The Shopify Buy Button Channel does one thing well: it gives you a JavaScript snippet you can paste on any external site to let visitors add a product to a Shopify cart. It’s free, it’s first-party, and for plenty of stores it’s exactly enough.
It stops being enough the moment you need any of the following:
- A different cart, discount, or customer pre-fill per recipient (per email, per influencer, per ad creative)
- A link with an expiry, usage limit, or passcode
- Click and checkout analytics by source, campaign, or UTM
- A QR code that goes straight to checkout, not to a product page
- The customer to never see a “type your discount code” field at checkout
That’s where Checkout Links comes in. This page is the honest comparison.
How it works on Shopify
- Install Checkout Links from the Shopify App Store. 7-day free trial, no credit card.
- Create a link — pick products, optionally set a discount, optionally pre-fill customer or notes, optionally set expiry or limits.
- Drop the link anywhere — email, SMS, ad, QR code, Discord, in-store sign. Same link works in all channels.
- Track results — every click, every checkout, every dollar attributed back to the specific link.
It’s built for Shopify, runs on Shopify checkout, uses Shopify Functions for the discount layer, and integrates natively with Shopify Flow.
