description: Formpaste provides a single webhook event for each delivered, non‑spam form submission.
events:
- event: submission.received
  description: Fires for each delivered, non‑spam submission.
delivery:
  signature: HMAC‑SHA256 over "${timestamp}.${rawBody}" using the form’s signing secret (whsec_…) and sent in the X-Formpaste-Signature header
    (prefixed with "sha256=")
  retries: If the endpoint does not return a 2xx response, Formpaste retries with exponential backoff (≈10 s → 60 s → 5 min → 30 min) up to 5
    attempts total; a 4xx response is treated as permanent and not retried.
note: Only HTTPS URLs are accepted; one webhook URL per form; free plans cannot configure webhooks.
