Documentation

  • New page Callbacks — incoming SMS to a dedicated number, Viber 2 Way replies, and the delivery report sent by email. None of these notifications were documented before.
  • Webhook — added the request_id, reply and duration fields; id and msg_id are strings, not numbers; added the delivery rules (one attempt, no retries, 5-second timeouts) and an example of a rejected message.
  • Verify (OTP) — documented the webhook that reports a rejected request.
  • Request examples on the JSON API pages now come with ready-to-run cURL, PHP, Python and Node.js snippets.
  • The receive, delete and price commands of the HTTP API were described as send by mistake.
  • Wap-Push is no longer documented.
