Configure your APIM subdomain at → → .
In your API settings, configure your subdomain. This subdomain will be used for the APIM console, API Developer portal, and Gateway URLs. For example, if your organization's name is My Org, you can use 'myorg' as the subdomain. The subdomain has a 200-character limit (alphanumeric only). Be sure to choose your subdomain name carefully, as it cannot be easily reconfigured once it is set.
Your subdomain name will be reflected in your APIM console URL, Developer portal URL, and Gateway URL. To reconfigure your subdomain, you must create a support ticket.
You can also configure your service account email address. This email address will own all APIs created in your organization and receive all email notifications.
