WhatsApp booking is the written thread in which a guest names a woman, a length and an address, and which confirms the booking once she accepts it.
There is no form to fill in and no call to make. A reservation from the roster is arranged by message, on WhatsApp or, for guests who prefer it, on Telegram, and the hour is settled in writing in that same thread.
Because this catalogue is organised around people, the most useful first word is a name. Four details after it make a complete request: the length, read from the rates table in her roster profile; the time, whether now or a date and hour; the place, a hotel or apartment and the rough area; and whether this is a first booking with the house. Lucie, two hours, tomorrow at nine, apartment in the Jordaan, first time: a line like that leaves nothing to ask. The reply will quote her two-hour fee and ask for half of it as the deposit, since a first reservation always carries one.
The confirmation names the woman, the fee, the deposit where one applies, and the timing. Payment details for a deposit appear there and nowhere else, and only once the booking has been accepted. Should a payment demand turn up ahead of acceptance, or from an unfamiliar number, it did not come from the house; pay nothing, and mention it in the thread.
The thread doubles as the record. When a guest needs to move a booking, which costs nothing once when asked with more than a day's notice, correct a room number or check whether a chosen woman is still free, the change sits in writing beside the original request, with a timestamp both sides can scroll back to. That protects the guest from a misread figure and the woman from a half-remembered address.
Some guests hesitate to put a first message in writing at all. The replies come in the same plain register and keep the conversation to the booking. The booking page follows a reservation from its opening line to the knock, and booking by name covers the case where she is already taken.
