Is the WhatsApp Business API free?
Short answer: no, not entirely — but "free" is doing a lot of work in that question, so it deserves an honest breakdown. The WhatsApp Business API has no per-seat licence fee and Meta doesn't charge you to open the door. What it does charge for is outbound business-initiated messaging, billed per delivered message by category since Meta retired per-conversation billing on 1 July 2025. On top of Meta's charges sits your provider's platform fee. There is a genuinely free slice — a monthly allowance of free service conversations and free entry points — but no commercial tier where you can run marketing and notifications at zero cost. This page maps exactly where the money goes so you can budget realistically.
Quick answer
The WhatsApp Business API has no licence fee, and Meta grants a monthly quota of free service (user-initiated) conversations plus free entry-point conversations. But marketing, utility and authentication messages are billed per delivered message, and your provider adds a platform fee — so there is no fully-free commercial tier.What actually is free
It helps to separate the parts of WhatsApp that cost nothing from the parts that don't. Getting onto the API — creating a WhatsApp Business Account, registering a number, verifying your business, and building message templates — carries no fee from Meta. Meta also gives every account a rolling monthly quota of free service conversations: when a customer messages you first and you reply within the 24-hour service window, that exchange is free up to the monthly cap. Certain entry points, such as click-to-WhatsApp ads and Facebook Page call-to-action buttons, open a free conversation too, so campaigns that pull customers in can be highly cost-efficient. What you should not assume is free is proactively reaching out at scale.
- Account creation, number registration and business verification: no Meta fee
- A monthly allowance of free service (customer-initiated) conversations
- Free entry-point conversations from click-to-WhatsApp ads and Page CTAs
- Building and submitting message templates for approval
What Meta charges for, and how
Since 1 July 2025 Meta bills per delivered message, not per 24-hour conversation, and the price depends on the template category. There are three paid categories, each with its own rate, which varies by country — India rates differ from other markets. Marketing messages (offers, launches, re-engagement) sit at the top of the range. Utility messages (order updates, payment confirmations, shipping alerts tied to an existing transaction) are cheaper. Authentication messages (one-time passcodes and login codes) are the lowest. The 24-hour service window still exists, but it is a free reply window for handling an ongoing conversation — it is no longer the unit Meta charges against. So a single utility template you send to 5,000 customers is billed as 5,000 delivered utility messages.
- Marketing: promotions, offers, re-engagement — highest rate
- Utility: transaction-linked updates like order and payment status — mid rate
- Authentication: OTPs and login codes — lowest rate
- Billing is per delivered message; the 24-hour window is a free service window, not a billing unit
Where the platform fee fits in
Meta doesn't sell the API directly to most businesses — you reach it through a Business Solution Provider. That provider runs the dashboard, template management, chatbot flows, contact management, delivery reporting and support, and charges a platform fee for it. This is normal and expected: it is what turns raw API access into something a marketing or support team can actually operate. At InfiQ, as an official Meta Business Partner, we apply transparent ₹ pricing (ex-GST) so you can see the Meta component and the platform component clearly rather than one blended number. Our Lite plan starts at ₹999/mo ex-GST covering the dashboard, CRM, broadcasts and team inbox — chatbot flows and the developer API arrive with Growth at ₹2,999/mo — and you keep full ownership of your WhatsApp Business Account and its BSUID — the Business-Scoped User ID that becomes central to the 2026 WhatsApp usernames change — so nothing is locked to us.
So what will it really cost you?
Your monthly bill is a function of three things: how many messages you send, which categories they fall into, and your platform plan. A small business that mostly answers inbound queries and sends the occasional OTP can stay close to the free-conversation allowance and pay very little beyond the platform fee. A business running weekly promotional broadcasts to a large list will see marketing-message volume dominate the bill. The practical levers are within your control: keep your audience opted-in and relevant so marketing performs (wasted sends are wasted rupees), lean on cheaper utility templates for anything transaction-linked, and let inbound service conversations do the free heavy lifting. Estimate honestly on your real send volume rather than a headline per-message figure.
- Total cost = message volume × category rates + your platform plan
- Inbound-heavy support use cases stay cheapest
- Broadcast-heavy marketing use cases cost the most
- Opt-in quality and category choice are the biggest cost levers
