Configuration with Shopify
If you purchased your domain name through Shopify, you should set up your domain name directly in the Shopify client area. If you did not purchase your domain name from Shopify, you will need to go to your hosting company's customer area.
Go to the Domains menu and click on your domain.
Click on Add a subdomain and enter the 3 letters that our system has randomly generated and confirm.
The system will automatically create the subdomain and a new CNAME entry
In DNS settings, edit the new CNAME entry that corresponds to the subdomain created earlier.
Enter the following value in the 'Target or Point to' field: custom.metaffiliation.com. (the dot at the end must be kept) and validate.
The settings are complete, please take into account the propagation time of maximum 24 hours.
