With Tolt, your affiliate portal can have a custom domain, i.e. affiliates.domain.com instead of a subdomain.

The setup for this is pretty straightforward. Although you need to have access to your DNS provider(i.e. Cloudflare) or register(Namecheap, Godaddy etc...).

You need to create a CNAME record of your desired domain that will point to domains.tolt.io.

First, add your domain in Program Settings -> Affiliate Portal:

Then inside your registrar create a CNAME record with the domain you add inside Tolt.

For this tutorial, I'll be using Cloudflare:

Afterward, go back to Tolt and click Verify.

Note that the domain might take a few hours to be verified!

If the status says VERIFIED, then your affiliates can access your portal with the new domain!
