What fields should a record in the SMS notification service contain?

The notification service record for SMS usually should contain the following fields:

• id — unique notification identifier.
• phone_number — recipient's phone number in international format.
• message — text of the SMS message.
• status — current sending status (e.g., "pending", "sent", "failed").
• created_at — date and time the record was created.
• sent_at — date and time the message was sent (if sent).
• retry_count — number of sending attempts.

  "message": "Your confirmation code: 1234",
  "status": "pending",
  "created_at": "2024-06-01T12:00:00Z",
  "sent_at": null,

}
