WhatsApp API Pricing 2026: Twilio, 360dialog, MessageBird

As of October 2026, what you pay for a WhatsApp API depends on which kind you use. On the official WhatsApp Business Platform, Meta charges for each delivered template message, at a rate set by the message category and the recipient's country, and since October 1, 2026 it also charges for free-form replies beyond 1,000 per number per month. Providers such as Twilio, 360dialog, WATI and Bird (formerly MessageBird) add their own fee per message, per number or per seat. Chatmaid Developers works on your own WhatsApp number instead: $7.99 a month flat, no per-message fees, and a free sandbox.

This guide lists each provider's published prices, works out the cost of 1,000, 10,000 and 50,000 messages a month, and covers the tradeoffs the price lists leave out. Providers change their prices, so check the linked pages before you set a budget.

How does WhatsApp API pricing work in 2026?

Meta replaced conversation-based pricing with per-message pricing on July 1, 2025, according to its pricing documentation. If a comparison you are reading prices "24-hour conversations", it is out of date.

Meta charges only for messages that are delivered, and never for messages users send to you. Meta sorts what you send into four categories: three kinds of template (pre-approved message formats) and free-form service messages. Each has its own rate in each market:

The US rates are the Meta fees listed on Bird's WhatsApp pricing page, checked October 22, 2026. Other countries differ, so look them up on Meta's rate card.

Since July 1, 2026, Meta also has a fifth category, Meta Business Agent. It covers non-template messages written by Meta's own business AI and is billed per token, at $2.00 per million tokens, which Meta estimates at about 4 to 5 US cents a message. It only applies if you use that agent, so the rest of this guide leaves it out.

Service messages are only allowed inside a customer service window. That window opens when a user messages or calls you, lasts 24 hours, and resets each time they write again. Once it closes, you can only send pre-approved templates (Meta: sending messages).

There is one more free period. When someone messages you from a Click to WhatsApp ad in the Android or iOS app and you reply inside the customer service window, that reply is free and opens a free entry point window of up to 7 days. During it, Meta charges nothing for marketing, utility, authentication or service messages. Only Meta Business Agent messages are still billed.

A few more rules shape the bill:

• Rates depend on the message category and on the country calling code of the recipient's number.
• Utility and authentication messages have volume tiers: the more you send in a market in a month, the lower the rate.
• Meta changes rates only on the first day of a quarter, with at least a month's notice for rate card updates.
• Meta's documentation says WhatsApp does not currently deliver marketing templates to users with United States phone numbers.

Whatever a provider charges comes on top of these Meta fees.

What changed in WhatsApp API pricing on October 1, 2026?

Two things that used to be free are now billed, according to the same Meta pricing page:

1. Service messages. Free-form replies inside a customer service window were free from November 2024. Since October 1, 2026, each business phone number gets 1,000 free service messages a month, and Meta charges from the 1,001st. Unused free messages do not roll over.
2. Utility templates inside the window. Utility templates sent while a customer service window is open had been free since July 1, 2025. Since October 1, 2026, they are charged like any other utility template.

Meta also updated 40 rates on the rate card that day. For a support team that answers thousands of customer chats a month, this is the change that moves the bill most: replies that cost nothing in September now have a price after the first 1,000 per number. If a provider's calculator still shows utility messages inside the window as free, it predates the change.

Official API or personal-number API: what is the difference?

There are two kinds of WhatsApp API, and they are priced in completely different ways.

The official WhatsApp Business Platform. You use Meta's Cloud API directly, or through a provider built on it, such as Twilio, 360dialog, WATI or Bird. Your number belongs to a WhatsApp Business Account under a Meta business portfolio. You pay Meta's per-message fees plus any provider fees, and anything you send outside a customer service window must be an approved template.

A personal-number API (Chatmaid). Chatmaid connects a WhatsApp number you already have as a linked device, the same way WhatsApp Web does. You scan a QR code with the WhatsApp app, and your phone stays logged in. There are no templates, no 24-hour window and no Meta fees, so the price is a flat subscription.

The tradeoff is that this is not Meta's official platform. Chatmaid is independent and not affiliated with Meta, you get no verified business account, and a number that behaves like spam can be restricted by WhatsApp. For the longer version, read WhatsApp API without Meta Business verification.

What does each provider charge?

All prices below are from the providers' own pages as of October 2026.

Chatmaid Developers

Model: flat subscription, no per-message fees.

Extra connected numbers are a paid add-on; the current price is on the pricing page.

