WhatUp

Your WhatsApp number, hosted. One API.

Bring your own number, pair it by scanning a QR code, and drive it with an API key — sending, receiving, webhooks, and a resumable event stream, without babysitting a socket.

Pair in the browser

Scan a live QR from your dashboard — no credential relay, your number stays yours.

Keys, not tokens

Scoped API keys drive only your numbers, over REST and a resumable WebSocket.

One number, one process

Each number runs isolated with a singleton lease — no 440 conflict storms.
