There are two types of WhatsApp business tools: the WhatsApp Business app (free, limited) and the WhatsApp Business API (paid, powerful). If you're serious about using WhatsApp for marketing and automation, you need the API. Here's what you need to know.
WhatsApp Business App vs API
The free WhatsApp Business app is fine for small businesses handling 10–20 messages per day. But it has severe limitations:
- Only one device per account
- No automation (you respond manually)
- Limited broadcast (only to contacts who saved your number)
- No CRM integration
- No chatbot capabilities
The WhatsApp Business API removes all of these limitations — but it requires going through a Meta-approved Business Solution Provider (BSP).
How the API Works
The API connects your WhatsApp business number to your software systems. This enables:
- Unlimited contacts without them needing to save your number first
- Automated messages triggered by events (new lead, appointment, order)
- Chatbot flows with buttons and list menus
- Bulk broadcast campaigns to opted-in contacts
- Multi-agent team inbox (multiple people can handle messages)
- Full CRM and automation integration
API Costs in India

We build the systems, automations, and marketing strategies described in this article — for Indian businesses like yours.
Meta charges per conversation (a 24-hour window). As of 2025, rates in India:
- Business-initiated conversations: ₹0.90–2.00 per conversation
- User-initiated conversations: Free for the first 1000/month
In practice, for most SMEs sending 1,000–5,000 messages/month, the API cost is ₹1,000–5,000/month. BSPs charge an additional platform fee.
Getting Started
The process to get WhatsApp Business API access: Apply through a BSP → verify your Facebook Business Manager → get your phone number verified → apply for message templates. This takes 1–2 weeks.
