    Best-effort AsyncAPI 2.6 description of the FreshBooks Webhooks (Callbacks API)
    surface. FreshBooks delivers webhook notifications as HTTP POST requests with an
    `application/x-www-form-urlencoded` body whenever a subscribed event occurs on
    a FreshBooks account. Each delivery is signed with an HMAC-SHA256 signature
    derived from the verifier code returned at callback registration.

    Generated from public documentation at https://www.freshbooks.com/api/webhooks;
    not an official spec.

    description: |
      The HTTPS endpoint registered by the subscriber when creating a FreshBooks
      callback. FreshBooks POSTs event notifications to this URL. The endpoint
      must respond with a 2xx status within 10 seconds.

    description: |
      Single delivery channel used by FreshBooks for all callback notifications.
      The specific event is identified by the `name` form field in the body
      (e.g. `invoice.create`). FreshBooks signs every delivery with an
      `X-FreshBooks-Hmac-SHA256` header computed over the UTF-8 encoded JSON
      string of the request parameters using the verifier code as the secret.

        FreshBooks publishes a single message envelope containing the event

        `X-FreshBooks-Hmac-SHA256` signature before processing.
