Instead of using the default SunLinks URL, you can set up your own custom domain (for example go.yourcompany.com) so your short links use your brand.

​
Add a domain

  1. Go to Settings → Domain.
  2. Click Add Domain.
  3. Enter your domain name (for example links.example.com).
  4. Choose a Default Redirect Type (301 or 302).
  5. Optionally check Use as primary/default domain.
  6. Click Save Domain.

​
DNS setup

1

Create an A record

In your DNS provider, create an A record:
  • Name: your domain name (for example links.example.com)
  • IPv4 Address: the IP address of your SunLinks server
2

Set up a reverse proxy

Use Nginx or Apache to forward traffic from your custom domain to the SunLinks application.
3

Wait for propagation

Wait approximately 15 minutes for DNS changes to propagate.

​
Verify a domain

  1. Go to Settings → Domain.
  2. Click Verify next to your domain.
  3. SunLinks resolves your domain and checks that its A record matches the server’s public IP address.
  4. If verification succeeds, the status changes to Verified (green badge). If not, review your DNS settings and try again.

​
Primary domain

Marking a domain as Primary means all new short links use this domain by default. You can have one primary domain per account.
