WhatsApp has over 2 billion active users worldwide. For most businesses in India, Southeast Asia, Latin America and the Middle East, it's already the #1 channel customers use to reach them. The WhatsApp Business API turns this into a scalable platform — but it's easy to get lost in Meta's documentation. This guide cuts through it.
What is the WhatsApp Business API?
The WhatsApp Business API (officially called the WhatsApp Cloud API) is Meta's official platform for businesses to send and receive WhatsApp messages programmatically. Unlike the WhatsApp Business App (the free app on your phone), the API is designed for teams:
- Multiple team members can handle the same WhatsApp number
- You can automate messages, chatbot flows and broadcast campaigns
- You can integrate with your CRM, e-commerce platform and payment gateway
- You can use AI to auto-reply to customer queries at scale
WhatsApp Cloud API vs WhatsApp Business App — what's the difference?
| Feature | WhatsApp Business App | WhatsApp Cloud API |
|---|---|---|
| Users per number | 1 device | Unlimited team members |
| Automation | Basic auto-reply only | Full chatbot flows, AI replies |
| Broadcasts | Up to 256 contacts | Thousands of contacts |
| Integrations | None | CRM, e-commerce, payments |
| Cost | Free | Meta conversation fees + platform |
| Scale | Manual only | Fully programmable |
How does WhatsApp API pricing work?
Meta charges per conversation, not per message. A conversation is a 24-hour window of messages between your business and one customer. There are two types:
- User-initiated conversations — when a customer messages you first. These are free for the first 1,000 conversations per month.
- Business-initiated conversations — when you message a customer first (broadcasts, notifications). These cost ~$0.005–$0.08 per conversation depending on country.
On top of Meta's fees, you pay your WhatsApp platform (like Waqly) a flat monthly subscription. Waqly charges from $29/month — with no markup on Meta fees or AI usage.
How to get WhatsApp Business API access
You need a Meta Developer account and a verified business. Here's the 5-step process:
WhatsApp message types you can send
The API supports several message types:
- Text messages — plain text with optional formatting (bold, italic, lists)
- Media messages — images, videos, audio, documents, stickers
- Template messages — pre-approved messages for business-initiated conversations (broadcasts)
- Interactive messages — buttons (up to 3) and list messages (up to 10 rows)
- Reaction messages — emoji reactions to messages
What you cannot do on the WhatsApp API
- Send unsolicited messages to customers who haven't opted in
- Send promotional messages without using an approved template
- Use the API for spam or bulk cold outreach
- Create groups or broadcast lists (only individual conversations)
Breaking these rules risks your phone number being flagged or permanently banned. Waqly is built on the official API, so all messaging goes through Meta's policy layer — you're protected.
