Instead of "https://yoursubdomain.firstpromoter.com" you can use your own domain and subdomain like "http://affiliate.yourdomain.com" or "https://partners.yourdomain.com" or something else.
Note: This feature is available only for Business plans or higher.
To achieve this please follow these steps:
Step 1)
Go to your DNS provider and create a CNAME record pointing to "proxy.firstpromoter.com" .
Note: If you want to use Cloudflare proxy (with the orange cloud activated) please contact us first, do not point it yourself as this will create SSL certificates conflicts and the website will stop working.
Step 2)
Open the Settings page (top - right button) and enter the subdomain you just set the CNAME for on "Your website sub-domain for the affiliate/referral program" field. Save the settings.
Step 3)
Wait a few minutes than do a test to the new address (the first request may take up to 30 seconds)
