Built for You
Everything you need
to build at scale
Simple REST API
Send messages with a single POST request. Clean, predictable JSON responses you can rely on in production.
Session-Bound Keys
Each API key is tied to a specific WhatsApp session. No session IDs in your requests — just the key.
Real-time Webhooks
Get instant push notifications for incoming messages, delivery receipts, and session status changes.
Multi-Session Support
Run multiple WhatsApp numbers from one account. Scale to as many sessions as your plan allows.
Message Analytics
Track delivery status, read receipts, and full message history from the dashboard or via the API.
Secure by Default
Bearer token auth, hashed key storage, and per-key revocation. Built with OWASP security best practices.
How It Works
From signup to first message
in under 5 minutes
Create a Session
Sign up, go to Sessions, click New Session, and scan the QR code with WhatsApp on your phone.
