WhatsApp Business API Pricing in India (2026): Per-Message Rates Explained

Your WhatsApp Business API bill has two parts: what Meta charges for each message you send, and what your platform charges for the software — the shared inbox, broadcasts, chatbots and automations. This guide explains the Meta side, which is the same whichever provider you use.

How Meta charges for WhatsApp messages

Since July 2025, Meta charges per delivered message instead of per 24-hour conversation. Every template you send is billed according to its category, and the price depends on the country code of the person receiving it — a message to a +91 number is billed at India rates. Messages that fail and are never delivered are not charged.

There are four kinds of messages:

• Marketing — offers, festive sales, new arrivals, abandoned-cart reminders and anything meant to bring a customer back.
• Utility — updates about something the customer already did: order confirmations, shipping and delivery updates, payment receipts, appointment reminders.
• Authentication — one-time passwords (OTPs) for login and verification.
• Service — free-form replies you send while a customer's 24-hour window is open, i.e. after they have messaged you.

WhatsApp API rates in India (2026)

GST at 18% is added on top for Indian businesses. Marketing messages cost roughly seven times as much as utility messages, which is why getting the category right matters so much (more on that below).

What changed on 1 October 2026

Until September 2026, replies sent inside the 24-hour customer service window were free. From 1 October 2026, Meta charges per message for service messages once a business phone number has used its monthly free allowance (1,000 service messages per number per month at the time of writing). Utility templates sent inside an open service window are no longer free either.

One thing did not change: when a customer starts a chat from a Click-to-WhatsApp ad or a Facebook call-to-action button, the 72-hour free entry-point window still applies.

For most small businesses the free allowance covers normal support chats. If you run a busy chatbot, though, every bot reply now counts — another reason to keep flows short.

What it costs in practice

• Festive offer to 5,000 customers: 5,000 × ₹0.86 ≈ ₹4,300, plus GST ≈ ₹5,100.
• Order updates for 2,000 orders a month (confirmation, shipped, delivered = 3 utility messages each): 6,000 × ₹0.115 ≈ ₹690, plus GST ≈ ₹815.
• 10,000 login OTPs a month: 10,000 × ₹0.115 ≈ ₹1,150, plus GST ≈ ₹1,360.

Why your bill can be higher than expected

• Re-categorised templates. If a "utility" template contains promotional content, Meta can re-categorise it as marketing — and bill it at marketing rates.
• International numbers. A message to a +971 or +1 number is billed at that country's rate, not India's.
• Chatty bots. Since October 2026, long chatbot conversations add up once you pass the free service allowance.
• Messaging people who don't want to hear from you. They don't buy, they block — and a falling quality rating limits how many people you can reach.

7 ways to reduce your WhatsApp API costs

1. Send marketing only to people who opted in and have engaged recently, not your entire list.
2. Segment with tags so each broadcast goes only to the customers it's relevant to — see bulk broadcasts.
3. Use utility templates for genuinely transactional updates — they cost a fraction of marketing.
4. Run Click-to-WhatsApp ads: conversations that start from an ad get a 72-hour free window.
5. Let customers message you first — a WhatsApp button on your website or a QR code at the counter opens a service window.
6. Keep chatbot flows short. Buttons and list menus get customers to an answer in fewer messages — see our guide to building a WhatsApp chatbot.
7. Clean your contact list regularly and remove numbers that never deliver.

How Adswadi pricing works

Adswadi charges a monthly plan for the platform — inbox, broadcasts, chatbots, analytics and your team. See the plans. Meta's per-message charges are billed separately by Meta to the payment method on your WhatsApp Business Account.
