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<\/strong>. This guide explains the new rules, the exact rates, and how to keep your chatbot economics healthy.<\/p>\n

What is a session message?<\/h2>\n

When a customer messages your WhatsApp Business number, a 24-hour session window<\/strong> 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<\/a> answers, every reply your team sends from Live Chat, and every call to the session message API<\/a> is a session message.<\/p>\n

\n \"Chatbot
Every bot or agent reply inside the 24-hour window is a session message, and Meta now bills them.<\/figcaption><\/figure>\n

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.<\/p>\n
