What is this?

A complete WhatsApp Business API platform with:

• MCP Server — Type "send a WhatsApp message" in Cursor or Claude Code and it just works
• REST API — 6 endpoints: send message, send template, send media, broadcasts, webhooks, contacts
• TypeScript SDK — npm install @gaviwhatsapp/whatsapp
• Python SDK — pip install gaviwhatsapp
• Dashboard — Visual form builder, conversation flows, broadcast campaigns, analytics

Quick Start

Option 1: MCP Server (AI coding tools)

Add to .cursor/mcp.json or .claude/mcp.json:

{
  "mcpServers": {
    "gaviwhatsapp": {
      "command": "npx",
      "args": ["@gaviwhatsapp/mcp", "--api-key", "gv_YOUR_KEY"]
    }
  }
}

Then just ask: "Send a WhatsApp message to +919876543210 saying hello"

Option 2: TypeScript SDK

npm install @gaviwhatsapp/whatsapp

import { WhatsApp } from '@gaviwhatsapp/whatsapp'

const wa = new WhatsApp({ apiKey: process.env.GAVIWHATSAPP_API_KEY! })
await wa.send({ to: '+919876543210', text: 'Hello from my app!' })

Option 3: Python SDK

pip install gaviwhatsapp

from gaviwhatsapp import WhatsApp

wa = WhatsApp(api_key="gv_YOUR_KEY")
wa.send(to="+919876543210", text="Hello from my app!")

Option 4: REST API

curl -X POST https://www.gaviventures.com/api/v1/messages \
  -H "Authorization: Bearer gv_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"to": "+919876543210", "text": "Hello!"}'
