delivery:
  signature: Every delivery carries `webhook-id`, `webhook-timestamp`, and `webhook-signature` headers per the open Standard Webhooks specification
    (HMAC‑SHA256 over the message id, timestamp, and payload). Inbound sources also support bespoke verifiers for Stripe, GitHub, Shopify, Slack,
    Twilio and generic HMAC‑SHA256.
  retries: 'Failed deliveries are retried automatically with exponential backoff up to 5 delivery attempts (backoff intervals: 10 s, 30 s, 2 min,
    10 min); any still‑failing deliveries end up in a dead‑letter queue.'
