WhatsApp on the web for teams — and the shared inbox behind it

Most teams reach a point where a browser tab and a personal phone stop being enough. This page explains how WhatsApp works for a business team at scale — through the official WhatsApp Business Cloud API — and what a shared inbox adds.

How business WhatsApp actually connects

If you have searched for "WhatsApp Web", you have met the consumer feature: a browser view that mirrors a phone account. That model was built for one person and one device. It is not how business messaging is meant to run at scale.

Business WhatsApp connects through the official WhatsApp Business Cloud API. You link your business number through Meta's official onboarding flow and Meta Embedded Signup, and from then on messages are delivered by Meta to your platform's endpoint. There is no phone that has to stay awake, no browser tab that can drop, and no per-device ceiling. Greenbubble does not depend on QR scanning or a linked phone session to keep your connection active — the API is the connection.

That single architectural choice is what makes everything else on this page possible: multiple agents, automation, analytics, and multi-channel.

Why the API model wins

• No device ceiling. The consumer web experience is tied to a single account on a phone. The API is not — your whole team works the same number.
• No phone dependency. Nothing drops because a phone went offline, ran out of battery, or lost Wi-Fi.
• No hidden governance gaps. Every message is attributed to an agent, with roles, assignments, and an audit trail.
• Full feature surface. Approved templates, bulk campaigns, catalogs, forms, payments, and webhooks are API-native.

What a shared inbox adds

Connecting the API gives you transport. Greenbubble gives your team a place to work:

The governance gap

When work happens through a single mirrored account, there is no way to hide a conversation from an agent, restrict who can export a contact, or prove who sent a message. For a two-person team that is tolerable. For a ten-person team with contractors, it is a problem. The moment you need to answer "who handled this and what did they promise?", a mirrored session has no answer. A shared inbox does.

When to move to the API

If you answer yes to any of these, a device-mirroring workflow has stopped fitting:

• More than a couple of people need to work the same WhatsApp number
• You want to assign conversations to specific agents
• You want SLAs ("first reply within 5 minutes")
• You want a real audit trail of who said what
• You want templates, bulk sends, or automations
• You want WhatsApp alongside Instagram, Facebook, Telegram, or web chat
• You want CRM hooks (HubSpot, Salesforce, Zoho, Pipedrive)

The move is light: connect your number to Greenbubble through Meta Embedded Signup, keep your existing phone number, and let your team work from the browser. Your customers notice nothing.

A phased rollout

1. Connect. Complete Meta Embedded Signup and route inbound messages into the shared inbox.
2. Train. Move the support team into the inbox. Set SLAs and assignments.
3. Automate. Add a welcome flow and after-hours replies.
4. Expand. Bring Instagram, Facebook, Telegram, web chat, and Click-to-WhatsApp Ads into the same workspace.
5. Measure. Track response time, resolution, and conversion per agent and per channel.

What stays the same

Your phone number, your customers, your business profile, and the green badge. The switch is invisible to customers, which is the point.

What agents gain day to day

Removing the device ceiling is the headline, but the daily wins are subtler. An agent starts the day with a queue instead of a phone. They can see which conversations are unassigned, which are breaching SLA, and which have a note from a colleague. They can hand a conversation to a specialist without asking the customer to repeat themselves. Managers can pull a report instead of sampling by memory. None of this is exotic; all of it is missing from a mirrored single-account workflow.

A note on the desktop client

Meta also offers a desktop client. It behaves like the browser view and is fine for a solo operator. It is still a window onto one account, so it does not solve the team problem. For teams, the API plus a shared inbox is the model that scales.

Frequently asked questions

How does Greenbubble connect to WhatsApp?

Through the official WhatsApp Business Cloud API, using Meta's official onboarding flow and Meta Embedded Signup. Greenbubble does not depend on scanning a QR code from a phone or keeping a device session active.

What is WhatsApp Web, then?

WhatsApp Web is Meta's consumer feature that mirrors a phone account in a browser. It was designed for one person. It is separate from the WhatsApp Business Cloud API that powers business messaging at scale.

Can multiple agents use the same WhatsApp number?

Yes. With the API and a shared inbox like Greenbubble, an unlimited number of agents work the same number with role-based access, assignments, and a full audit log.

Do I need a phone online for messages to arrive?

No. With the Cloud API, Meta delivers messages to your platform's endpoint. There is no phone that has to remain online and no session that can drop.

Is WhatsApp messaging for business secure?

Messages are encrypted in transit and the Cloud API is Meta's official, policy-compliant channel. On top of that, Greenbubble adds role-based access, audit logs, and configurable retention for governance.

Can I send broadcasts and campaigns?

Yes. The API supports approved templates and bulk campaigns. Greenbubble's bulk sender adds opt-in handling, segmentation, and rate-limit pacing.

Can I use WhatsApp alongside other channels?

Yes. Greenbubble unifies WhatsApp, Instagram, Facebook Messenger, Telegram, and website chat in one inbox, so an agent never switches tools when a customer does.

Is there a free way to start?

You can begin with a trial of Greenbubble and connect through Meta's official onboarding. Meta charges per-conversation fees, which Greenbubble passes through at cost.
