  description: The Segment Public API allows developers to programmatically manage
    Segment workspaces and their resources. It supports full CRUD operations for sources,
    destinations, warehouses, tracking plans, and catalog entries. The API follows
    REST conventions with standard HTTP methods and predictable resource-oriented
    URLs. It is available for Team and Business tier customers and is the recommended
    API going forward, replacing the older Config API.

  description: The Segment HTTP Tracking API enables developers to record analytics
    data from any website or application by sending HTTP requests directly to Segment
    servers. It supports identify, track, page, screen, group, and alias calls, and
    Segment routes the collected data to configured destinations. The API accepts
    batch requests up to 500 KB and requires each payload to include a userId or anonymousId.
    It is a server-side alternative to Segment's client-side SDKs.

  description: The Segment Profile API provides a single endpoint to read user-level
    and account-level customer data from Segment Unify. Developers can query the entire
    user or account object programmatically, including external IDs, traits, and events
    that make up a user's journey. The API uses basic authentication and typically
    delivers p95 response times under 200ms for the traits endpoint. It is commonly
    used for real-time personalization and customer data retrieval.

  description: The Segment Config API allows programmatic management of Segment workspaces,
    sources, destinations, and other configuration resources. It provides endpoints
    to list workspace sources and destinations, create or delete destinations, and
    manage tracking plans. As of early 2024, Segment has stopped issuing new Config
    API tokens and recommends migrating to the Public API for access to the latest
    features. The Config API remains functional for existing users but is no longer
    actively developed.

  description: The Segment Pixel Tracking API provides a way to collect analytics
    data using image pixel requests, which is useful in environments where JavaScript
    cannot execute, such as email clients. It supports identify, track, page, screen,
    group, and alias calls through pixel endpoints under the api.segment.io domain.
    This API is particularly suited for tracking email opens, ad impressions, and
    other contexts where embedding a tracking pixel is the only viable data collection
    method.
