High-performance API

v3 — Built for production

A clean, fast, multi-tenant WhatsApp API platform.

Build automated messaging on top of a TypeScript-first stack: Next.js 15, Baileys multi-device sockets, SQL Server persistence, real-time SSE updates, and signed webhook delivery.

High-performance

Pooled SQL connections, in-memory chat cache, exponential reconnects, background webhook queue.

Secure by default

JWT sessions, hashed API tokens, HMAC-signed webhook payloads, rate limiting per IP.

Realtime

Server-Sent Events stream live state, QR refreshes, inbound/outbound messages — no polling required.
