Webhook Testing Best Practices

1. Test Different HTTP Methods

Verify your workflow handles GET, POST, PUT, DELETE requests correctly.

2. Validate Data Formats

Ensure JSON, XML, and form data are processed as expected.

3. Test Error Scenarios

Configure custom error responses to test error handling.

4. Monitor Performance

Track response times and identify performance bottlenecks.

Sample Webhook Configuration

// n8n HTTP Request Node Configuration
{
  "method": "POST",
  "url": "https://webhook.site/your-unique-id",
  "headers": {
    "Content-Type": "application/json",
    "X-API-Key": "{{$json.api_key}}"
  },
  "body": {
    "timestamp": "{{$json.timestamp}}",
    "event_type": "{{$json.event}}",
    "data": {
      "user_id": "{{$json.user_id}}",
      "action": "{{$json.action}}",
      "metadata": "{{$json.metadata}}"
    }
  }
}

This configuration sends structured data to Webhook.site for testing and validation.
