Custom Domains for Link-in-Bio Tools

Why custom domains matter for link-in-bio tools

links.acme.com is more memorable than yourapp.bio/acme and tracks cleaner in analytics. Creators with audiences over 10K consistently want their own domain, and they'll switch platforms to get it. Now you don't have to be the platform they switch from.

What your users get

• Link-in-bio page at the creator's domain
• Bio link analytics attributed properly
• Apex domain support, not just a subdomain

How it works in 3 steps

1. Your user types their hostname (links.acme.com) into your UI.
2. your link-in-bio tool 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": "links.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.
