Build an Auto-Reply Support Bot

Create an automated WhatsApp support agent by combining incoming webhooks with our messaging APIs.

Bot Architecture Pattern

1. Customer messages your WhatsApp number -> 2. Waplix sends a message.received callback -> 3. Your server processes the message and matches keywords -> 4. Your server triggers Waplix /messages/send to answer.

// Example auto-reply node script
app.post("/webhook", (req, res) => {
  const { event, from, message } = req.body;
  res.status(200).json({ success: true }); // Quick ack

  if (event === "message.received" && message.toLowerCase().includes("help")) {
    sendResponse(from, "Welcome to Support! Reply with 1 for Hours, 2 for Billing.");
  }
});
