By connecting Shopify with X (formerly Twitter) and taking advantage of X Shopping, you can display and sell the products registered on Shopify directly on your profile page on X. This guide clearly explains, based on the official features, the steps for syncing your product data to X through the Shopify app "X" and publishing and running a shop covering physical products only.
What Is X Shopping
X Shopping refers to the mechanism that lets merchants display and sell products directly on the X platform.
By using the Shopify app "X," you can sync your Shopify product data to X Shopping, allowing your Shopify products to be displayed on the X platform.
At present, X Shopping only supports "physical products." It does not support the sale of digital downloads, gift cards, ticket sales, subscriptions, reservations, NFTs, or other virtual products. (Source: X Shopping Policy)
