Overview

Zavu delivers incoming messages to your application in real-time via webhooks. When a customer sends you a message via SMS or WhatsApp, we forward it to your configured endpoint within seconds.

How It Works

CodeCopy
Customer Message → Zavu → Your Webhook → Your Application

1. A customer sends a message to your Sender's phone number
2. Zavu receives the message from the carrier (SMS) or Meta (WhatsApp)
3. We forward the message to your registered webhook URL
4. Your application processes the message and responds if needed

Quick Start

1. Set Up Your Endpoint

Create an endpoint that accepts POST requests. Here's a minimal example:

TypeScript (Express)Python (Flask)Ruby (Sinatra)GoPHPCopy
app.post("/webhooks/zavu", (req, res) => {
  const event = req.body;

  if (event.type === "message.inbound") {
    console.log("New message from:", event.data.from);
    console.log("Message:", event.data.text);
  }

  res.status(200).send("OK");
});

2. Register Your Webhook

Configure your webhook URL in the Dashboard under your Sender settings, or via the API.

3. Start Receiving Messages

Once configured, Zavu will send message.inbound events to your endpoint whenever a customer messages you.
