Restaurants use the WhatsApp Business API for reservations, order updates, guest questions, promotions and WhatsApp calling. This guide shows what to send, what each message costs after Meta's October 2026 pricing changes, and how Telnyx brings messaging, voice and AI together on one number.
How restaurants use the WhatsApp Business API
A memorable dining experience isn't shaped by the meal alone. It's shaped by every interaction around it: the booking, the reminder, the question about allergens, the order update, the thank-you afterwards.
Guests reach out in whatever way suits them at the time. One books online and gets a confirmation by SMS, another asks about allergens on WhatsApp, another calls to move a booking, and a regular replies to your email newsletter. Being easy to reach on all of them is part of good hospitality.
The WhatsApp Business API brings your restaurant to an app many guests already use every day. They can confirm a reservation, ask about outdoor seating, change the time of a booking or check on a catering order in one familiar thread, with every interaction kept connected.
Some conversations still work better by voice: planning a private event, a same-day booking, or helping a guest with accessibility needs. With Telnyx, the same business number handles WhatsApp messaging, WhatsApp calls, SMS and regular phone calls, so you can meet guests on whichever channel they choose, all from one platform.
Explore Telnyx WhatsApp Business API to bring messaging, voice and AI together on one number for your restaurant.
WhatsApp Business API use cases for restaurants
The WhatsApp Business API helps you stay in touch with guests at every stage, from the first inquiry to repeat visits. Instead of one-way notifications, you can run two-way conversations that make it easy for guests to find information, take action and come back.
Which message type is this, and what will it cost?
Pick the message you are about to send to see how Meta bills it.
Whether guests are updating a reservation, browsing today's specials or finding your restaurant, it all happens in the same WhatsApp conversation.
Each use case maps to a Meta message type, and the type sets the price. Messages you start (confirmations, reminders, promotions) must use a template Meta has approved. Replies to a guest inside the 24-hour window after they message you can be free-form.
Reservations
The reservation experience often shapes a guest's first impression of your restaurant.
Send a confirmation the moment a guest books and a reminder the day before, both as utility templates. Add buttons so guests can confirm, change or cancel in one tap. If plans change, they reply in the same chat instead of hunting for your phone number.
Example confirmation (utility template):
Hi {{1}}, your table for {{2}} at {{3}} is confirmed for {{4}} at {{5}}. Need to change it? Tap below. [Change booking][Cancel] |
Example reminder (utility template):
See you tomorrow at {{1}}, {{2}}. Your table for {{3}} is ready. Running late? Just reply here. [I'll be there][Change time] |
Order updates
For takeaway and delivery, timely updates matter as much as the food. Tell guests when an order is confirmed, being prepared, ready for collection or out for delivery, and send the receipt in the same chat. These are utility templates, and they cut down the "where's my order?" calls during a busy service.
Your order #{{1}} is ready for pickup at {{2}}. Show this message at the counter. |
Guest questions
Guests often have questions before they decide to book: dietary requirements, private dining, catering, accessibility, parking, opening hours. On WhatsApp they get an answer without waiting on hold. Your answers are service replies: free-form messages inside the 24-hour window, with no template needed. Send a menu PDF, a map pin or photos of the private room in the same thread.
Loyalty and promotions
The guest journey doesn't end when the meal does. Seasonal menus, birthday offers, loyalty rewards, feedback requests and invitations to exclusive events all go out as approved templates. Building on a conversation you already have keeps them personal and encourages repeat visits.
Anything promotional is a marketing template and goes only to guests who have opted in. Keep promotional lines out of your confirmations and reminders: Meta treats a template with promotional content as marketing, which costs about 7x more than utility in the US.
A reservation on WhatsApp, step by step
Here's one guest's booking from start to finish, with the message type and Meta's US price at each step.
| When | What you send | Message type | Meta cost (US) |
|---|---|---|---|
| Guest books online | Confirmation with Change and Cancel buttons | Utility template | $0.0034 |
| Day before | Reminder with Confirm and Change buttons | Utility template | $0.0034 |
| Guest replies "Can we make it 8pm?" | Your reply and the new time | Service reply | Free for the first 1,000 a month, then $0.0034 |
| Evening of the visit | Directions or a parking tip, if asked | Service reply | Free for the first 1,000 a month, then $0.0034 |
| Next day | Thank-you with a return-visit offer | Marketing template | $0.025 |
The whole booking costs well under 4 cents in Meta fees, and most of it is the optional offer at the end. Telnyx adds $0.004 per message.
