Send OTP via WhatsApp

Authenticate with your API key and send a one-time password in a single POST request.

send-otp.js

// 1. Firebase signup — create the user
const credential = await createUserWithEmailAndPassword(
  auth, email, password
);

// 2. Generate OTP & send via WhatsApp
const wallm = axios.create({
  baseURL: 'https://wa.llmarifa.co/whatsapp',
  headers: { 'x-api-key': process.env.WALLM_API_KEY },
});

const otp = Math.floor(100000 + Math.random() * 900000);

await wallm.post('/sessions/main/messages/text', {
  to: phone,
  text: `Your verification code is ${otp}.
It expires in 5 minutes.`,
});

// 3. Verify OTP on your backend to complete signup
// Store the OTP hashed, verify when user submits it,
// then activate the Firebase account.

AI reply to inbound messages

Receive inbound messages via webhook, process with OpenAI, and reply automatically.

webhook-handler.js

// Webhook endpoint — point Wallm here
app.post('/webhook', async (req, res) => {
  const { event, data } = req.body;

  // Only handle incoming text messages
  if (event !== 'messages.upsert') return res.sendStatus(200);
  if (data.key.fromMe) return res.sendStatus(200);

  const text = data.message?.conversation;
  if (!text) return res.sendStatus(200);

  // Get AI response
  const ai = await openai.chat.completions.create({
    model: 'gpt-4o-mini',
    messages: [
      { role: 'system', content: 'Reply in Arabic. Be helpful.' },
      { role: 'user', content: text },
    ],
  });

  // Send reply back through the API
  await wallm.post('/sessions/main/messages/text', {
    to: data.key.remoteJid,
    text: ai.choices[0].message.content,
  });

  res.sendStatus(200);
});
