WhatsApp Business API vs Business App
Solo seller on one phone, or a B2B sales team on marketplace leads? Compare the WhatsApp Business app and the Official WhatsApp Business API for Indian businesses.
Official WhatsApp Business API · 30-day trial · Plans from ₹999/mo
WhatsApp Business API and the WhatsApp Business app both let businesses chat with customers, but they serve different needs. The app suits solo operators on one phone; the Official API powers multi-agent teams, automation, marketplace integrations, and CRM workflows on a verified business number — without mixing personal WhatsApp.

Frequently Asked Questions
What is the difference between WhatsApp Business API and the Business app?
The Business app runs on one phone for one user. The Official WhatsApp Business API connects your business number to a platform like BizNuma so multiple agents, automation, and marketplace integrations work on the same Official number.
Can I keep my existing WhatsApp Business number when moving to the API?
Yes. BizNuma supports guided onboarding from the WhatsApp Business app to the Official API on the same business number.
Do I need the API for IndiaMART lead auto-reply?
For instant auto-reply when IndiaMART, JustDial, or TradeIndia leads arrive — plus team inbox and pipeline — you need the Official WhatsApp Business API with a CRM like BizNuma.
Is the WhatsApp Business app enough for a 5-person sales team?
Usually not. The app has no shared inbox, no lead routing, and no marketplace sync. Teams outgrow it quickly when handling B2B enquiries at volume.
Will using the API get my number banned?
The Official WhatsApp Business API is Meta-approved. BizNuma is a Meta Tech Provider. Using approved templates and opt-in broadcasts keeps you compliant.
How much does WhatsApp Business API software cost in India?
BizNuma plans start at ₹999/mo with a 30-day trial. Meta charges separate conversation fees for API usage — see Meta's official pricing.
How long is chat history kept on BizNuma?
All plans — Starter through Scale — include 30 days of chat history on connected Official WhatsApp Business numbers.
