Bookings shows the diary. The assistant writes to the same one you are looking at, so there is only ever one version of the day.
What the assistant can do by itself
- Book a free slot in a service you marked bookable.
- Reschedule an existing appointment when the customer asks.
- Cancel one, and offer another time.
It cannot double-book. If two people ask for the same slot, the second is offered the nearest alternative.
Reminders
A reminder goes out before the appointment, on WhatsApp, in the language the customer has been using. Replying to it reaches the assistant like any other message, so “can we make it Thursday?” becomes a reschedule without anyone being called.
Reminders are templates, because they start a conversation rather than continue one. Meta charges for them, and the amount is small.
Booking by hand
You can add, move and cancel appointments yourself. The assistant sees the change immediately and stops offering the slot.
When a customer does not show
Nothing automatic happens. Cancel it so the slot returns, or leave it as a record. Waba91 will not message someone about missing an appointment unless you tell it to.
