Fullstory Logging API

Implementation Files: This document covers core concepts. For code examples, see:

• SKILL-WEB.md — JavaScript/TypeScript (Browser)
• SKILL-MOBILE.md — iOS, Android, Flutter, React Native

Overview

Fullstory's Logging API allows developers to send log messages directly to Fullstory sessions. These logs appear in the session replay, providing valuable context for debugging user issues, tracking application state, and understanding user workflows—without cluttering the device's console or logging systems.

Key use cases:

• Error Context: Log errors with stack traces viewable in replay
• Application State: Record important state changes
• Debugging: Add contextual information during development
• Audit Trail: Log significant user actions
• Support Context: Add logs that support teams can see in sessions