Messages can carry text, images, documents, audio and video. Signed webhooks report status changes such as message.delivered and message.read, and incoming messages arrive as message.received (see the webhook guide). There is a JavaScript SDK (@chatmaid/sdk) and an MCP server (@chatmaid/mcp) for AI agents. Interactive buttons and list messages are planned, not available yet.

In the sandbox, add a test number in the dashboard first. Sandbox numbers connect without a QR scan. After that, a first send is one request:

curl -X POST https://developers-api.chatmaid.net/v1/messages/send \
  -H "Authorization: Bearer sk_test_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "fromPhoneId": "+15551234567",
    "to": "+15557654321",
    "content": "Your order has shipped."
  }'

Replace sk_test_xxx with your sandbox key and fromPhoneId with your sandbox number (or its ID from GET /v1/phone-numbers). With an sk_test_ key the send is simulated: the response comes back as sent, a message.sent webhook fires, and nothing reaches WhatsApp. To go live, subscribe, add your real number and scan the QR code, then send from it with an sk_live_ key. The host and endpoint stay the same. The getting started guide has the full flow.

Best for: developers, startups, internal tools and AI agents that need a predictable bill and want to go live the same day.

Weak spots: not Meta's official platform, no verified business account, and it suits normal human-volume sending, not bulk messages to people who do not expect them.

Meta Cloud API (direct)

Model: Meta's per-message fees only.

If you connect to the Cloud API yourself, no provider sits in the middle, so for messaging you pay Meta's rate card and nothing else. You also do the work a provider would: set up the business portfolio and WhatsApp Business Account, get templates approved, track customer service windows, and build your own inbox or tooling.

Best for: engineering teams that want official access at the lowest per-message cost and can build the rest themselves.

Twilio

Model: a Twilio fee on every message, plus Meta's fees passed through.

Source: Twilio's WhatsApp pricing page, as of October 2026. The inbound part matters. Twilio's $0.005 also applies to messages your customers send you, which Meta never charges for. A support chat with 10 messages each way costs $0.10 in Twilio fees alone. Twilio also sells an optional engagement add-on (link shortening, click tracking, message scheduling) at $0.015 per message, with the first 1,000 each month free.

Best for: teams that already run SMS or voice on Twilio and want WhatsApp on the same account. For a direct comparison, see Chatmaid vs Twilio.

360dialog

Model: a fixed monthly fee per number, plus Meta's fees.

Meta's messaging fees are added on top of every plan, and 360dialog says it adds no markup to them. Prices are in euros on 360dialog's pricing page as of October 2026, which also lists separate plans for partners that resell WhatsApp access.

Best for: steady, high-volume official messaging, where a fixed fee per number costs less than a markup on every message.

WATI

Model: a team inbox plan, plus message charges.

WATI is a shared team inbox built on the official API rather than a raw API. As of October 2026, WATI's pricing page lists Growth at $59 a month and Pro at $119 a month, both billed annually, and Business at a custom price. Growth includes 3 users with no option to add more. Pro and Business include 5, with extra users at $39 a month on Pro and $89 a month on Business. Messages are charged on top at WATI's own rate card, which varies by marketing, utility and authentication and by the recipient's country. There is a 7-day free trial.

Best for: support and sales teams that want an inbox to work in, not an API to build on.

Bird (formerly MessageBird)

Model: a Bird fee on outbound messages, plus Meta's fees, with optional prepaid plans.

Source: Bird's WhatsApp pricing, as of October 2026. The figures above are Bird's US rates; check the page for other countries.

Best for: businesses that already use Bird for email or SMS and want WhatsApp in the same place.

What does 1,000, 10,000 or 50,000 messages a month cost?

The table assumes utility templates (order updates, for example) sent to US numbers from one sender number, with every message delivered. Since October 1, 2026, Meta charges for utility templates whether or not a customer service window is open, so the window does not change the result. It uses the $0.0034 Meta rate that Bird lists for US utility messages in October 2026. Meta's volume tiers lower the utility rate as monthly volume grows, so the larger figures for the official options are upper bounds.

WATI is left out: its cost is a plan fee plus its own per-message rate card, so it does not reduce to Meta's rate plus a fee.

Four things the table does not show on its own:

1. At low volume, the official route is cheap in fees. Sending 1,000 US utility messages through Meta directly costs $3.40, less than Chatmaid's $7.99. What you pay for instead is setup time: a business portfolio, approved templates and code that tracks the 24-hour window.
2. Replies change the math. Twilio charges $0.005 for each inbound message, so if a quarter of 10,000 recipients reply once, that adds 2,500 × $0.005 = $12.50. Answering them is free on Meta's side only up to 1,000 service messages per number per month; after that, Bird lists Meta's US service rate at $0.0034 per message. Chatmaid meters neither.
3. Country matters for every official option. The table uses one US rate. If your customers are elsewhere, or you send marketing templates, look up those rates on Meta's rate card. Chatmaid's price has no country component.
4. At 50,000 messages, price is not the deciding factor. Chatmaid's bill stays at $7.99, but 50,000 messages a month from one personal number to people who do not have you saved is the pattern that gets WhatsApp numbers restricted. Chatmaid's own guidance is to stay within normal human-volume sending and to message only people who expect to hear from you. If that volume is opt-in notifications to a large customer base, the official platform is built for it.

