Custom domain guides

Use a custom domain for your QR codes

Let people see a link like qr.example.com when they scan your QR code. Your code still opens the website, file, or other destination you choose.

Where are your DNS records managed?

Choose the service that manages your domain's DNS. It may be different from the company where you bought the domain. For example, a domain purchased at GoDaddy can use Cloudflare DNS.

GoDaddy

For domains whose DNS records are managed at GoDaddy.

The record you need

For a domain you own, such as example.com, create the record below. It gives your QR codes the subdomain qr.example.com.

Type: CNAME
Name / Host: qr
Target / Value: custom.o2o.to
TTL: Default

Use an unused name such as qr. Keep the existing records for your website and email. On Cloudflare, set this new QR record to DNS only.

A CNAME tells DNS to send requests for your subdomain to our QR service. It does not choose the final destination of your QR code; you do that in the QR editor.

Connect the subdomain in your QR code account

DNS setup is only the first step. Add the same full subdomain, such as qr.example.com, in the product you use. Custom domains require a plan that includes this feature.

QR Codes Unlimited

Open Links → Domains. Enter the full subdomain without https:// or a path. Let the domain check run, then select Save Changes. If the page asks you to upgrade, choose a plan with custom domains first.

QR Code Hub for Shopify

Open Apps → QR Code Hub → Settings → Redirect Page in Shopify admin. Choose QR Code Hub as the redirect option, enter your subdomain in the custom-domain field, and use Shopify's save bar to save. The field is available on plans that include custom domains.

The CNAME setup is for the app's direct redirect option. If you use the storefront homepage or an app-generated Shopify page as the redirect page, that flow uses your storefront domain.

Using another provider?

Look for DNS records or DNS management in your provider's control panel. Add a CNAME using the name and target above, keep the default TTL, and enter the full subdomain in your QR code account. Use the provider's documentation if its field names differ.

If you do not know who manages your DNS, check the nameservers shown in your domain account or ask the person who manages your website.
