- 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!"}'
