What is changing in WhatsApp Business API pricing from October 1, 2026? +
From 1 October 2026, Meta will start charging for two message types that are free today — service messages (free-form replies inside an open 24-hour customer service window) and Utility template messages sent inside that same window. Marketing, Authentication, and out-of-window Utility rates are not changing.
How much will service messages cost after October 1, 2026? +
Meta has indicated service messages will be billed at the same rate as a Utility or Authentication message to that country — in India, that is ₹0.1150 per message plus 18% GST — though Meta's confirmed country-level service-message rate card is expected closer to the effective date.
Will WhatsApp OTP and authentication message costs increase? +
No. Authentication template pricing (₹0.1150 per message plus 18% GST in India) is unaffected by this update — only service messages and in-window Utility templates are becoming newly chargeable.
Does the 72-hour free entry point window still stay free? +
Yes. Messages sent within 72 hours of a customer tapping a Click-to-WhatsApp ad or Facebook Page button remain free for message delivery — that window is untouched by the October 2026 change.
How can a business reduce the cost impact of this change? +
Audit how many free-form replies and in-window Utility templates you send monthly, consolidate multi-step replies into a single message or a WhatsApp Flow, and route high-volume, template-safe updates through SMS or RCS with automatic failover instead of the WhatsApp API where it makes sense.
Who is affected the most by the October 2026 WhatsApp pricing change? +
Businesses that lean on WhatsApp for live customer support, chatbot conversations, or order-status updates sent while a customer service window is open — e-commerce, logistics, and support-heavy businesses will feel it more than businesses that mostly send Marketing or Authentication templates.
