Webhook Payload Formatter

Paste any webhook JSON payload to format, validate, and analyze it. Works with n8n, Zapier, Make, Stripe, GitHub, and any API webhook.

How the Webhook Payload Formatter Works

      
This tool takes raw JSON webhook payloads and formats them with proper indentation for easy reading. It validates the JSON structure, highlights syntax errors with exact position markers, and provides statistics about the payload including depth, key count, and size.


      

        
What Gets Analyzed

        
The formatter parses your JSON using the browser's native JSON.parse(), then re-serializes it with 2-space indentation. It counts total keys, nesting depth, arrays, and payload size in bytes. If parsing fails, it pinpoints the exact character position of the syntax error.

      


      
Webhook Payload Debugging Tips

      
When debugging webhook integrations in n8n, Zapier, or Make, the first step is always inspecting the payload structure. Common issues include missing required fields, unexpected data types (string instead of number), nested objects where flat values are expected, and arrays that should be objects.


      
Common Webhook Payload Formats

      
Most webhook providers send JSON with an event type field and a data object. Stripe uses type and data.object. GitHub uses action with the resource as the top-level key. Shopify wraps everything in the resource name. Understanding these patterns helps you map webhook data to your automation workflows correctly.


      
Minification for Production

      
When sending webhook payloads in your own automations, minified JSON reduces bandwidth and transfer time. The Minify button removes all whitespace and formatting, producing the most compact representation. This is especially useful when storing payloads in databases or passing them through message queues.


      
Privacy and Security

      
All formatting and validation happens in your browser. Webhook payloads often contain sensitive data like API keys, customer information, and payment details. None of this data leaves your device — no server processing, no logging, no storage.
