Skill Webhook Intake
by Skill: Webhook secure intake in Security & trust
x402 APIPassing, checked 2 h ago
The production ingest path for every incoming webhook: verify the provider signature (GitHub / Stripe / Shopify / Slack, constant-time, replay-window enforced), schema-validate the now-trusted body against the provider envelope, fingerprint the raw bytes for redelivery dedup, normalize the event timestamp to UTC + epoch, and redact PII before anything hits a log. Five pure-CPU tools - the accept-or-reject gate, run on every event.
