What changed in WhatsApp Business API pricing

Since July 1, 2025, Meta has charged per delivered message rather than per conversation ². Replies inside the customer service window were free from November 1, 2024 to September 30, 2026 ³. Utility templates sent while that window is open, free since July 1, 2025, are billed again since October 1, 2026 ⁴.

The charge covers every free-form reply in the window, whether a person or a chatbot writes it ⁵, and replies from third-party AI count as service messages too ⁶. It applies only to the API, usually connected to a CRM, an automation platform or a contact center: messages sent directly from the WhatsApp Business app stay free ⁷.

Meta bills by the recipient's country calling code, not by where your business is based ², and US and Canadian numbers share Meta's North America list rates, read from the rate card effective October 1, 2026 ⁸. One US-specific catch changes the table: WhatsApp does not currently deliver marketing templates to US phone numbers ⁹. Per delivered message, the rates are:

Service messages have no volume discount: tiers apply only to utility and authentication messages ¹¹, and Meta counts those across all the numbers in your business portfolio ¹². Whatever your volume, every reply past the free allowance costs the same.

The impact depends almost entirely on how many replies each number sends per month. Every phone number has 1,000 free service messages a month, and only the replies past that line are billed, at the utility rate ¹³. Below the line the change costs nothing; above it, the bill grows in step with volume, because service messages have no tiers ¹¹.

So the math for one number is short: replies sent in the month, minus the free allowance, times the rate for your customers' country, which is $0.0034 for US numbers ¹⁰. Run it for each number you operate.

The free allowance is per phone number, not per company ¹³, and unused messages don't roll over ¹⁴. Concentrating all your support on a single number wastes the allowance you'd get on the others.

Long conversations now drive the bill. Meta counts messages, not conversations ¹⁵, so every back-and-forth inside the window adds a billable reply once the allowance runs out.

Meta Business Agent, Meta's own AI for answering on WhatsApp, has been billed per token since August 1, 2026 ¹⁶. Meta charges one global rate of $2.00 per 1 million tokens, and a message typically consumes 20,000 to 25,000 tokens, which comes to about 4 to 5 US cents per message ¹⁷. Replies from people and from third-party AI are still billed as ordinary service messages ⁶.

On top of Meta's fees, the platform you use to reach the API bills its own plan ¹⁸. The choice between Meta's agent and a third-party AI therefore comes down to total cost per conversation, platform included.

Messages your customers send you remain free ¹⁹, as do the first 1,000 service messages per number each month ²⁰. When a customer messages you from a Click to WhatsApp ad and you reply, Meta opens a free entry point window that, according to its documentation, can remain open for up to 7 days ²¹. Inside it, Meta Business Agent messages are still charged ²².

That gives Click to WhatsApp ads new weight. Besides the lead, they now bring days of conversation with no messaging fee, which changes the math for anyone comparing this format with other acquisition channels.

Before your next invoice, pull three figures from last month for each WhatsApp number: replies sent inside the window, utility templates sent while it was open, and marketing templates sent to customers outside the US. Subtract the 1,000 free replies per number ²⁰, multiply the rest by the rate for each customer's country (the table above covers US numbers) and add it up.

Then look at how support is spread across your numbers, the average number of messages per conversation and where the AI that answers comes from: those are the three places where the bill changes. Meta's official rate cards are on the pricing page of its developer documentation ²³.
