WhatsApp for Nueva EPS members. With Arbol, on your organization's number.
How it works
The Nueva EPS member writes on WhatsApp to your organization's number, at any hour.
The assistant asks for the Nueva EPS order and authorization before offering a slot.
It books on your calendar and confirms the appointment on WhatsApp, with the instructions.
The day before, it sends a reminder; if they can't make it, it reschedules and offers the slot to the waiting list.
