Frequently asked questions
My payload is a JSON string inside a field. Can it read that?
Yes — the viewer detects escaped JSON in string values and lets you expand it as a nested document.
Does this receive live webhooks?
No. It is a viewer for a payload you already have, not an endpoint that captures deliveries. Paste the body your provider logged or the request your server recorded, and this will parse and lay it out. Nothing is uploaded and no endpoint is created.
Why does my payload fail to parse?
Most often it is not JSON at all: form-encoded bodies and XML are both common for webhooks and look superficially similar in a log. The other frequent cause is a payload copied from a terminal that wrapped or truncated it. The error names the position it stopped at.
How do I check a webhook signature?
Not here, because it needs your signing secret and the exact raw body, byte for byte, before any parsing. Most providers sign the raw request body, which means computing the HMAC on your server before the body is deserialised. Reformatting a payload, as this page does for readability, would invalidate the comparison.
