Connect a domain without interrupting the store
Your platform subdomain keeps working while a new custom hostname is verified and its certificate is issued.

Add the exact hostname
Use a hostname you control, such as esim.example.com, in Store settings > Domain. Copy the CNAME and any TXT values shown for that record; do not use an example token.
Check both statuses
Refresh the domain status in admin. Ownership and SSL have separate states. Do not make the hostname primary while it is pending, inactive or failed.
Switch and verify
Once hostname, certificate and DNS are active, mark it primary and test a public page over HTTPS. The old platform subdomain redirects public pages to the healthy primary domain.
