Log Module

The Log Module outputs webhook payloads to stdout. This is useful for debugging and development.

Configuration​

{
    "log_webhook": {
        "data_type": "json",
        "module": "log",
        "module-config": {
            "pretty_print": true,
            "redact_sensitive": true
        },
        "authorization": "Bearer token"
    }
}

Module Configuration Options​

OptionTypeDefaultDescription
pretty_printbooleanfalseEnable JSON formatted output with indentation
redact_sensitivebooleantrueRedact sensitive data like passwords, tokens, API keys

Security Features​

Sensitive Data Redaction​

When redact_sensitive is true (default), the following keys are automatically redacted:

  • password, passwd, pwd, secret
  • token, api_key, apikey
  • access_token, refresh_token
  • authorization, auth, credential
  • private_key, session, cookie
  • database_url, connection_string
  • And more...

Example output with redaction:

{
  "event": "user.created",
  "api_key": "[REDACTED]",
  "data": {
    "user_id": 123,
    "password": "[REDACTED]"
  }
}

Output Limits​

  • Maximum output length: 10,000 characters (prevents DoS)
  • Maximum recursion depth: 10 levels
  • Log injection prevention: Newlines and control characters are sanitized

Output Modes​

Standard Mode (default)​

config: {'data_type': 'json', 'module': 'log', ...}
headers: {'content-type': 'application/json', 'authorization': '[REDACTED]'}
body: {'event': 'test', 'data': 'example'}

Pretty Print Mode​

================================================================================
WEBHOOK RECEIVED
================================================================================

Headers:
{
  "content-type": "application/json",
  "authorization": "[REDACTED]"
}

Payload:
{
  "event": "test",
  "data": "example"
}
================================================================================

Features​

  • Simple stdout output
  • No external dependencies
  • Sensitive data redaction (enabled by default)
  • Pretty print mode for debugging
  • Log injection prevention
  • Output size limits
  • Circular reference handling

Example: Development Debugging​

{
    "debug_webhook": {
        "data_type": "json",
        "module": "log",
        "module-config": {
            "pretty_print": true,
            "redact_sensitive": false
        }
    }
}
Security

Only set redact_sensitive: false in development environments. In production, always use the default true to prevent sensitive data exposure in logs.
