Configuration

This guide explains how to configure the Composio SDK using environment variables and initialization options.

Environment Variables

The SDK supports several environment variables for configuration:

Core Configuration

• COMPOSIO_API_KEY: Your Composio API key

  • Required for authentication
  • Can be obtained from Composio Dashboard
  • Can also be set via SDK initialization or user config file

• COMPOSIO_BASE_URL: Custom API base URL

  • Optional
  • Default: https://backend.composio.dev
  • Use this to point the SDK to a different API endpoint

Logging Configuration

• COMPOSIO_LOG_LEVEL: Controls the verbosity of SDK logs
  • Values: silent, error, warn, info, debug
  • Default: info
  • Hierarchy (from highest to lowest priority):
    • silent: No logs
    • error: Only critical errors
    • warn: Warnings and errors
    • info: General information, warnings, and errors
    • debug: Detailed debugging information

Development and Testing

• NODE_ENV: Environment mode

  • Values: development, production, test
  • Affects:
    • Telemetry collection (disabled in development/test)
    • Error handling verbosity
    • Version check notifications

• DEVELOPMENT: Development mode flag

  • Set to any value to enable development mode
  • Enables additional debugging features
  • Shows more verbose logs

• CI: CI environment flag

  • Set to any value to indicate CI environment
  • Affects certain behaviors like version checks

Telemetry

• COMPOSIO_DISABLE_TELEMETRY: Disable telemetry collection
  • Set to "true" to disable
  • Default: "false"
  • Alternative to allowTracking initialization option

SDK Initialization Options

When initializing the SDK, you can provide configuration through the constructor:

const composio = new Composio({
  apiKey: 'your-api-key', // Override COMPOSIO_API_KEY
  baseURL: 'custom-url', // Override COMPOSIO_BASE_URL
  allowTracking: false, // Disable telemetry
  allowTracing: true, // Enable tracing
  provider: new CustomProvider(), // Custom provider
  host: 'mcp', // host where the sdk is being used
});

Configuration Priority

When multiple configuration sources are present, the SDK follows this priority order:

1. Constructor parameters
2. Environment variables
3. User config file
4. Default values

Examples

Development Setup

# Development environment with debug logging
export NODE_ENV=development
export COMPOSIO_LOG_LEVEL=debug
export COMPOSIO_API_KEY=your-api-key

Production Setup

# Production environment with minimal logging
export NODE_ENV=production
export COMPOSIO_LOG_LEVEL=error
export COMPOSIO_API_KEY=your-api-key

Testing Setup

# Test environment with telemetry disabled
export NODE_ENV=test
export COMPOSIO_DISABLE_TELEMETRY=true
export COMPOSIO_API_KEY=your-test-api-key

Best Practices

1. Environment-specific Configuration

   • Use different log levels for different environments
   • Enable detailed logging in development
   • Use minimal logging in production

2. Security

   • Never commit API keys to version control
   • Use environment variables or secure secrets management
   • Consider using different API keys for different environments

3. Telemetry

   • Enable telemetry in production for better support
   • Disable telemetry in development and testing
   • Use custom telemetry transport for specific needs

4. Error Handling

   • Set appropriate log levels for error tracking
   • Use debug level during development
   • Use error or warn level in production
