  title: Fastly Services API
  description: >-
    The Fastly Services API allows developers to create, configure, and manage
    Fastly CDN services and their versions programmatically. Services are the
    primary organizational unit in Fastly, representing a configuration that
    maps domains to backends. The API supports creating service versions,
    activating and deactivating configurations, cloning versions, and managing
    the complete lifecycle of a CDN service deployment.
