Custom domains and CNAME setup
Reviewed · QR Codes Unlimited
To show your own domain when a QR code is scanned, connect a subdomain such as qr.example.com. Add a CNAME record at your DNS provider with Name qr and Target custom.o2o.to, then save the full subdomain in QR Codes Unlimited. Use an unused subdomain and leave your website and email records unchanged.
A custom domain changes the encoded scan link, not the final destination. Download and print the new QR image after connecting it. Existing printed images keep their original link, so keep their old domain working.
Standalone dashboard
Open Links > Domains to add and check your subdomain. Custom domains require the applicable paid plan or trial access.
Shopify app
Open Apps > QR Codes Unlimited > Settings > Links & tracking. Custom domains are included with Startup and Growth. Use the guide for the provider managing your DNS; a myshopify.com address is not an editable custom domain.
