WordPress to embed Shopify products on the site.
Then, customers go to your WordPress site to see the Shopify products. But to purchase, they’re sent through a Shopify checkout module.
