WhatsApp messaging integration

Hi

I want to integrate whatsapp to a cloud-based taxi booking system with an open API.

Currently the booking system sends messages by SMS via an integrated android app I believe it uses web hooks to do so.

These SMS are triggered by different actions made on the booking system. These messages vary depending on the on these triggers/actions.

For Example- When booking is made, a booking confirmation is sent with clients name, system generated Booking ID, Booking Time. When driver arrives another message is sent with driver detail tracking link and so on.

I want to redirect those messages to be sent through WhatsApp rather than SMS. Send SMS only if WhatsApp is not available.

The booking system has an open API which I believe it straight forward to integrate, I can send you the link if required.

I want to be able to change the message templates if i need to.

If you need more information please do not hesitate to ask.
