To set up the API Management capability within SAP Integration Suite, you must provide a virtual host as part of the initial configuration step. The virtual host is a host alias that identifies your organization and is used as the base URL of your API proxies. For example, if your virtual host is myorg, your API proxy URL will look like this: https://myorg.apimanagement.hana.ondemand.com/<api-name>. The virtual host can be changed later in the API portal settings. Reference: Setting Up API Management Capability | SAP Help Portal, Virtual Hosts | SAP Help Portal
