Subdomains let you use your own domain (e.g. link.yourdomain.com) for Linkrunner tracking links and deep links instead of a generic URL. This makes your links more branded and trustworthy to users. What you need:
  • A domain you own
  • Access to your domain’s DNS settings

​
Step 1 — Choose a subdomain

From the Linkrunner dashboard, go to Settings > Subdomains and click Add Subdomain. Enter a subdomain prefix (e.g. link, app, get, open) and your domain name. Your subdomain will look like: subdomain.yourdomain.com

​
Step 2 — Add a CNAME record

Go to your domain registrar’s DNS settings and add a CNAME record with these values:
NameTypeValue
your-subdomainCNAMEapi.linkrunner.io
For example, if your subdomain is link.example.com, set:
  • Name: link
  • Type: CNAME
  • Value: api.linkrunner.io

​
Provider-specific guides

  1. Log in to your GoDaddy account and go to My Products
  2. Find your domain and click DNS (or Manage DNS)
  3. Click Add New Record
  4. Select CNAME as the record type
  5. In the Name field, enter your subdomain prefix (e.g. link)
  6. In the Value field, enter api.linkrunner.io
  7. Leave TTL as the default (or set to 1 hour)
  8. Click Save

​
Step 3 — Verification

After adding the CNAME record, Linkrunner automatically checks your DNS configuration and provisions an SSL certificate.
  • CNAME Not Verified — DNS record hasn’t been detected yet. This can take a few minutes to propagate.
  • CNAME Verified — Your DNS record is correctly pointing to api.linkrunner.io.
  • SSL Active — Your SSL certificate has been provisioned. Your subdomain is fully ready to use.
You can click the refresh button next to your subdomain in the dashboard to manually re-check the status.

​
Troubleshooting

DNS propagation delay DNS changes can take up to 24–48 hours to propagate globally, though most providers update within a few minutes. If your CNAME isn’t verified after adding it, wait and try refreshing later. Wrong CNAME value Make sure the CNAME value is exactly api.linkrunner.io — not your subdomain URL, not an IP address. Cloudflare proxy interference If you use Cloudflare, ensure the proxy status is set to DNS only (grey cloud). The orange cloud (proxied) mode will interfere with SSL certificate provisioning. SSL still pending SSL provisioning happens automatically after CNAME verification and usually takes a few minutes. If it remains inactive after 30 minutes with a verified CNAME, contact support.

Managing subdomains

From the Settings > Subdomains page in the dashboard, you can:
  • Add new subdomains to your project
  • Delete subdomains you no longer need
  • Monitor the CNAME and SSL status of each subdomain
