  title: FullStory Server Users API
  description: The FullStory Server API is a RESTful API that enables developers to programmatically send user and event data to FullStory. It supports creating and updating individual users, batch importing users, sending server-side events, and batch importing events. The API uses JSON for request and response bodies and authenticates via API keys. Developers can use it to enrich FullStory session data with server-side context that is not available in the browser or mobile app.
