Note: You can skip this operation if you're using Secure by Default that automatically creates an edge hostname upon activation. This POST operation creates a new edge hostname. As detailed in the sections below, you can use three approaches to secure new edge hostnames: Standard TLS, Enhanced TLS, or a Shared Certificate. You can assign a use case mapping profile to optimize the hostname to serve specific types of traffic. Once the edge hostname is active, you can Update a property's hostnames to assign it to a hostname on a property. After you activate a property, modifying your DNS to map the property hostname to the edge hostname ultimately enables traffic on the property. For details, see Enable traffic for a new hostname. Use the Edge Hostname API (HAPI) to modify edge hostnames, or delete any that aren't currently assigned to an active property configuration.
