FAQ

How does payload tracking work?
You point your webhook sender to our generated endpoint. We capture every payload, extract the schema, and diff it against previous versions automatically.
What counts as a breaking change?
Removed fields, changed field types, renamed required keys, and structural reorganizations are all flagged as breaking. New optional fields are non-breaking.
Can I export the payload history?
Yes. Every captured payload and its diff report is available via our API and can be exported as JSON at any time.
