Is there a service that allows you to send SMS, WhatsAPP and Viber messages API?

Good day, ladies and gentlemen.
Tell me, is there a service through which you can send SMS, WhatsAPP and Viber? You need to make a confirmation of registration and order so that the user can choose where to send the message, SMS, WhatsAPP or Viber. Separately for SMS there are SMS and Viber, Whatsapp is separately. But all at once could not find.
Can was at whom similar experience?
