A switchboard-style inbox routing one WhatsApp number to several people

OBJ. 2026-014

The switchboard

One WhatsApp number, many careful hands.

When a business grows, one WhatsApp number is suddenly answered by several people — and without care, messages get missed, doubled, or crossed. Relay is the switchboard behind that number: it routes each conversation to the right pair of hands and keeps the whole team in step.

One line to the customer; many careful operators behind it, none of them stepping on the others.

What it does

  • 01One customer-facing number answered smoothly by a whole team
  • 02Conversations routed so nothing is missed or answered twice
  • 03Several accounts kept in step behind a single line
For the curious — the making of it

A multi-account WhatsApp relay: Fastify with BullMQ queues over whatsapp-web.js. A companion multi-user web client, Whatsup, sits alongside it.

  • Routes one number across many operators
  • Queue-backed, so messages are never dropped
  • Fastify + BullMQ + whatsapp-web.js
