Choosing a subdomain

Please follow the steps to set a custom domain in this order:

1. Choosing a custom domain

2. Initiating the custom domain setup

3. Configuring DNS

Only subdomains can be used to serve your store. It's not possible to use an apex domain.

Here are some examples of what you could and could not choose — just replace example.com with your own domain:

Domain type	Example	Supported?
Apex domain	example.com	❌
www subdomain	www.example.com	✅
Custom subdomain	docs.example.com help.example.com anything.example.com	✅

Once you have chosen your custom domain, you're ready to move onto the next step: Initiating the custom domain setup
