Checkout

Your custom checkout domain

Your checkout runs on a subdomain of your own domain, which you point at us with one DNS record.

You set this up in the Go live stage or in Settings under Custom checkout domain. In Settings, it opens once your plan has started.

Add the record

  1. Choose a subdomain: checkout, shop or secure.
  2. Go to wherever your domain's DNS is managed.
  3. Add a CNAME record. Name or Host is your subdomain. Value or Target is the value shown on screen. TTL is Auto or 600.
  4. If the screen shows a TXT record too, add it once. It proves you own a domain registered elsewhere. Most providers add your domain to the name on their own. If yours asks for the full name, use _cf-custom-hostname followed by your full checkout address.
  5. Wait for the badge to turn green. It usually takes 5 to 30 minutes, and you can carry on with the rest of the setup while it spreads.

This does not affect your main store or the rest of your domain.

Where to add it

  • Domain bought through Shopify: Shopify admin, Settings, Domains, click your domain, Manage DNS settings, Add custom record, choose CNAME.
  • GoDaddy, Namecheap, Google and others: open the domain's DNS records page and add a new CNAME record.
  • Cloudflare: add the CNAME, then set it to DNS only (grey cloud, not the orange proxy).

What the badges mean

  • Pending DNS: we cannot see the record yet, or the security certificate is still being issued.
  • Waiting for approval: the domain is ready and waiting for Sling to approve it. There is nothing to do on your side. Your checkout moves to it once approved.
  • Active: the domain is ready.

Rules

  • A store can have up to 3 checkout domains. Remove one before adding another.
  • A checkout domain belongs to one store. If yours is claimed by another store and it is yours, contact support.
  • To remove an active domain, you type it exactly to confirm.
  • If you change your checkout domain, your old thank-you redirect no longer matches. Point it at the new address and confirm again. Until then your store is back in test mode.

Favicon

The same Settings section has a Checkout favicon field. It sets the little icon in the browser tab on your checkout.
