To integrate Shopify into a Strapi website, start by creating a new Strapi project using the `npx create-strapi-app` command, then run `npm run develop` to launch the admin dashboard. Create a new collection type named "Product" and add fields for product name, description, image, and shopifyID. Allow public users to view products by their ID and set up a private Shopify store account with API access. Install the `shopify-api-node` package to connect Strapi to Shopify's API. Modify the `findOne` controller function to retrieve product metadata using Shopify's API details. Create a product entry in Strapi that matches the product from Shopify, then publish it to see the integrated metadata.
