# Meta WhatsApp API

> Send messages using connected WhatsApp Business Cloud API accounts.

Meta WhatsApp API is used when your customer has connected a WhatsApp Business account through KarFlows.

## Conversational endpoint

```http theme={null}
POST {{baseUrl}}/api/v1/send-message?token=API_KEY
```

## Template endpoint

```http theme={null}
POST {{baseUrl}}/api/v1/send_templet?token=API_KEY
```

## When to use Meta

Use Meta WhatsApp when:

* The customer has a WhatsApp Business account connected.
* You need stable API delivery instead of a QR session.
* You need approved WhatsApp templates.
* You need official Cloud API behavior.

## Unified routing

In Unified Messaging API, include `whatsapp_meta` in `channels`.

```json theme={null}
{
  "channels": ["whatsapp_meta", "sms"],
  "deliveryMode": "fallback"
}
```

If Meta is not connected or cannot send, Unified fallback can continue to SMS when enabled.
