WhatsApp Business API pricing in India (2026): what you actually pay

WhatsApp API pricing confuses almost everyone, partly because it changed twice in two years and partly because providers bundle it differently. Here is how it works in 2026, in plain words.

Rates change. Figures below were checked in November 2026 against Meta’s pricing documentation and published Indian rate summaries. Always confirm on Meta’s official pricing page before planning a budget.

The model: you pay per delivered template message

Until mid-2025, Meta charged per 24-hour “conversation”. Since 1 July 2025, it charges per delivered message, based on two things:

1. The message category (marketing, utility, authentication or service).
2. The recipient’s country code (for Indian numbers, the India rate applies).

Messages that customers send to you are always free.

The four message categories

Category	What it is	Example	Approx. India rate (2026, before GST)
Marketing	Promotions, offers, re-engagement	“Our Diwali offer ends Sunday”	about ₹0.86 per message
Utility	Updates about something the customer asked for	Order update, appointment reminder	about ₹0.12 per message
Authentication	One-time passwords	“Your OTP is 482913”	about ₹0.12 per message
Service	Free-form replies inside the 24-hour window	Answering a customer’s question	1,000 free per number per month

Meta raised India’s marketing rate by roughly 10% on 1 January 2026. Utility and authentication rates go down with volume tiers; marketing has no volume discount.

What is free

• All incoming messages from customers.
• Service replies: each business number gets 1,000 free service messages a month within the 24-hour customer service window. From 1 October 2026, service messages beyond that free tier are billable.
• Free entry point: when someone messages you from a click-to-WhatsApp ad, all your replies are free for 7 days (except Meta’s own AI agent messages). See click-to-WhatsApp ads.

Note that from 1 October 2026, utility templates sent inside an open service window are also charged; before that they were free.

The 24-hour window, explained

When a customer messages you, a 24-hour customer service window opens. Inside it you can send free-form replies (service messages). Each new message from the customer resets the clock.

Outside the window, you can only send pre-approved templates, and those are charged by category. That is why fast replies matter twice: they win the lead and they keep the conversation in the cheaper window.

A worked example

A clinic gets 600 new enquiries a month on WhatsApp.

• Replying to all 600 inside the 24-hour window: service messages. Even at a few replies each, a small clinic is likely to stay near or under the 1,000 free monthly tier. If they came from click-to-WhatsApp ads, replies are free for 7 days anyway.
• 400 appointment reminders as utility templates: 400 × ₹0.12 ≈ ₹48.
• One promotional message to 1,000 past patients as marketing: 1,000 × ₹0.86 ≈ ₹860.

Add 18% GST and the clinic’s Meta bill for the month is roughly ₹1,000, most of it from the single marketing blast. Your CRM or provider fee comes on top.

Provider fees: the other half of the bill

You cannot use the API directly without technical work, so most businesses use a provider or a CRM. Providers charge in different ways:

• A monthly platform fee with Meta charges passed through at cost.
• A markup per message on top of Meta’s rate.
• Bundles of messages inside a plan.

When comparing, ask three questions: What is your monthly fee? Do you add anything to Meta’s per-message rate? Who pays Meta, and in which currency?

How to keep WhatsApp API costs low

1. Reply fast. Most sales conversations can happen inside the free service window.
2. Use click-to-WhatsApp ads for acquisition: 7 days of free replies.
3. Classify templates honestly. Reminders about a booking are utility; offers are marketing. Meta re-categorises misused templates.
4. Send marketing to people who want it. Blasting cold lists costs money and gets numbers flagged.
5. Set a monthly budget cap in your software if it supports one.

Do you even need the API?

If one person handles a few chats a day, the free WhatsApp Business app may be enough. If a team needs to share one number, add AI replies or automate follow-ups, you need the API. Compare both in WhatsApp Business app vs API.

How OakDeal handles this

OakDeal connects your number through Meta’s official WhatsApp Business Platform. Its AI replies inside the customer service window, which is where most selling happens, and paid templates are off unless you switch them on, so there are no surprise Meta charges. Workspaces can also set a monthly AI budget that the assistant will not exceed.
