WhatsApp Session Message Pricing: New Meta Rules & 13 Paise Rate
Meta has changed how WhatsApp session messages are billed. The replies your business sends inside the 24-hour customer window, chatbot answers, live chat responses, session API messages, were free under the old conversation rules. Under Meta’s new pricing they are charged like other message categories. That sounds like bad news, but here is the part that matters: pricing still depends entirely on your provider. On Fast2SMS the platform itself stays completely free, with no setup cost and no monthly cost, and a session message costs just 13 paise. This guide explains the new rules, the exact rates, and how to keep your chatbot economics healthy.
What is a session message?
When a customer messages your WhatsApp Business number, a 24-hour session window opens. Inside that window your business can reply free-form, without pre-approved templates: text, images, documents, audio, video, location, stickers and reactions. Everything your chatbot answers, every reply your team sends from Live Chat, and every call to the session message API is a session message.
What Meta changed
| Old rules | New rules | |
|---|---|---|
| Session / service replies (24-hour window) | Free service conversations | Charged per session message |
| Utility & authentication templates | Charged per conversation | Charged per message |
| Marketing templates | Charged per conversation | Charged per message |
| What decides your final rate | Your provider | Still your provider |
The direction is clear: WhatsApp moved from conversation-based to per-message billing, and the free ride on service replies ended. What did not change: providers set their own margins and platform fees on top, and that is where the real cost difference lives.

What 13 paise means in real numbers
- A support chatbot that answers 1,000 customer queries with one reply each: ₹130. No platform fee on top.
- A busy store doing 5,000 session replies a month (bot plus live agents): ₹650 total.
- A quiet month with 50 replies: ₹6.50. You pay only what you use, and an unused account costs exactly nothing.
The monthly-fee trap at other vendors
Most WhatsApp API vendors in India price the same Meta infrastructure very differently: a monthly platform or CRM subscription, often per-agent seats for the inbox, sometimes chatbot add-on charges, and then per-message rates with markup on top. Under the new session pricing that stack gets heavier, because you now pay their monthly fee and per session message.
| Typical vendor stack | Fast2SMS | |
|---|---|---|
| Monthly platform / CRM fee | Recurring, paid even in slow months | ₹0 |
| Chatbot | Often a paid add-on or higher plan | Free builder, pay 13p per bot reply |
| Live Chat inbox | Per-agent seat pricing | Free |
| Session message | Charged, plus everything above | ₹0.13, and nothing above |
| You stop sending for a month | You still pay the subscription | You pay ₹0 |

The free tools the 13p rate powers
Drag-and-drop chatbot builder: keyword triggers, buttons, lists, media replies, conditions and an API-request block that can query your own systems mid-conversation. The builder is free; you pay only the 13p when the bot actually replies to someone.
Live Chat inbox: a WhatsApp-Web-style team inbox with contact notes and tags, no per-agent seat fees. Agents reply inside the session window at the same 13p per message.
Developers: the same rate applies to the chatbot API loop: catch incoming messages with a webhook, reply with one POST to the session message API, 13p per reply. Templates for starting conversations go through the WhatsApp message API at the utility/auth or marketing rate.
