The WhatsApp shared inbox your whole team can work from
Connect your WhatsApp Business API number to one shared inbox where every agent can see, claim, and reply to conversations, with assignment, auto-routing, and a full audit trail built in.
What is a WhatsApp shared inbox?
A WhatsApp shared inbox is a team platform connected to your WhatsApp Business API number. Instead of one person holding the phone or laptop logged into the WhatsApp Business app, your whole support team logs into a central tool where every incoming WhatsApp message lands in a shared queue, ready to be claimed, assigned, and answered.
It solves the exact problem that trips up growing teams on WhatsApp: the standard app supports one primary device, so the moment you have more than two or three people who need to reply, someone has to share a login, pass around a phone, or risk two agents answering the same customer twice. A shared inbox removes that ceiling entirely, and it’s the reason every team serious about WhatsApp support eventually moves to one. For the full technical setup, see our step-by-step WhatsApp shared inbox guide.
How assignment and routing work
A shared inbox is only as good as its routing. Here’s exactly how conversations get from “just arrived” to “handled by the right person” in Resolvenyx.
Any agent can assign a conversation to themselves or a teammate with one click, right from the inbox.
Route new conversations automatically based on keywords, tags, channel, or time of day, so the right team sees them first.
Resolvenyx tracks each agent’s active conversation count and sends new chats to whoever has the fewest open.
Every conversation that hasn’t been claimed yet sits in a dedicated, visible queue, not buried in a shared inbox nobody owns.
Create separate inboxes for Sales, Support, or Billing, each with its own routing, while still sharing one WhatsApp number.
Agents are notified instantly the moment a conversation is assigned to them, so nothing waits in a queue unnoticed.
One inbox, not just for WhatsApp
In Resolvenyx, the same shared inbox also handles Instagram DMs, Facebook DMs, Gmail/Outlook/SMTP email, and website chat. Your team works from one queue with one set of assignment and routing rules, instead of learning a shared-inbox tool for WhatsApp and a separate helpdesk for everything else. See the full multi-channel inbox feature set, or read more about WhatsApp customer support generally.
Still sharing one WhatsApp Business app login?
The WhatsApp Business app supports one primary device (or a handful with Multi-Device), with no assignment, no routing, and no audit trail. Once your team passes two or three people replying regularly, it becomes the bottleneck. See exactly why in our WhatsApp Business with multiple users breakdown.
Frequently asked
What is a WhatsApp shared inbox?
A WhatsApp shared inbox connects your WhatsApp Business API number to a team platform so every agent can see, claim, and reply to conversations from one place, with assignment, routing, and a full audit trail, instead of one person holding a single device logged into the WhatsApp Business app.
How is this different from the WhatsApp Business app?
The WhatsApp Business app only supports one primary device (or a small number with Multi-Device), with no way to assign conversations, no routing rules, and no visibility into who's handling what. A shared inbox runs on the WhatsApp Business API instead, which was built for exactly this: many agents, one number, full accountability.
Can conversations be assigned automatically?
Yes. Resolvenyx supports manual assignment (agents claim conversations with one click), auto-routing rules based on keywords, tags, or time of day, and workload balancing that distributes new conversations to whichever agent has the fewest open chats.
What happens to conversations nobody has claimed yet?
They sit in a dedicated unassigned queue, visible to the whole team, so nothing silently falls through the cracks the way it can in a shared phone or single-device app.
Does a WhatsApp shared inbox include other channels too?
In Resolvenyx, yes. The same shared inbox also handles Instagram DMs, Facebook DMs, Gmail/Outlook/SMTP email, and website chat, so your team works from one queue instead of switching between apps.
How long does it take to set up?
Most teams are live within a day. You'll need a Meta Business Manager and a phone number dedicated to the WhatsApp Business API; Resolvenyx handles the technical connection through Meta's embedded signup flow. See our full setup guide for the exact steps.