Tips for a great guest experience on WhatsApp
The best restaurant WhatsApp channels feel like talking to the host stand, not a system.
- Ask for opt-in when guests book or order. A checkbox like "Send me updates on WhatsApp" on your booking or ordering page gives you permission to message first, which WhatsApp requires.
- Complete your business profile. Add your opening hours, address, website and menu link so guests find answers before they ask.
- Time reminders well. Send them the afternoon before or a few hours ahead, when guests can still change plans and you can still fill the table.
- Use buttons and quick replies. Confirm, Change and Cancel buttons settle a booking in one tap, and quick replies cover the questions you get every day.
- Show, don't just tell. Send the menu as a PDF, photos of the private dining room, or a location pin with parking tips.
- Make it easy to reach a person. Tell guests when your team is around, and let your AI assistant hand complex requests to staff in the same chat.
- Keep promotions relevant. Guests who feel spammed block your number, which lowers your quality rating with Meta and can limit how many messages you can send.
What WhatsApp costs a restaurant
Meta charges per message you send, based on the message type and the guest's country. Here are the US list rates, effective October 1, 2026:
| Restaurant message | Meta message type | Meta cost (US) |
|---|---|---|
| Booking confirmation, reminder, order update, receipt | Utility template | $0.0034 |
| Promotion, loyalty reward, birthday offer | Marketing template | $0.025 |
| Answering a guest's question, rebooking in chat | Service reply | First 1,000 per number each month free, then $0.0034 |
| A guest calls you on WhatsApp | Customer-initiated call | Free |
On Telnyx, you pay Meta's rate passed through unchanged, plus $0.004 per message and $0.0025 per call minute. There's no subscription, minimum or contract. Rates differ by country; see WhatsApp pricing for every market.
What's free
- Messages guests send you, and calls they make to you.
- The first 1,000 service replies per business phone number each month. Each location with its own number gets its own 1,000.
- Everything you send in the 72 hours after a guest messages you from a click-to-WhatsApp ad or Facebook Page button, templates included (see below).
Since October 1, 2026, two things that used to be free are billed: service replies beyond the first 1,000, and utility templates sent while a guest's 24-hour window is open.
A sample monthly bill
A US restaurant with one WhatsApp number that sends 3,000 confirmations and reminders, 1,000 promotions and 2,000 chat replies a month pays:
| Line | Calculation | Cost |
|---|---|---|
| Confirmations and reminders | 3,000 × $0.0034 | $10.20 |
| Promotions | 1,000 × $0.025 | $25.00 |
| Chat replies | 1,000 free, then 1,000 × $0.0034 | $3.40 |
| Telnyx platform | 6,000 messages × $0.004 | $24.00 |
| Total | $62.60 a month |
Add 300 minutes of guest calls and the bill grows by $0.75: Meta charges nothing and Telnyx charges $0.0025 a minute.
Five ways to keep the bill down
- Keep confirmations and reminders free of offers. A dessert promo in a reminder can turn a $0.0034 utility message into a $0.025 marketing one.
- Use buttons. Confirm, Change and Cancel buttons settle a booking in one tap instead of three or four messages.
- Answer in one complete message. Past the free 1,000, every reply counts, so one clear answer beats three short ones.
- Run promotions through click-to-WhatsApp ads. Chats that start from an ad open a 72-hour window where your messages are free.
- Give each location its own number. Each number gets 1,000 free service replies a month, and guests reach the right team.
WhatsApp calling for restaurants
Some conversations are quicker as a call: planning a birthday dinner, organizing a private event, confirming catering details or sorting out an urgent problem. Guests tap Call in the same WhatsApp chat instead of looking up another number.
With Telnyx, inbound WhatsApp calls can go to your existing phone system, a Voice API application, a TeXML call flow or a Telnyx AI Assistant, with no extra setup. Messaging and calling work together on the same platform, so you can support guests however they prefer to reach you.
Three things make calling useful for restaurants:
- Guest calls are free from Meta. You pay only Telnyx's $0.0025 a minute.
- A call opens the chat. When a guest calls, their 24-hour window opens, so you can follow up with the booking link, menu or deposit details by message right after you hang up.
- You can call guests back. Calls you place need the guest's permission and are billed per minute by Meta, based on the guest's country. They aren't currently available for US and Canadian numbers.
AI assistants for WhatsApp calls and messages
Great guest service shouldn't end when your restaurant closes.
