  title: Fastly Domain Management API
  description: >-
    The Fastly Domain Management API allows developers to programmatically
    associate domain names with Fastly services. Domains serve as the entry
    point for traffic routed through Fastly's edge network. The API supports
    adding, listing, and removing domains from service versions, checking
    domain DNS configurations, and validating that domains are correctly
    pointed to Fastly. It is essential for managing the routing configuration
    that connects end-user requests to the appropriate Fastly service.
