Custom Domains for Help Centers

Why custom domains matter for help center and knowledge-base platforms

help.acme.com is the URL customers paste into support tickets. It's also the URL Google indexes for their product's help content. Without it, you're losing branded search traffic and confusing customers who get bounced to a third-party domain.

What your users get

• Help center lives at the customer's own domain
• SEO credit goes to the customer's site
• TLS handled, including renewals

How it works in 3 steps

1. Your user types their hostname (help.acme.com) into your UI.
2. your help center platform POSTs to the Domainee API to register it and gets back the CNAME the user needs to add at their DNS provider.
3. We monitor DNS, issue the cert via Let's Encrypt, and webhook back when it's live. Usually about 60 seconds.

The code

curl -X POST https://api.domainee.dev/v1/domains \
  -H "Authorization: Bearer $DOMAINEE_API_KEY" \
  -H "content-type: application/json" \
  -d '{
    "hostname": "help.acme.com",
    "originUrl": "https://app.your-saas.com",
    "mode": "proxy",
    "redirectWww": true,
    "metadata": { "workspaceId": "your-internal-id" }
  }'

The response includes a dnsRecords array (usually one CNAME). Show that to your user, tell them to paste it at their DNS provider, and we'll handle the rest.

Used by Vidocu: when their AI generates a help article from a product video, the company's help center serves it at help.acme.com via Domainee.
