How to Connect WhatsApp to a Shared Inbox by QR Code

What does it mean to connect WhatsApp to a shared inbox by QR code?

It means adding your team’s inbox as a linked device on the WhatsApp account that already lives on your phone. WhatsApp lets one primary phone link companion devices such as WhatsApp Web, the desktop app or a tablet, and the usual way to link one is to scan a QR code (WhatsApp Help Center). whatsappx.si uses this same feature: after one scan, your workspace is one of the devices linked to the phone, recent chats sync in, and everyone on the team can read and reply from one shared inbox at the same time.

Nothing about the number changes. The WhatsApp or WhatsApp Business app stays on the phone with its profile, contacts and chats. You do not need a new SIM, a Meta developer account or a verification call. The number stays on the free WhatsApp or WhatsApp Business app rather than Meta’s paid platform, so Meta’s per-message platform fees do not apply. That is why QR linking is the fastest way to start. The official WhatsApp Business Platform (Cloud API) is the second way to connect, and the right one for volume, templates and automation at scale; more on that at the end.

Is your number ready to connect?

Before you scan anything, check three things. They decide whether the number stays healthy once a team is replying from it.

A quick readiness checklist:

How do you connect WhatsApp to a shared inbox step by step?

The whole process takes a few minutes. These steps describe whatsappx.si.

1. Create a workspace and choose “Scan QR”. Sign in to whatsappx.si with your email and password or Google account, open a workspace, add a WhatsApp number and choose the Scan QR option. A QR code appears on screen.
2. Open Linked devices on the phone. In WhatsApp or WhatsApp Business, go to Settings, tap Linked devices, then Link a device. WhatsApp’s instructions say to “point your primary phone at the screen of the device you want to link to, and scan the QR code” (WhatsApp Help Center).
3. Scan the code. The workspace now shows up in the phone’s list of linked devices, alongside any WhatsApp Web or desktop sessions.
4. Wait for recent chats to sync. Recent conversations and contacts load into the shared inbox. Keep the phone online until the sync finishes; on a busy number this can take a few minutes.
5. Invite your teammates by email. Each person gets an expiring invite link and a role: owner, admin or agent. Agents see only the chats assigned to them. Teammates never scan the QR code themselves; they sign in with their own accounts and share the one connection.
6. Reply together. Open a chat, answer the customer, assign the conversation to a colleague, and watch unread counts drop. New messages arrive live, and images and documents show inline.

What syncs into the inbox after you scan?

Once connected, you can switch on keyword-triggered auto-replies: when an incoming message contains a keyword you set, whatsappx.si sends your saved reply. Each rule can be turned on or off and shows how many times it has run. Teammates can also search your knowledge-base articles to find answers while they reply. Auto-replies answer people who wrote in; they are not a broadcast tool.

Does your phone need to stay online?

Not every minute, but it must stay in use. WhatsApp states that linked devices “work without your phone online, but will log out if your phone is unused for over 14 days” (WhatsApp Help Center), and that you need to log in on the primary phone every 14 days to keep linked devices connected (How to link a device). In practice:

• Open WhatsApp on the primary phone at least once a week. That resets the 14-day clock with margin to spare.
• Keep the phone charged and on Wi-Fi. Switched off for a few hours is fine; wiped, lost or left in a drawer for weeks is not.
• Count your linked devices. WhatsApp allows “up to four devices at a time”, and the whatsappx.si workspace counts as one. If a fifth is needed, unlink an old WhatsApp Web session first.
• A linked device cannot become the primary device. The account still belongs to the phone.

If the link drops, open the Scan QR option again and rescan from the phone. Your workspace and teammates stay in place.

How do you keep the number safe once the team is replying from it?

A shared inbox makes it easy for several people to send a lot of messages quickly. That is exactly what to avoid on a linked device. These rules follow from WhatsApp’s own terms, which prohibit “bulk messaging, auto-messaging, auto-dialing, and the like” (WhatsApp Terms of Service).

WhatsApp has also said it may act on off-platform evidence, including public claims by companies about using WhatsApp in ways that violate its terms (WhatsApp Help Center). That is why whatsappx.si has no bulk broadcast feature and never promises that a number is safe from restrictions.

How does whatsappx.si compare with other team inboxes?

whatsappx.si is a shared inbox for teams. Its main way to connect is the QR scan in this guide; it can also connect numbers through Meta’s official WhatsApp Business Platform with Embedded Signup inside the app. The QR option is built on WhatsApp’s linked-device feature, not on the official API, so the four-device cap, the 14-day phone rule and the no-bulk rule all apply.

As of October 2026, several well-known team inboxes, including Wati, respond.io, Trengo, Gallabox and Interakt, connect numbers through Meta’s official platform, and each offers Meta’s Coexistence flow so a business can keep using the WhatsApp Business app on the same number (Wati, respond.io, Trengo, Gallabox, Interakt). Those products are stronger on official standing: Coexistence runs on Meta’s platform, and all five describe themselves as Meta Business Partners on their own sites. Wati and Gallabox say Coexistence can sync up to about six months (180 days) of 1:1 chat history, while respond.io’s help center says it does not import history. Coexistence has its own limits: it requires a WhatsApp Business app number, not a personal WhatsApp number, it runs at a fixed 20 messages per second (Meta for Developers), and Meta bills its per-message fees on the API side (Meta pricing).

Also as of October 2026, Periskope, like whatsappx.si, links regular WhatsApp and WhatsApp Business app numbers by QR code (Periskope Docs). It is stronger for WhatsApp group management and operations tooling such as tickets, SLA rules and team analytics, and it states it does not support WhatsApp Business API numbers (Periskope).

QR linking in whatsappx.si fits a small team that wants to answer the number customers already know, with history, assignment, roles and keyword auto-replies, without Meta platform fees or a new number. It is not a fit for outbound campaigns, template messaging or automation at scale.

When should you use the official WhatsApp Business Platform instead?

Switch to, or add, an official number when any of these is true:

• You need to message people outside a conversation they started. On the platform, approved template messages are the only way to reach someone outside the 24-hour customer service window (Meta for Developers). whatsappx.si lets you create templates and sync them with Meta for official numbers.
• You expect real volume. Meta’s platform is its sanctioned route for scale. Its messaging limits cap how many people a business can reach outside a customer service window in a moving 24-hour period, starting at 250 for new business portfolios and scaling up from there (Meta for Developers). A QR-linked number should stay at the pace of a person replying.
• You do not want a phone in the loop. Official numbers are not tied to a handset or the 14-day rule, and a workspace can hold several of them.

Meta charges its own per-message fees on the official platform, billed separately from any software subscription (Meta pricing). You can run both in one whatsappx.si workspace: a QR-linked number for everyday replies plus official numbers for templates and volume, all in the same shared inbox.

How do you get started?

Check the readiness list above, especially the 15–20 day rule for a new number. Then create a workspace, choose Scan QR, scan the code from Settings → Linked devices on your phone, wait for the sync, and invite your first teammate. Keep your sending conversational, in batches of 5–10 to people who opted in, and add an official number later if your needs grow.
