How WhatsApp API Pricing Actually Works

WhatsApp API pricing confuses people because it isn't one number — it's two separate charges from two separate parties, and most confusion disappears once you see them apart.

Layer One: Meta's Conversation Charges

Meta charges per conversation (a 24-hour message window), based on category:

• Marketing — promotional messages and campaigns, usually the highest rate.
• Utility — order confirmations, shipping updates, appointment reminders.
• Authentication — OTPs and login codes.
• Service — replies within a customer-initiated 24-hour session are typically free of a per-conversation charge.

These rates are set by Meta, vary by country, and change from time to time — they aren't something any provider controls.

Layer Two: The Platform Subscription

This is what you pay a provider like WaSarthi for the actual software: the shared inbox, broadcasting tools, automation builder, AI agent, CRM and analytics. This is a flat, predictable fee — usually monthly — separate from how many messages you send.

Why the Split Matters

When a provider advertises "starting at ₹X," check whether that's the platform fee, an estimate that includes typical Meta charges, or something else entirely. The two numbers answer different questions: the platform fee tells you what the software costs; Meta's rates tell you what sending messages costs, and that part is the same no matter which provider you use, because it goes to Meta either way.

A Rough Way to Estimate Your Cost

Add up how many marketing, utility and authentication messages you expect to send in a month, multiply each by its category's approximate rate, then add the platform subscription. Our pricing page includes a simple calculator with illustrative rates to help you get a ballpark figure.

The Takeaway

Don't compare providers on "price" alone — compare what's included in the subscription, and treat Meta's messaging charges as a separate line item that any legitimate provider passes through rather than marks up arbitrarily.
