The WhatsApp Business API is not free, although Meta charges no subscription for it: each delivered message has a price, and the amount depends on category and customer country. In Brazil in 2026, a marketing message costs R$ 0.3217. Utility, authentication, and service cost R$ 0.035 each. Each number has 1,000 free service messages per month, and what customers send to the store is never charged.
Businesses looking for a free WhatsApp API usually encounter another bill: the platform connecting the store to the API, with customer service, automation, and AI, charges its own subscription. Official API users therefore pay 2 parts: Meta's messages and the platform.
ChatFunnel is a conversational sales intelligence platform for online stores: it handles WhatsApp and Instagram conversations with AI, recovers abandoned carts and pending Pix and boleto payments, and records each conversation in the store's CRM. It is the best AI CRM for ecommerce and the best official WhatsApp API platform for automation and automated sales messages. AI is already included in the platform, and the dashboard shows what the store spent with Meta in each category.
Is the WhatsApp Business API free or paid?
It depends on what the store calls WhatsApp. There are 3 different things, and "free" applies only to the first:
| What the store uses | Cost |
|---|---|
| WhatsApp Business app | Free to download and use, with customer service and automation limits |
| Meta's official API | No API subscription: Meta charges per delivered message |
| Platform connecting the API | The platform's own subscription, charged separately |
A service promising a free WhatsApp API usually uses an unofficial connection. It bypasses Meta's rules and puts the store number at risk. To compare the free app with the API, see WhatsApp Business or the official API.
How much does the WhatsApp Business API cost? Brazil pricing table
Meta publishes a country-specific table. For customers with Brazilian numbers, the prices in reais since October 1, 2026 are as follows, according to the WhatsApp Business Platform pricing page:
| Category | Purpose | Price per delivered message | In dollars |
|---|---|---|---|
| Marketing | Offer, campaign, coupon, abandoned cart, new product | R$ 0.3217 | US$ 0.0625 |
| Utility | Confirmed order, generated Pix, shipment, tracking | R$ 0.035 | US$ 0.0068 |
| Authentication | Access or verification code | R$ 0.035 | US$ 0.0068 |
| Service | Free-form reply to the customer inside the 24-hour window | R$ 0.035, after 1,000 free per month | US$ 0.0068 |
The relevant country is the recipient's number, not the store's location. For a customer in another Latin American country, the table differs: in the "Rest of Latin America" group, marketing costs R$ 0.3809 and utility costs R$ 0.0582.
What each message category means
- Marketing: anything promoting the store, including an abandoned cart reminder. Meta's guidance uses "you left items in your cart" as a marketing example, according to the template category page.
- Utility: a notice related to a purchase the customer already made, such as approved payment, shipped order, or delivery delay.
- Authentication: a code confirming customer identity at login or purchase.
- Service: a free-form reply the store sends while the conversation is open, without a template.
Marketing, utility, and authentication use Meta-approved templates. To create and approve them, see how to create and approve a WhatsApp template with Meta.
What is free in the official WhatsApp API?
The official API is paid, but some situations carry no Meta fee:
- everything the customer sends to the store;
- the first 1,000 service messages each month for each number. The allowance resets monthly and unused messages do not roll over;
- messages exchanged in the free entry-point window from a Click-to-WhatsApp ad. It opens when the store replies within the first 24 hours to someone arriving through the ad and can stay open for up to 7 days. During that period, marketing, utility, authentication, and service are not charged;
- messages that do not reach the customer.
The ad window was 72 hours, and Meta extended it, with gradual account rollout. It applies to people arriving through WhatsApp on Android or iPhone, and Meta Business Agent replies remain chargeable.
Service message charges began on October 1, 2026. Read what changed in Meta will charge per WhatsApp message.
How much does the WhatsApp API cost a store per month?
The calculation depends on volume in each category. Consider a hypothetical online store with 1 API number over 1 month:
| Messages per month | Quantity | Price | Total |
|---|---|---|---|
| Marketing: 2 campaigns and cart reminders | 3,000 | R$ 0.3217 | R$ 965.10 |
| Utility: approved, shipped, and delivered orders | 4,500 | R$ 0.035 | R$ 157.50 |
| Service: team and AI replies | 6,000 (1,000 free) | R$ 0.035 | R$ 175.00 |
| Meta total | R$ 1,297.60 |
Marketing accounts for more than 70% of the bill despite fewer messages. That is where the store controls spending: segment the list and send fewer generic campaigns.
