​
Custom Domains

Use your own domain for short links instead of the default linqu.id.

​
Setup

​
1. Add Your Domain

  1. Go to Settings > Domains
  2. Click Add Domain
  3. Enter your domain (e.g., go.yourcompany.com)

​
2. Configure DNS

Add a CNAME record pointing to Linquid:
TypeNameValue
CNAMEgoproxy.linquid.io
For apex domains (no subdomain), use an A record or ALIAS if your DNS provider supports it.

​
3. Verify

Click Verify Domain in the dashboard. Verification typically takes a few minutes.

​
4. SSL Certificate

SSL is automatically provisioned via Cloudflare. Your domain will be secured with HTTPS.

​
Using Custom Domains

​
Set as Default

Make your custom domain the default for new links:
  1. Go to Settings > Domains
  2. Click the star icon next to your domain
Choose a domain when creating a link: 
{
  "destinationUrl": "https://example.com",
  "domainId": "domain_abc123"
}
Or use the system domain field: 
{
  "redirectDomain": "go.yourcompany.com"
}
With a custom domain, your links become: 
https://go.yourcompany.com/promo2024
Instead of: 
https://linqu.id/promo2024

​
Multiple Domains

You can add multiple custom domains:
PlanDomain Limit

Pro10
EnterpriseUnlimited
Use different domains for:
  • Different brands
  • Different campaigns
  • Geographic targeting

​
DNS Configuration Examples

go.yourcompany.com CNAME proxy.linquid.io

​
Apex Domain

If using Cloudflare: 
yourcompany.com CNAME proxy.linquid.io (with CNAME flattening)
If not using Cloudflare, check if your provider supports ALIAS records.

​
Verification Issues

  • Check DNS propagation (can take up to 48 hours)
  • Verify CNAME is correct
  • Ensure no conflicting records
  • Wait up to 24 hours for certificate provisioning
  • Ensure domain points to Linquid
  • Check for CAA records blocking Cloudflare

​
Removing a Domain

  1. Go to Settings > Domains
  2. Click the delete icon
  3. Confirm removal
Removing a domain will break all links using that domain. Update your links first or redirect the DNS elsewhere.
