About JSON formatting
Why prettify webhook payloads?
Webhook providers send minified JSON. Prettifying makes nested structures readable when debugging — you can quickly spot field names, values, and nesting depth without squinting at a single long line.
Does formatting change the data?
No. Prettify and minify only change whitespace. The parsed JSON value is identical — key order is preserved as returned by the parser. Numbers, strings, and booleans are unchanged.
2 spaces vs 4 spaces — which should I use?
Two spaces is the most common convention in JavaScript and API docs. Four spaces is common in Python and some enterprise style guides. Use whatever matches your project's linter — the data is the same either way.
Inspecting webhook payloads manually?
HookDeploy captures every webhook, stores it with full history, and lets you inspect, replay, and route it — without writing any code.