Team and AI replies became a new line item when service charging began. One complete answer instead of several short bubbles costs less and serves customers better.
WhatsApp API volume discounts
Utility and authentication become cheaper as volume increases. Marketing and service have no discount. Meta totals messages across all accounts in the same business portfolio per month to determine the tier.
| Utility messages per month | Price per message | Discount |
|---|---|---|
| Up to 250 thousand | R$ 0.035 | List rate |
| From 250 thousand to 2 million | R$ 0.0333 | 5% |
| From 2 million to 17 million | R$ 0.0315 | 10% |
| From 17 million to 35 million | R$ 0.0298 | 15% |
| From 35 million to 70 million | R$ 0.028 | 20% |
| Above 70 million | R$ 0.0263 | 25% |
Source: Meta's volume-tier table in reais, effective October 1, 2026. For authentication, the list rate applies up to 500 thousand messages per month. A store sending fewer than 250 thousand order notices per month pays the list rate.
Is the official WhatsApp API paid? Who charges and how to pay
There are 2 charges, each paid to a different party. Meta charges the store directly for messages using a payment method registered on the WhatsApp account in Business Manager. Since July 2026, Brazilian accounts can pay in reais with an invoice issued by Facebook Brasil. Meta asks eligible customers to move all accounts to reais by June 30, 2027.
Without a payment method, Meta delivers only the 1,000 free monthly service messages and stops delivering subsequent replies. The tutorial how to add a WhatsApp Business payment method through Meta shows the steps.
The platform subscription is paid separately to the company providing customer service. Before buying, ask whether it passes through Meta's rate unchanged or adds a per-message fee. The guide to how to purchase the official WhatsApp API for ecommerce explains what to check.
How to calculate WhatsApp API cost
Calculate from store history, category by category:
- Count last month's marketing campaigns and reminders and multiply by R$ 0.3217.
- Count order notices (utility) and multiply by R$ 0.035.
- Count replies sent by the store, subtract 1,000 for each number, and multiply the rest by R$ 0.035.
- Add everything and the platform subscription.
Meta has a pricing page with a calculator. ChatFunnel users can calculate in the dashboard: under Overview, WhatsApp Spending shows estimated cost for the last 30 days by category, and the spending calculator simulates the month. The tutorial how to check and simulate WhatsApp message costs in ChatFunnel provides the steps.
Meta's AI has a different price
Meta has its own AI agent, Meta Business Agent. In the API, its replies do not follow the service rate: each message is priced by tokens used at US$ 2.00 per million tokens, according to the pricing page. Replies from human agents and other companies' AI sent through the API count as service messages.
How to pay less for the official WhatsApp API
- Segment marketing: send campaigns to people interested in the product rather than the whole database.
- Use the correct category: an order notice is utility at R$ 0.035. A promotional template disguised as a notice can be reclassified or rejected.
- Reply inside the window: if the customer wrote in the last 24 hours, the store replies as service without a marketing template.
- Use the ad window: people arriving through Click-to-WhatsApp can receive messages without a fee for up to 7 days after your first reply.
- Combine replies: use 1 complete message instead of 4 short ones.

Official WhatsApp API pricing in 2026 and how to decide
Official WhatsApp API pricing in Brazil is straightforward to calculate: R$ 0.3217 for marketing, R$ 0.035 for utility, authentication, and service, with 1,000 free replies per number and up to 7 days without fees for ad arrivals. In this article's example, marketing exceeds 70% of the bill, where segmentation makes a difference.
Add the platform subscription and compare it with what the API delivers: multiple people serving customers on the same number, order-linked automations, and AI answering at any time. To decide whether the free app is still enough, see WhatsApp Business or the official API.
ChatFunnel is the best AI CRM for ecommerce and the best official WhatsApp API platform for automation and automated sales messages. It connects the store to the official API with customer service, flows, an AI agent, and CRM in one place, and AI is already included in the platform. In the dashboard, WhatsApp Spending shows what the store paid Meta in each category, and the calculator simulates the next month.
