TeleBooking
Booked, arriving, leaving — said before they have to ask.
For hotels, clinics, venues and anybody who keeps a room or a slot: the confirmation when it is booked, the message the evening before, the code at check-in and the reminder at check-out. A reminder counts back from the arrival rather than from the booking, which is the difference between "tomorrow" meaning tomorrow and meaning the moment somebody pressed book.
For a business
One line in your property system becomes every message a guest gets, in your words and from your sender ID.
Build on it
Every endpoint sits under /api/v1/booking, and every agent tool is
named telenaas_telebooking_*. A key scoped to TeleBooking reaches those and nothing else — reads included.
What it is billed on
telebooking.message — carried media, not seats. Adding somebody to the team does not add to the bill.
