@rmyndharis/openwa

Official JavaScript/TypeScript SDK for the OpenWA WhatsApp API Gateway.

Ships dual CJS + ESM builds with bundled type declarations.

Install

npm install @rmyndharis/openwa

Requires Node.js >= 18 (relies on the global fetch).

Usage

import { OpenWAClient } from '@rmyndharis/openwa';

const client = new OpenWAClient({
  baseUrl: 'https://your-gateway.example.com',
  apiKey: 'owa_k1_…',
});

await client.sessions.start('my-session');

const result = await client.messages.sendText('my-session', {
  chatId: '628123456789@c.us',
  text: 'Hello from the OpenWA SDK!',
});
console.log(result.messageId);

CommonJS consumers use require('@rmyndharis/openwa') identically.

Messaging

Voice notes: pass ptt: true to sendAudio to send a real WhatsApp voice note (PTT). Supply audio/ogg; codecs=opus audio for reliable playback; the server defaults the mimetype to that when ptt is set without one.

Errors

Non-2xx responses throw a typed OpenWAApiError subclass (OpenWAAuthError, OpenWAForbiddenError, OpenWANotFoundError, OpenWAConflictError, OpenWARateLimitError, OpenWANotImplementedError), each carrying .status and the parsed .body. Timeouts throw OpenWATimeoutError. The SDK does not retry — wrap calls with your own backoff if needed.