Guests message and call when your team is busy or the restaurant is closed: a table for tomorrow night, a gluten-free question at midnight, a private dining inquiry on a Sunday. A Telnyx AI Assistant can pick those up instead of leaving them for the morning.
On WhatsApp messages, the assistant answers questions about the menu, allergens, opening hours and parking, takes booking requests, and hands anything complex to your team in the same chat.
On WhatsApp calls, it answers inbound calls, captures reservation requests and transfers callers to staff when needed. You can connect your WhatsApp Business number to an AI Assistant in one click. Watch the demo to see how it works.
Instead of sending after-hours guests to voicemail or leaving their messages until morning, you stay responsive outside business hours without adding staff.
What it costs:
- Chat replies: Meta bills AI-written replies as ordinary service messages, so they share your 1,000 free replies a month. There's no extra Meta AI fee. Telnyx bills the AI model by usage: about $0.0003 per reply on a fast model like GLM-5.3 Flash.
- Calls: you pay the call minutes plus the AI's speech and model usage. See Voice AI Agents for current rates.
Because the AI runs on the same infrastructure that carries the call, there's no need to stitch together separate telephony and AI providers, and conversations stay responsive.
Fill tables with click-to-WhatsApp ads
Most restaurants already advertise on Instagram and Facebook. Point those ads at WhatsApp instead of a booking page, and guests start a chat with one tap.
There's a cost benefit too. When a guest messages you from a click-to-WhatsApp ad or a Facebook Page button and you reply within 24 hours, everything you send for the next 72 hours is free from Meta, marketing templates included. That covers the full journey from "Do you have a table Friday?" to the confirmation and the reminder.
Good ads to try: a set menu for a quiet weeknight, a Sunday brunch launch, or "Message us to book your holiday party." The free window only applies to chats started from the WhatsApp app on a phone, not WhatsApp Web or desktop.
WhatsApp vs SMS for restaurants
WhatsApp and SMS each have a job, and they work best together.
SMS is ideal for reliable, time-sensitive notifications that reach virtually any phone. WhatsApp builds on that with richer two-way conversations, where guests can reply, view images, tap buttons and keep the discussion in one thread.
Use WhatsApp when guests need to interact. Reservations, order updates, guest questions, loyalty campaigns and menu sharing all benefit from buttons, images and replies in one thread.
Use SMS when reach is the priority. SMS reaches virtually any phone, so it's the fallback for guests who don't use WhatsApp and for time-critical notices like a same-day closure.
On Telnyx, both run on the same number, so you can send a reminder on WhatsApp and fall back to SMS without a second provider.
Choosing a WhatsApp Business API provider
Every WhatsApp Business API provider connects to Meta and pays the same Meta per-message fees. What differs is the provider's own markup and how well WhatsApp fits the rest of your communications. Our WhatsApp Business API cost guide compares the markups.
One number across every channel
Adding WhatsApp shouldn't mean another provider, another number and another integration. With Telnyx, WhatsApp is another channel on your existing business number. The same number supports:
- WhatsApp messaging
- WhatsApp calls
- SMS
- Regular phone calls
That's one API, one dashboard and one bill for every guest conversation.
Simple pricing
Telnyx passes Meta's fees through unchanged and adds $0.004 per message and $0.0025 per call minute. There's no subscription, no minimum spend and no contract, so a single-location restaurant pays only for what it sends.
Ready for AI
As guest expectations evolve, AI is becoming another way to serve guests rather than a separate product. Because Telnyx combines communications and AI on one platform, you can add an AI assistant to WhatsApp chats and calls without replacing existing workflows or adding vendors. The same infrastructure that handles messaging and voice today supports AI as your plans grow.
Getting started with the WhatsApp Business API
Setup takes six steps.
- Connect your WhatsApp Business Account using Meta Embedded Signup in Mission Control.
- Verify your business phone number. Groups with several locations can use one number per location.
- Create your core templates: a booking confirmation, a reminder and an order update as utility templates, plus one promotion as a marketing template. Submit them for Meta's approval.
- Enable WhatsApp calling and choose where calls go: your phone system, a Voice API app, a TeXML flow or an AI Assistant.
- Tell guests you're on WhatsApp. Add a WhatsApp button to your booking page, website, Instagram profile, receipts and table cards.
- Start messaging and taking WhatsApp calls.
As you grow, the same number keeps supporting WhatsApp, SMS, phone calls and AI from one platform.
