One WhatsApp Business account · up to 4 devices linked · Chrissy + trusted staff (Marius etc.) all see the same conversations and can reply. No API approval wait. Works today.
Chrissy's WhatsApp Business phone is the master. Everyone else is a "linked device" and shows up in the same conversations. Chrissy retains full control — she can revoke any device at any time from her phone.
The regular WhatsApp Business app · not personal WhatsApp · not any Meta browser app.
On Android: Settings icon (bottom right) → Linked devices. On iPhone: Settings tab (bottom right) → Linked devices.
WhatsApp shows a QR scanner. Chrissy points it at whatever browser wants to link (her own laptop, Marius's laptop, etc.). One scan per device.
Anyone with Chrissy's phone can otherwise scan a new device. This step forces face/fingerprint before scanning.
Opens web.whatsapp.com in a new tab.
Use the "Linked devices → Link a device" flow from §1 above.
Stays logged in on that laptop indefinitely · no need to re-scan every session.
On desktop: bookmark it. On tablet: browser menu → "Install as app" · gives you a WhatsApp Business app icon that opens straight to the web session.
Anyone Chrissy links can see + send from her business number. They see every guest conversation. Only link people she trusts to represent Wishwood in writing.
Chrissy can revoke any device from her phone instantly — Linked Devices → tap the device → "Log out". That device is dead within seconds.
His own browser · his own device · his own home screen.
WhatsApp Business on Chrissy's phone → Linked devices → Link a device → scan the QR shown on Marius's browser.
He sees every conversation Chrissy sees. Sends and receives as Wishwood. Notifications go to his device too.
Cap is 4 linked devices total (excluding the master phone). If Chrissy needs more, use WhatsApp Business API via Twilio (still worth setting up in the background — but you don't need it to start).
WhatsApp Web Multi-Device works well for a small operator. It's not the same as the full WhatsApp Business API. Specifically:
Multi-Device works today. The Twilio Business API path is worth completing in the background so the hub AI can auto-send later. Steps to run in parallel:
Chrissy, Marius, and up to 2 more devices all see Wishwood messages inside 24 hours. Zero delay.
Fill in §5A on the credentials page · Twilio takes 1-2 weeks to approve. When approved, hub AI gets auto-send capability alongside the Multi-Device browsers.
Multi-Device browsers stay live for manual replies · Twilio handles automated confirmations, reminders, and check-in messages. Best of both.
