Shopify does not let external apps edit your theme automatically, so this page generates the exact code you paste once into your theme. After that, every cart checkout click goes to your custom checkout instead of Shopify's checkout.

Your public checkout address

Must be your live address (or your own domain) — never the private editor preview address, which asks visitors to log in.

1
Open your Shopify admin
Go to Online Store → Themes, click Customize on your active theme, then click Edit code.
2
Create the snippet
In the Snippets folder, click Add a new snippet. Name it custom-checkout-redirect.liquid, then paste the code above and save.
3
Include it in your theme
Open layout/theme.liquid and add this line just before the closing </body> tag:{% render 'custom-checkout-redirect' %}This covers the cart page, the cart drawer and product pages in one place.
4
Test the redirect
Click checkout in the cart, and also click "Buy it now" on a product page. Both should land on https://sawcollect.store/checkout?items=....

Why not fully automatic? Shopify does not expose an API that lets external apps replace the checkout button in your theme. Apps like Checkify still require a one-time theme edit. This snippet does the same thing in a single copy-paste step.
