- From the Apps and sales channels page, click Shopify App Store.
- If applicable, then log in to continue to the Shopify App Store.
- From the Shopify App Store, search for Buy Button to learn more about the sales channel.
- Click Add channel or Add app.
After you've added the Buy Button sales channel, you can create a new Buy Button.
