Error Handling

All tools return errors in a consistent format:

{
  "error": {
    "code": "INVALID_PARAMETER",
    "message": "Invalid webhook ID format",
    "details": {
      "parameter": "webhookId",
      "value": "invalid",
      "expected": "Format: wh_xxx"
    }
  }
}

​
Common Error Codes

CodeDescription
INVALID_PARAMETERInvalid parameter value
NOT_FOUNDResource not found
PERMISSION_DENIEDNo access to resource
RATE_LIMITEDToo many requests
INTERNAL_ERRORServer error

​
Best Practices

  1. Use filters effectively - Always filter by webhookId when debugging specific integrations
  2. Limit results - Start with smaller limits and increase if needed
  3. Check error details - The analysis tools provide actionable recommendations
  4. Monitor stats regularly - Use get_webhook_stats to track webhook health
  5. Combine tools - Use search tools to find issues, then analyze tools for details

​
Rate Limits

Tools are subject to the following limits:

  • Maximum 60 tool calls per minute
  • Maximum result size of 1MB per call
  • Search results capped at 100 items
