The WhatsApp Business API is what separates a real WhatsApp business tool from the basic WhatsApp Business app. With the API, you can send campaigns to thousands of contacts, connect multiple agents to one number, build AI chatbots, and integrate WhatsApp with your CRM. The good news: setting up the API no longer requires a developer. Meta launched the Cloud API which any business can connect through an approved platform like WhatsGrow AI in under 15 minutes.

WhatsApp Business API (Cloud API):
Step 1: Create a Meta Business Account
1. Go to business.facebook.com

3. Complete business verification — you'll need your business registration number (for India: GST or CIN; for UAE: trade license)
4. Wait 1-2 days for Meta to verify your business
Important: Use a real business email, not a personal Gmail.
Step 2: Set Up the WhatsApp Business Platform
1. In Meta Business Suite, go to Settings > Business Assets > Add > WhatsApp Accounts

Step 4: Create and Get Approved for Message Templates
For outbound campaigns, you need approved Message Templates. Templates are pre-approved messages you submit to Meta for review. Once approved (usually within a few minutes to 24 hours), you can use them for campaign broadcasts, welcome messages, appointment reminders, and follow-up sequences.
WhatsGrow AI includes a template manager that lets you create, submit, and manage all your templates directly in the dashboard.
Step 5: Send Your First Campaign
