# Blue in WhatsApp groups

> Add Blue's WhatsApp number to a linked WhatsApp group so your team can @mention it there.

Blue can answer in WhatsApp groups you've brought into OnSite. It joins as a WhatsApp contact, so a WhatsApp group admin adds it in WhatsApp. Blue never joins a WhatsApp group automatically.

## Add Blue to a WhatsApp group

**1. Start in OnSite**

Open the WhatsApp chat's info in OnSite and tap **Add Blue**. OnSite shows the steps under **Add Blue on WhatsApp**. On a computer, you'll also see a **Copy** button for Blue's number.

**2. Save Blue's contact**

Tap **Save contact**. Blue is saved to your phone as "OnSite Blue".

**3. Add Blue to the group**

Tap **Open WhatsApp**, open the group and add OnSite Blue as a member. Only a WhatsApp group admin can do this, unless the group lets everyone add members.

**4. Wait for Blue to join**

OnSite shows **Waiting for Blue in WhatsApp** until Blue has joined. On a computer, click **Check again**. To cancel, tap **Stop adding Blue**.

## How Blue works in WhatsApp

* Blue answers only when someone @mentions it or replies to it.
* It uses only that WhatsApp group's own messages.
* Its replies don't include links.
* Chat admins can switch **Suggest tasks and forms** and the chat's context on or off. The other [switches](https://docs.on-site.io/blue/chat-settings.md) don't apply in WhatsApp groups.

## Remove Blue

Removing Blue in OnSite stops it answering. Its number stays in the WhatsApp group until a WhatsApp group admin removes it.
