## Creating Action for Infobip

To send messages through Infobip, you need to create a custom action through Action Jail.

### Action Code Example

```javascript
const axios = require('axios');

// Constants for API configuration
const API_KEY = 'YOUR_API_KEY'; // Your Infobip API key
const SENDER_NAME = 'DemoCompany'; // Sender name for Viber
const BASE_URL = 'https://api.infobip.com'; // Base URL for Infobip
const API_PATH = '/viber/2/messages'; // Path for sending messages

const action_infobip_send_message = async function() {
    const j = this.getCurrentStateJSON();
    if (!j || typeof j !== 'object') {
        console.error("Error: JSON data is invalid or not an object.");
        return "error";
    }

    const message = (j.message || '').trim();
    const to = (j.to || '').trim();

    if (!message || !to) {
        console.error("Error: 'message' or 'to' is missing in the JSON data.");
        return "error";
    }

    const options = {
        method: 'POST',
        url: `${BASE_URL}${API_PATH}`,
        headers: {
            'Authorization': `App ${API_KEY}`,
            'Content-Type': 'application/json',
            'Accept': 'application/json'
        },
        data: {
            messages: [
                {
                    sender: SENDER_NAME,
                    destinations: [{ to }],
                    content: {
                        text: message,
                        type: "TEXT"
                    }
                }
            ]
        }
    };

    try {
        const response = await axios(options);
        console.log("Response from Infobip:", response.data);
        return "success";
    } catch (error) {
        console.error("Error sending message:", error.response?.data || error.message);
        return "error";
    }
};

module.exports = action_infobip_send_message;
```

---

## Usage in Scenario

### Data Preparation

Before calling the action, set variables in state:

```json
{
  "message": "Your order #123 has been shipped!",
  "to": "380971234567"
}
```

**Parameters:**
- `message` — message text to send
- `to` — recipient phone number in international format (without `+` sign)

### Result Handling

**Success (`success`):**
- If the message is successfully sent, the action returns `"success"`
- In the scenario, you can add subsequent actions (logging, status update, etc.)

**Error (`error`):**
- If an error occurred, the action returns `"error"`
- In the scenario, you should provide error handling (notify administrator, retry, etc.)

## Sending SMS via Infobip

For sending SMS, a different endpoint is used:

```javascript
const smsOptions = {
    method: 'POST',
    url: `${BASE_URL}/sms/2/text/single`,
    headers: {
        'Authorization': `App ${API_KEY}`,
        'Content-Type': 'application/json'
    },
    data: {
        from: SENDER_NAME,
        to: to,
        text: message
    }
};
```
