  title: Split Admin Segments API
  description: The Split Admin API is a REST API that enables programmatic management of workspaces (projects), environments, traffic types, attributes, users, groups, API keys, and change requests within the Split platform (now Harness Feature Management and Experimentation). The API uses resource-oriented URLs, returns JSON responses, and requires Admin API keys for authentication. All endpoints are prefixed with /internal/api/v2 on the api.split.io host.
