WhatsApp Business API for salons: setup, rules and real costs

The app is fine until these start happening to a salon:

• No-shows leave chairs empty and revenue lost.
• Booking calls interrupt service time. Your stylist stops mid-blowout to answer "Do you have a slot tomorrow at 3?" WhatsApp booking does this silently.
• Clients leave happy and never rebook. They loved the cut. Nobody booked them in for the next one, so the chair sits empty and they drift to whoever has a slot.

The app cannot send on a trigger, share one number across staff, or read your records. The API can. And customers keep asking the same things: clients ask whether their stylist is free on Saturday, how long a colour or keratin takes, what a service costs for their hair length, and whether they can move an appointment.

• A verified Meta Business account in the salon's legal name, backed by a registration, GST or utility document.
• A number not active on the WhatsApp app — your current one works once it is removed from the app.
• A display name matching the business, and a website or public page Meta can check.
• Opt-in from every customer you message first. Booking is the moment: clients already give their number for the appointment, so asking to message them on WhatsApp is a small step.

Meta asks that every business can show where a customer's opt-in came from. For a salon that is simple to do and easy to forget: note, against each client, whether they agreed to appointment messages (almost everyone who books), to offers (a smaller group), and how — at checkout, by a button on WhatsApp, on the booking form. When a client says "stop", record that too, and make sure it stops offers without stopping the reminder for the appointment they still have. A clean record is what lets you message confidently, and what protects the number if a client ever reports you.

1. Connect the number through Meta's embedded signup inside Reputoo, and submit business verification — you can start sending within Meta's starting limit while it is reviewed.
2. Get your first templates approved for the 2 routine messages listed below; anything outside a customer's 24-hour reply window must be a template.
3. Wire the triggers to your records. What to connect: A salon booking system with stylist calendars; per-stylist availability is what makes WhatsApp booking actually work.
4. Put staff on one shared inbox, with conversations assigned so two people never answer the same customer.

A salon is not one calendar. It is one calendar per stylist, each with different skills, days off and hours — and clients book the person as much as the service. The API does not know any of this on its own; your booking system does. Before automating a single confirmation, set up:

• Services with real durations. A men's cut and a global colour cannot share a 30-minute slot. Put the time each service actually takes, including processing and blow-dry.
• Which stylist does which service. Not every stylist does keratin or bridal; the booking should only offer those who do.
• Working hours and days off per stylist, so a Tuesday booking never lands on a stylist's day off.
• Buffers between long services, for cleaning and a breath.

With that in place, appointment booking can confirm the right person for the right length of time — and every template above fills in from the booking, not from someone typing it.

Seven of nine are utility messages. On Meta's July 1, 2026 India rate card a utility message costs ₹0.115 and a marketing message ₹0.8631. A salon with 25 appointments a day sending a confirmation and a reminder for each sends about 1,500 utility messages a month — around ₹173 before GST. A monthly offer to 800 opted-in clients adds ₹690. Keep offers out of the confirmation and reminder templates, or Meta will classify them as marketing too.

A no-show on a 20-minute cut costs a salon 20 minutes. A no-show on a three-hour colour or a keratin treatment costs a stylist's afternoon, and often the product mixed in advance. That is why many salons take a deposit for long services, and WhatsApp is the easiest place to collect it.

• Send the payment link in the booking confirmation, with the amount and the policy in one sentence: "A ₹500 deposit holds your slot and is adjusted in your bill."
• Hold the booking as provisional until the deposit arrives, and say by when.
• State the cancellation rule plainly — how much notice gets the deposit back — in the confirmation, not in small print elsewhere.
• Leave exceptions to the owner. A regular with a family emergency should hear from a person.

(The amount is an example; set your own.)

Two messages salons often skip are the ones clients value most. Hair-colour manufacturers advise a skin allergy test 48 hours before colouring; a reminder two days ahead — "please drop in for a quick patch test before Saturday's colour" — protects the client and the salon. After a chemical treatment, a short aftercare message — how long to wait before washing, which shampoo to use, exactly as your stylist advised for that product — saves the treatment and the complaint that follows a ruined one.

Both are utility messages when they stick to the appointment. Adding "and a discount on our aftercare range" changes that — send product offers separately, to clients who opted in to offers.

Prepaid packages — six blow-dries, a monthly grooming plan, a bridal package paid in instalments — are good for a salon's cash flow and easy to lose track of. A short utility message after each visit ("3 of 6 blow-dries used, valid till 30 November") answers the question clients would otherwise ask at the counter, and a reminder before expiry saves the argument about an unused session. Keep these strictly factual: the balance, the validity and how to book the next session. A renewal offer belongs in a separate marketing message to clients who opted in.

A stylist off sick on a Saturday can mean a dozen bookings to move before the salon opens. Done by phone, it takes the receptionist the whole morning and still misses people. Done with one utility template, each affected client gets a message with three buttons — [Another stylist, same time] [Priya, another day] [Cancel] — and the calendar updates as they answer. The clients who do not reply are the only ones who need a call.

Meta rates every number on how customers react. For salons, the risk is usually messaging the whole contact list about something only some of them asked for. Send reminders only to people with a booking or order, promotions only to people who opted in to them, and never use a bulk-sender tool on the ordinary app — that is the route to a banned number. The full list of what Meta checks is in our WhatsApp Business API guide.

Two situations come up in almost every growing salon. Branches: either one number for the whole salon, with bookings routed to the right branch, or one number per branch under the same business account — most salons start with one number and split only when branches run separately. Stylists: many clients message their stylist's personal WhatsApp, which means the salon has no record, no consent and no booking when that stylist leaves. Moving those conversations to the salon's number, answered in a shared inbox where the stylist still replies, keeps the relationship personal and the client with the salon.

1. Week 1 — set up and connect. Services, durations and stylist calendars in the booking system; the number moved to the API; confirmation, reminder and reschedule templates submitted.
2. Week 2 — confirmations and reminders on. Every booking, however it was made, gets the same confirmation and a reminder the day before with buttons.
3. Week 3 — booking by WhatsApp. Clients can ask for a slot in chat and get one confirmed without a call. Stylists move client chats from personal phones to the shared inbox.
4. Week 4 — aftercare, patch tests and deposits. Then, and only then, the first rebooking message to clients who opted in.

• Every service has a real duration and a list of stylists who do it.
• Every stylist's hours and days off are in the calendar.
• Confirmation, reminder, reschedule, patch-test and aftercare templates are approved and contain no offers.
• The deposit and cancellation policy is one clear sentence in the confirmation.
• Clients on the offers list opted in to offers, not just to reminders.
• Someone owns the inbox during opening hours, and stylists know how to reply from it.
