Builds the producer side of webhooks — you dispatch signed events to customers' HTTPS endpoints. Sign every payload with HMAC-SHA256 over "{timestamp}.{rawbody}" in a versioned signature header with per-endpoint secrets and rotation overlap; deliver at-least-once with exponential backoff + jitter over hours, then dead-letter with manual replay; send thin events (id, type, ts, minimal data) so consumers re-fetch the resource; isolate delivery per endpoint so one broken target can't stall everyone; ship a stable event id + sequence number so consumers can dedup and not assume order; verify endpoints on registration; and lock down the target URL against SSRF (HTTPS-only, block internal/link-local/metadata IPs, re-resolve on each send). Use when your service must reliably and verifiably push events out to third-party subscribers.
