      Events Loops sends to your configured webhook endpoint when certain events
      happen in your account. Configure an endpoint in Settings → Webhooks. Each
      account supports one webhook endpoint. Events are signed with
      `webhook-id`, `webhook-timestamp`, and `webhook-signature` headers and
      delivered at a maximum rate of 10 per second. See
      https://loops.so/docs/webhooks for setup, verification, and payload
      details.
