Response

{
  "id": "01957e3a-4b5c-7d8e-9f0a-1b2c3d4e5f6a",
  "to": "+966512345678",
  "templateName": "verification_code",
  "language": "en",
  "category": "AUTHENTICATION",
  "status": "read",
  "failureReason": null,
  "sentAt": "2026-03-08T12:00:03.000Z",
  "createdAt": "2026-03-08T12:00:00.000Z"
}

Status Values

status advances as the provider reports each step. It is not guaranteed to reach read — that depends on the recipient's privacy settings.

Status	Description
queued	Accepted by Arsel, not yet handed to the provider
sent	The provider accepted it and returned a message ID
delivered	Confirmed delivered to the recipient's device
read	The recipient opened the message
failed	The send failed — see failureReason

Template parameters are never returned

parameters is deliberately absent from every response. For an authentication template that field holds the one-time code, and an endpoint that reads codes back out would turn a leaked API key into an account-takeover tool.
