SDKWA Multi-Messenger API Client for JavaScript

A modern JavaScript/TypeScript SDK for integrating with multiple messenger platforms through the SDKWA HTTP API.

Supported Messengers:

• 🟢 WhatsApp - Full support for messaging, media, groups, and webhooks
• 🔵 Telegram - Full support for messaging, app creation, and authentication

Switch between messengers with a single parameter. All 40+ API methods work with both platforms.

Installation

npm install @sdkwa/whatsapp-api-client

Quick Start

1. Link Your Account (Required First)

⚠️ Before sending messages, scan QR code with your mobile app:

import SDKWA from "@sdkwa/whatsapp-api-client";

const sdkwa = new SDKWA({
  idInstance: "YOUR_ID_INSTANCE",
  apiTokenInstance: "YOUR_API_TOKEN_INSTANCE"
});

// Get QR code
const qrCode = await sdkwa.getQr();
console.log(qrCode.message); // base64 image - scan with WhatsApp/Telegram app

// Check authorization
const state = await sdkwa.getStateInstance();
console.log(state.stateInstance); // "authorized" when ready

📱 WhatsApp: Settings → Linked Devices → Link a Device
📱 Telegram: Settings → Devices → Link Desktop Device

2. Send Messages

// Send to WhatsApp (default)
await sdkwa.sendMessage({
  chatId: "[email protected]",
  message: "Hello WhatsApp!"
});

// Send to Telegram (override)
await sdkwa.sendMessage({
  chatId: "@username",
  message: "Hello Telegram!"
}, 'telegram');

3. Receive Messages (Webhooks)

import express from "express";

const app = express();
app.use(express.json());

sdkwa.webhookHandler.onIncomingMessageText((data) => {
  console.log("Received:", data);
});

app.post("/webhook", sdkwa.webhookHandler.webhookHandler());
app.listen(3000);

Messenger Selection

// Set default messenger
const sdkwa = new SDKWA({
  idInstance: "YOUR_ID",
  apiTokenInstance: "YOUR_TOKEN",
  messenger: "whatsapp" // or "telegram"
});

// Use default
await sdkwa.getSettings();

// Override per call
await sdkwa.getSettings('telegram');
await sdkwa.sendMessage(params, 'telegram');

All 40+ methods support both messengers: Account, Messaging, Files, Groups, Contacts, Notifications, etc.

Telegram App Creation

// 1. Send confirmation code
await sdkwa.sendConfirmationCode({ phoneNumber: 712345678989 });

// 2. Sign in with code
await sdkwa.signInWithConfirmationCode({ code: "received_code" });

// 3. Create app
await sdkwa.createApp({
  title: "My App",
  shortName: "myapp",
  url: "https://sdkwa.pro",
  description: "My app"
});
