# Complete Guide to WhatsApp Business API Integration

WhatsApp Business API enables enterprises to communicate with customers at scale. With Zavu, you can integrate WhatsApp alongside other channels through a single unified API.

## Why WhatsApp Business API?

WhatsApp has over 2 billion active users worldwide, making it one of the most effective channels for customer communication:

- **98% open rate** compared to 20% for email
- **Rich media support** including images, documents, and interactive buttons
- **End-to-end encryption** for secure communications
- **Global reach** with presence in 180+ countries

## Setting Up WhatsApp with Zavu

### Step 1: Business Verification

First, verify your business with Meta:

```typescript
// Check verification status
const status = await zavu.whatsapp.getVerificationStatus()

console.log('Business Name:', status.businessName)
console.log('Verification Status:', status.verified)
console.log('Quality Rating:', status.qualityRating)
```

### Step 2: Configure Message Templates

WhatsApp requires pre-approved templates for outbound messages:

```typescript
// Create a new template
const template = await zavu.whatsapp.templates.create({
  name: 'order_confirmation',
  language: 'en',
  category: 'TRANSACTIONAL',
  components: [
    {
      type: 'HEADER',
      format: 'TEXT',
      text: 'Order Confirmed!'
    },
    {
      type: 'BODY',
      text: 'Hi {{1}}, your order #{{2}} has been confirmed. Expected delivery: {{3}}.'
    },
    {
      type: 'FOOTER',
      text: 'Reply HELP for assistance'
    },
    {
      type: 'BUTTONS',
      buttons: [
        { type: 'URL', text: 'Track Order', url: 'https://track.example.com/{{1}}' },
        { type: 'QUICK_REPLY', text: 'Contact Support' }
      ]
    }
  ]
})
```

### Step 3: Send Template Messages

Once approved, send template messages to customers:

```typescript
const message = await zavu.whatsapp.sendTemplate({
  to: '+1234567890',
  template: 'order_confirmation',
  parameters: {
    body: ['John', 'ORD-12345', 'January 20, 2025']
  }
})
```

## Interactive Messages

WhatsApp supports rich interactive messages:

```typescript
// Send a list message
await zavu.whatsapp.sendInteractive({
  to: '+1234567890',
  type: 'list',
  header: { type: 'text', text: 'Choose an option' },
  body: { text: 'How can we help you today?' },
  action: {
    button: 'View Options',
    sections: [
      {
        title: 'Support',
        rows: [
          { id: 'track_order', title: 'Track my order' },
          { id: 'return_item', title: 'Return an item' },
          { id: 'speak_agent', title: 'Speak to an agent' }
        ]
      }
    ]
  }
})
```

## Best Practices

1. **Respect opt-in requirements** - Only message users who have explicitly opted in
2. **Use templates wisely** - Keep templates concise and valuable
3. **Monitor quality rating** - Maintain high quality to avoid restrictions
4. **Handle responses promptly** - Users expect quick replies on WhatsApp
