  • Node.js >= 20.0.0

Quick Start

import { SembojaWaClient } from '@semboja/wa';

const client = new SembojaWaClient({
  token: 'your_api_token',
  defaultDeviceId: 'my-device', // Optional: default device for all operations
});

// Send a text message
await client.messages.sendText({
  to: '6281234567890',

});

Features

  • Zero runtime dependencies - Uses native Node.js fetch API
  • Full TypeScript support - Comprehensive type definitions
  • All message types - Text, image, document, audio, video, sticker, list, buttons
  • Device management - Create, list, delete devices with QR code pairing
  • Webhook configuration - Manage webhook endpoints for real-time notifications
  • Batch messaging - Send messages to multiple recipients
  • Automatic retries - Built-in retry logic with exponential backoff
  • Quota tracking - Monitor API usage and limits

Usage

Client Configuration

import { SembojaWaClient } from '@semboja/wa';

// Simple initialization with just token
const client = new SembojaWaClient('your_api_token');

// Full configuration
const client = new SembojaWaClient({
  token: 'your_api_token',
  baseUrl: 'https://uwa.semboja.tech', // Default
  timeout: 30000, // 30 seconds (default)
  retries: 3, // Number of retries (default)
  defaultDeviceId: 'my-device', // Optional
});

Device Management

// List all devices
const devices = await client.devices.list();

// Create a new device
const device = await client.devices.create({ device_id: 'my-device' });

// Get device details
const device = await client.devices.get('my-device');

// Get QR code for pairing
const qr = await client.devices.getQrCode('my-device');
console.log(qr.qrCode); // Data URL for QR image
console.log(qr.rawQr);  // Raw QR string

// Check if device is connected
const isConnected = await client.devices.isConnected('my-device');

// Reconnect a disconnected device
await client.devices.reconnect('my-device');

// Delete a device
await client.devices.delete('my-device');

import {

  ServerError,
  NetworkError,
  TimeoutError,
} from '@semboja/wa';

try {
  await client.messages.sendText({
    to: '6281234567890',
    text: 'Hello!',
  });
} catch (error) {
  if (error instanceof AuthenticationError) {
    console.error('Invalid API token');
  } else if (error instanceof DeviceNotConnectedError) {
    console.error(`Device ${error.deviceId} is not connected`);
    // Attempt to reconnect or show QR code
    const qr = await client.devices.getQrCode(error.deviceId);
  } else if (error instanceof QuotaExceededError) {
    console.error('Message quota exceeded');
  } else if (error instanceof ValidationError) {
    console.error('Invalid request:', error.message);
  } else if (error instanceof RateLimitError) {
    console.error(`Rate limited. Retry after ${error.retryAfter}s`);
  } else if (error instanceof NotFoundError) {
    console.error('Resource not found');
  } else if (error instanceof ServerError) {
    console.error('Server error, please retry');

  } else if (error instanceof TimeoutError) {
    console.error('Request timed out');
  }
}

Phone Number Format

Phone numbers should include the country code without the + prefix:

// All these formats work
await client.messages.sendText({ to: '6281234567890', text: 'Hello' });
await client.messages.sendText({ to: '+6281234567890', text: 'Hello' }); // + will be removed
await client.messages.sendText({ to: '+62 812-3456-7890', text: 'Hello' }); // Spaces/dashes removed

Important Notes

This SDK connects to an unofficial WhatsApp API gateway. Using unofficial WhatsApp APIs may violate WhatsApp's Terms of Service and could result in your phone number being banned. Use at your own risk.

For official WhatsApp Business API integration, consider using @semboja/connect instead.
