# Connecting your WhatsApp number

To send and receive messages in BatZap, connect a WhatsApp number by scanning a QR code. This is the same pairing flow as WhatsApp Web.

## Connect a number

1. Open **Integrations** from the sidebar.
2. Click **"+ New Integration"** and choose **"WhatsApp Business"**.
3. On the **WhatsApp Integration** page, click **"Generate New QR Code"**.
4. On your phone, open **WhatsApp → Linked Devices** and point it at the QR code on screen.
5. When it pairs, the status changes to **"Connected"** and your recent conversations begin syncing into the Inbox.

⚠️ The QR code expires after a short time for security. If it expires, click **"Generate New QR Code"** and scan again.

## Connection status

The WhatsApp Integration page shows the **Connection Status**: the connected number and since when. The badge reads **"Connected"** when active and **"Disconnected"** when the session drops.

## Reconnect after a disconnection

If your number disconnects, the Inbox shows a red banner: **"WhatsApp Disconnected"**.

1. Click **"Reconnect"** in the banner.
2. Scan the QR code in the **"Reconnect WhatsApp"** window with your phone.
3. The window closes automatically once it reconnects.

While disconnected, you cannot send messages. The composer shows **"WhatsApp disconnected · Cannot send messages"**.

## Sync messages

Use the **"Sync Messages"** action to pull your recent WhatsApp conversations into BatZap. Syncing runs in the background, so you can keep working.

## Choosing which number sends (multiple numbers)

If your plan has more than one connected number, group conversations let you pick which number sends the message, using the **"Sender Number"** selector in the chat header.

In one-on-one conversations the sender number is fixed to the number that owns that contact.

## Disconnect a number

On the WhatsApp Integration page, open the **"Disconnect WhatsApp"** section and click **"Disconnect"**, then confirm. You will need to scan the QR code again to reconnect.

💡 The Standard Plan includes **1 WhatsApp number**. To connect more numbers, check your plan in **Billing**.
