Paperwork needed

Built for Makers,
Not Bureaucrats

Everything you need to integrate WhatsApp notifications without the enterprise friction or 3-week Meta approval process.

Zero Paperwork

Skip Meta business verification entirely. Scan a QR code with your WhatsApp and hit the API in under 3 minutes. No ID, no business docs, no waiting.

Enterprise Security

bcrypt password hashing, one-way API key hashing (never recoverable), HMAC-signed webhook payloads, and brute-force protection built into every layer.

Real-time Webhooks

Don't poll for delivery status. Register a webhook URL and receive instant POST notifications when messages are delivered, read, or fail — with auto-retry.

Message Templates

Save OTP, payment, and order message templates in the dashboard. Call them by ID from your API — no more hardcoding message strings in your codebase.

AI Support Bot

Built-in Gemini-powered support chatbot answers API questions 24/7. Setup help, integration snippets, plan info — all instantly, without opening a ticket.

Analytics Dashboard

Track messages sent, delivered, and failed in real time. Filter by session, date range, or status. CSV export for your own records and audits.

From zero to sending
in under 5 minutes

1
Create account

Sign up with email + WhatsApp number. Verify both with OTP codes. No business docs, no KYC, no waiting period.

2
Connect WhatsApp

Scan the QR code in your dashboard with WhatsApp's "Linked Devices" feature. Your session goes live instantly.

3
Call the API

Generate an API key, grab a code snippet from the Docs page, drop it in your app. Start sending in minutes, not weeks.
