  title: Contentstack Personalize Management API
  description: >-
    The Contentstack Personalize Management API provides programmatic control
    over the resources in a Contentstack Personalize project, including
    Attributes, Audiences, Events, and Experiences. Developers can use this API
    to create and manage audience segments based on user attributes and
    behavioral events, and to configure personalized content experiences for
    those segments. It is a REST API that follows standard CRUD conventions and
    is intended for use in headless personalization workflows where content
    targeting logic needs to be managed programmatically or integrated with
    external data platforms.
