Links & destinations
Custom domains
Serve branded short links from your own hostname. CNAME to custom.letl.ink; TLS is issued for you.
A custom domain makes short links look like you: https://go.example.com/summer instead of https://letl.ink/summer. Free workspaces cannot add domains. Solo allows 1, Growth 3, Ultimate 50.
DNS
- In your DNS host, create a CNAME for the hostname you want (for example
goonexample.com). - Point it at
custom.letl.ink. - Wait until the CNAME resolves. TTL of 300–600 seconds is plenty while you are testing.
- In Letlink, open Integrations → Custom Domain, enter
go.example.com, and add it. Only workspace owners and admins can do this. - Wait for verification. TLS certificates are issued and renewed automatically once the hostname is under our SSL service.
| Type | Name | Value |
|---|---|---|
| CNAME | go | custom.letl.ink |
Using it on a link
When you create or edit a link, pick the verified hostname from the domain control. The short URL copies as https://go.example.com/your-code. API creates accept the same hostname in the domain field; GET /api/v1/links requires a domain query parameter so you can list base-domain links and branded links separately.
Troubleshooting
- If verification fails, confirm the CNAME target is exactly
custom.letl.inkwith no leftover A/AAAA record on the same name (some DNS hosts flatten CNAMEs incorrectly). - Do not point a naked apex (
example.com) unless your DNS host supports CNAME flattening and you understand the mail/MX implications. A subdomain is the supported path. - Certificate issuance can take a few minutes after DNS is correct. Reloading the integrations page refreshes status.