What costs do not show up on the price list?

On the official platform:

• Template review. Messages you start outside a customer service window need an approved template, and Meta says an approval decision can take up to 24 hours. Plan your templates before launch day.
• Messaging limits. A new business portfolio can reach 250 unique users per moving 24-hour period outside customer service windows (Meta: messaging limits). Going to 2,000 takes business verification or 2,000 delivered high-quality template messages to unique users within 30 days.
• Window tracking. Your code has to know whether a customer's window is open before it sends free-form text, and fall back to a template when it is not.
• Rate changes. Meta can change rates on the first day of any quarter, so a budget built in one quarter can be wrong in the next. October 1, 2026 is a recent example.
• Seats and numbers. WATI charges for users beyond the plan's included seats, and 360dialog charges per number.

On Chatmaid:

• No official status. You do not get a WhatsApp Business Account, Meta verification or Meta's support path. Chatmaid is independent, and you are responsible for following WhatsApp's terms of service.
• Number health is your job. Restrictions happen when an account behaves like spam, for example unsolicited bulk messages or many user reports. If a number is blocked, you can scan a new one from the dashboard and keep your API keys, webhooks and history.
• Feature gaps. Buttons and list messages are not available yet.

Which WhatsApp API should you choose?

Choose Chatmaid if:

• You want to send from a number people already know, today, without business verification or templates
• You want one flat price whatever your volume or your recipients' countries
• You are building internal alerts, AI agents, prototypes or customer conversations at normal human volume
• You do not need an official business account

Choose Meta's Cloud API directly if:

• You need official access at the lowest per-message cost
• You have engineers to handle templates, windows and tooling

Choose a provider (Twilio, 360dialog, WATI or Bird) if:

• Your legal or compliance team requires Meta's official platform
• You send large volumes of opt-in notifications to customers who do not otherwise write to you
• You want a provider's support, console or team inbox on top of the official API

You can also split the work: Chatmaid for conversations, internal alerts and agent workflows, and an official provider for high-volume transactional notifications where templates are acceptable.

To try Chatmaid, start free in the sandbox from the Developers page: create an account, then an sk_test_ key in the dashboard. All plans are on the pricing page.

Frequently asked questions

How much does the WhatsApp Business API cost in 2026?

Meta charges per delivered template message, with rates by category and recipient country, and per service message after 1,000 free per number each month. Providers add their own fees: Twilio $0.005 per message, 360dialog from €49 per number per month, Bird $0.005 per outbound US message. Chatmaid Developers, which is not the official API, costs $7.99 a month flat.

Are WhatsApp service messages still free?

Only up to a point. Since October 1, 2026, each business phone number gets 1,000 free service messages a month, and Meta charges for each one after that. Utility templates sent inside a customer service window, free from July 2025, are now charged too.

Does Twilio charge for incoming WhatsApp messages?

Yes. Twilio's $0.005 fee applies to inbound and outbound WhatsApp messages. Meta itself never charges for messages users send to you, so the inbound cost is Twilio's alone.

Is 360dialog cheaper than Twilio?

It depends on volume. 360dialog's Regular plan is a fixed €49 per number per month, while Twilio charges $0.005 per message with no monthly fee. Twilio's fees reach $50 at 10,000 messages, so around that volume, depending on the exchange rate, the fixed fee starts to come out ahead. Both add Meta's fees on top.

Is Twilio more expensive than Meta's Cloud API?

Per message, yes. Twilio passes Meta's fees through and adds $0.005 for every message, inbound or outbound, so 10,000 US utility templates cost about $84 through Twilio and $34 direct at October 2026 rates. Going direct, you set up the business portfolio yourself and build the template handling, window tracking and tooling that Twilio's console would otherwise give you.

Is there a free WhatsApp API?

Not for production sending. Meta gives each business number 1,000 free service messages a month but charges for every delivered template, and providers add their own fees. Chatmaid's sandbox is free with no card and no expiry: sk_test_ keys simulate sends and fire the message.sent webhook without contacting WhatsApp. Delivery, read and incoming-message events only happen on a live number.
