From the Services page backend services can be registered and managed.
A backend service is basically an unmanaged REST endpoint fronted by the API Platform's API Gateway.
A service registered in this page can be referenced from the API implementation page that way preventing a backend endpoint URLs to be manually typed every time an API is created.
This page is only available but from version 17.3.x onwards.
Management portal–services page
Once a service is created, it can be edited just clicking over it. This will take the user to the service settings page described subsequently.
