💡 Usage Examples

Basic WhatsApp Messaging

const Kirimi = require('kirimi');

async function sendWelcomeMessage() {
  const client = new Kirimi('your_user_code', 'your_secret');
  
  try {
    const result = await client.sendMessage(
      'your_device_id',
      '628123456789',
      'Welcome to our service! 🎉'
    );
    console.log('Message sent successfully:', result);
  } catch (error) {
    console.error('Failed to send message:', error.message);
  }
}

sendWelcomeMessage();

OTP Verification Flow

const Kirimi = require('kirimi');

class OTPService {
  constructor(userCode, secret) {
    this.client = new Kirimi(userCode, secret);
    this.deviceId = 'your_device_id';
  }

  async sendOTP(phoneNumber) {
    try {
      const result = await this.client.generateOTP(this.deviceId, phoneNumber);
      console.log('OTP sent:', result);
      return result;
    } catch (error) {
      console.error('Failed to send OTP:', error.message);
      throw error;
    }
  }

  async verifyOTP(phoneNumber, otpCode) {
    try {
      const result = await this.client.validateOTP(this.deviceId, phoneNumber, otpCode);
      console.log('OTP verified:', result);
      return result.verified;
    } catch (error) {
      console.error('Failed to verify OTP:', error.message);
      return false;
    }
  }
}

// Usage
const otpService = new OTPService('your_user_code', 'your_secret');

// Send OTP
await otpService.sendOTP('628123456789');

// Verify OTP (user provides the code)
const isValid = await otpService.verifyOTP('628123456789', '123456');

Media Messaging

async function sendImageMessage() {
  const client = new Kirimi('your_user_code', 'your_secret');
  
  try {
    const result = await client.sendMessage(
      'your_device_id',
      '628123456789',
      'Here is your requested document 📄',
      'https://example.com/document.pdf'

⚠️ Error Handling

The library provides comprehensive error handling. All methods throw descriptive errors:

try {
  await client.sendMessage('device_id', 'invalid_number', 'Hello');
} catch (error) {
  if (error.message.includes('Parameter tidak lengkap')) {
    console.log('Missing required parameters');
  } else if (error.message.includes('device tidak terhubung')) {
    console.log('Device is not connected');
  } else if (error.message.includes('kuota habis')) {
    console.log('Quota exceeded');
  }
  // Handle other specific errors...
}

🔒 Security Notes

• Always keep your secret key secure and never expose it in client-side code
• Use environment variables to store credentials
• Validate phone numbers before sending messages
• Implement rate limiting in your application

// Good practice: use environment variables
const client = new Kirimi(
  process.env.KIRIMI_USER_CODE,
  process.env.KIRIMI_SECRET_KEY
);

🚦 Rate Limits & Quotas

• Each message sent reduces your device quota (unless unlimited)
• OTP codes expire after 5 minutes
• Device must be in 'connected' status to send messages
• Check your dashboard for current quota and usage statistics
