How custom domains work

Custom domains use

to point requests made to your subdomain to your router endpoint URL. Custom domains run on
global network.

Custom domains setup

Setup includes two steps:

  1. Setting up a CNAME record in your DNS provider.
  2. Opening a ticket with Apollo support to enable your CNAME.


Custom domains will be available through self-service in later in 2024. In the meantime, you must open a support request to enable your CNAME with Apollo.

Setup a CNAME

CNAME records are assigned at the variant level, so you must set up a separate CNAME record for each variant that requires a custom domain.

Using an existing CNAME

If you already have a CNAME record for the custom domain you want to use,

before making any changes. We'll guide you through remapping from a different host to the subdomain.

Open a support ticket

Next, open a support ticket requesting Apollo to enable your new CNAME. You can open a ticket by clicking the ? icon in the top right of

and selecting Contact Support.
