A short link on a custom domain (branded link) is a shortened link that uses your own subdomain, for example go.thuonghieu.vn/khuyen-mai. Recipients see your brand instead of the service name, so they trust it and click more.
What's included
Custom domain on 1Go.vn
Two DNS records
A CNAME pointing the subdomain to cname.1go.vn and a TXT _1go-challenge record proving you own the domain.
Automatic SSL
Once verified, the HTTPS certificate is issued and renewed automatically, with no action needed.
Clear status
Each domain shows whether it is waiting for DNS, issuing SSL, active or failing, along with instructions to fix it.

Shared with bio pages
Attach a custom domain to your bio page with the same CNAME and TXT records.
API key scoping
Limit an API key to specific domains so a script only touches the domains it is allowed to.
How it works
Connect a custom domain
- Go to Domains, click Add domain and enter the subdomain, for example go.thuonghieu.vn.
- Add the CNAME and TXT records 1Go shows at your DNS provider.
- Wait for 1Go to verify the domain and issue SSL, then pick that domain when you create a link.
