# Lia on a WhatsApp number that already uses another platform

**If your business's WhatsApp number is already used by another platform, there's one quick setting in Meta so Lia can receive your customers' messages.** It takes about 2 minutes, and you don't need to turn the other platform off. The video above shows every click, and the steps below follow the same path in text.

**Don't change Message routing, the top section of the tab.** That setting applies to every number in your business. Lia's setting is a separate group, the Alternate Routing group, just for the number she will handle.

## Step 1: connect the number in the RIA panel

In the RIA panel, on the **Conectar conta WhatsApp** card (Connect WhatsApp account), click **Conectar WhatsApp** (Connect WhatsApp). If the panel already has a number, the button is **Conectar conta**. The panel is in Portuguese; the video shows it translated so you can follow along. In the Meta window, open the **Phone number** list and pick the number you already use. It's already listed there, as connected. You don't need to type the number.

## Step 2: confirm the other-integration warning

Meta warns that the number is already being used in another integration. That's expected. Check the confirmation box and continue to the end of the window.

## Step 3: open the Conversation routing tab

Open https://business.facebook.com and go to **Settings** › **WhatsApp accounts**. Click your number and open the **Conversation routing** tab.

## Step 4: leave Message routing as it is

Under **Message routing**, Meta shows who handles each type of conversation. Don't change anything in this section: it applies to every number in your business.

## Step 5: create the Alternate Routing group

Scroll down to **Alternate Routing group** and click **Create**.

## Step 6: choose the number

Under **Phone numbers**, select only the number Lia will handle.

## Step 7: the four message options go to RIA

For the four message options, choose RIA:

- when the customer sends a message;
- when they reply to a click-to-WhatsApp ad;
- when they reply to a marketing campaign;
- when they reply to a notification, such as a confirmation or a reminder.

## Step 8: calls, thread control and visibility stay with the other platform

For calls (**Calls with customers**), **Thread control** and visibility, keep the platform you already use. That way your team still sees everything and can take over any conversation. Then click **Save**.

## How to test it

Send a "hi" from a phone that has never messaged your business. The reply should come from Lia.

Conversations already in progress stay with the other platform until they go idle. New ones go straight to Lia.
