Reliable event delivery with signatures you can trust.
Logic emits a webhook for every state transition: payment confirmed, invoice paid, refund issued, payout settled, dispute opened. Every payload is signed, retried, and replay-protected.
Signed payloads
Every request carries an HMAC-SHA256 signature over the raw body. Verify with the signing secret shown once when you create the endpoint.
Retries
Failed deliveries retry with exponential backoff for up to 72 hours. Inspect every attempt, response code, and latency in the dashboard.
Replay protection
Events carry a monotonic ID and an issued-at timestamp. Reject anything older than five minutes and you have replay protection by default.
