### Send()

```typescript
async Send({
  recipients,
  messages,
  from
}: {
  recipients: string | string[];
  messages: string | string[];
  from?: string | string[];
}): Promise<IVesalResponse_Send_WithCount>
```

Sends SMS messages to one or multiple recipients.

**Parameters:**
- `recipients` - Phone number(s) to send to (e.g., `'09123456789'` or `['09123456789', '09987654321']`)
- `messages` - Message content(s) to send
- `from` - (Optional) Sender number(s), defaults to the number set in constructor

  errorModel: {
    errorCode: number,
    timestamp: string | number | null
  }
}
```

#### Send Methods

**One-to-Many (Same message to multiple recipients):**
```typescript
await client.Send({
  recipients: ['09123456789', '09987654321'],
  messages: 'Hello everyone!'
});
```

```

Gets the delivery status of sent messages.

```typescript
{
  states: Array<{
    id: number,      // Reference ID
    state: number    // Status code (see Message States below)
  }>,
  errorModel: {
    errorCode: number,
    timestamp: string | number | null
  }
}
```

**Example:**
```typescript
const sendResult = await client.Send({

  messages: 'Test message'
});

// Wait a bit for delivery
await new Promise(resolve => setTimeout(resolve, 5000));

const statusResult = await client.GetMessageStatus(sendResult.references);
console.log(statusResult.states);

    messages: 'Test'
  });
} catch (error) {
  if (error instanceof VesalError) {
    console.error(`Vesal Error ${error.status}: ${error.message}`);
  } else {
    console.error('Unexpected error:', error);
  }
}
```

## Complete Example

```typescript
import { Vesal, VesalError, messageStates } from 'vesal';

async function main() {
  // Initialize client
  const client = new Vesal(
    'your-username',
    'your-password',
    '50002710000000'
  );

  try {
    // Check account info
    const userInfo = await client.GetUserInfo();
    console.log(`Credit: ${userInfo.user.credit}`);
    console.log(`Active: ${userInfo.user.active}`);

    // Send SMS
    const sendResult = await client.Send({
      recipients: ['09123456789', '09987654321'],
      messages: 'Hello from Vesal!'
    });

    console.log(`Successfully sent: ${sendResult.count.success}`);
    console.log(`Failed: ${sendResult.count.fail}`);

    // Check status after a delay
    await new Promise(resolve => setTimeout(resolve, 10000));

    const validRefs = sendResult.references.filter(
      ref => typeof ref === 'number'
    ) as number[];

    if (validRefs.length > 0) {
      const status = await client.GetMessageStatus(validRefs);
      status.states.forEach(state => {
        console.log(
          `Message ${state.id}: ${messageStates[state.state]}`
        );
      });
    }

    // Check received messages
    const received = await client.GetReceivedMessages();
    console.log(`Received ${received.messageModels.length} messages`);

  } catch (error) {
    if (error instanceof VesalError) {
      console.error(`Error ${error.status}: ${error.message}`);
    } else {
      console.error('Unexpected error:', error);
    }
  }
}

main();
