  title: Statsig Client SDK Audit Logs Segments API
  description: The Statsig Client SDK API provides endpoints that power Statsig's client-side SDKs for JavaScript, React, React Native, iOS, Android, Unity, and other platforms. Client SDKs use Client-SDK Keys that are safe to embed in mobile apps and front-end web applications. They access the initialize endpoint to retrieve all evaluated gates, configs, and experiments for a given user, and the log_event endpoint for sending analytics events. The SDKs handle local evaluation, caching, and automatic error handling for performant client-side feature flagging.
