Cost Breakdown
WhatsApp Business App Costs
Completely free. Meta charges nothing to download, register, or use any core App feature.
WhatsApp Business API Costs
Meta charges per conversation (24-hour window), not per message. Four pricing categories apply:
-
Marketing conversations — highest rate; for campaigns and promotions
-
Utility conversations — mid-rate; for transactional messages like order receipts
-
Authentication — mid-rate; for OTPs and verification flows
-
Service conversations — lowest rate; for customer-initiated support
BSPs add platform or seat fees typically $50 to $500+ per month on top of Meta's charges. Businesses with developer resources can use Meta Cloud API directly to eliminate this extra cost layer.
Migrating from App to API
Migration preserves your phone number but erases all chat history. Export all conversations before you start.
-
Export all chat history from the WhatsApp Business App.
-
Choose a BSP (Twilio, WATI, Interakt, Weflux) or set up Meta Cloud API directly.
-
Remove the number from the App — only one platform can own a number at a time.
-
Verify the number in your BSP platform or Meta Business Manager.
-
Submit Message Templates for Meta review and approval.
-
Integrate your CRM or chatbot platform and run end-to-end flow tests.
Final Verdict
Both tools serve real business needs the App removes friction for small operators, the API removes limits for scale-ready teams. The worst move is choosing the App due to cost hesitation and then hitting a growth ceiling at 10x the volume you need to handle.
