# Connect bitbybit Commerce to WhatsApp Coexistence Catalog
> Link products in bitbybit Commerce to your WhatsApp catalog when your number is connected through WhatsApp Coexistence / Business.
When your WhatsApp number is connected through **WhatsApp Coexistence / Business**, the WhatsApp Catalog toggle in Commerce cannot activate on its own. This page walks you through a one-time manual link between your bitbybit Commerce catalog and WhatsApp Manager so that products managed in bitbybit appear in your WhatsApp catalog. After the link is set, enabling or disabling a product in Commerce stays in sync with WhatsApp.
## Before you start
* You are the admin of the connected **Meta Business Account (MBA)** and can access [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager).
* Your WhatsApp number is already connected to bitbybit through **WhatsApp Coexistence / Business**. See [Connect WhatsApp Business App with Coexistence](/bitchat/how-to-create-and-connect-bitbybit-using-meta-coexistance).
* You have at least one product ready in [Commerce → Products](https://app.bitbybit.studio/commerce/products).
* Know your **Company ID** — find it at [Settings → Company](https://app.bitbybit.studio/settings?section=company). You will use it to identify the correct catalog in Step 3.
Steps 1 through 3 are a one-time setup. Once the catalog is linked, you only need to toggle products on or off in Commerce — the sync is automatic from that point.
## Step 1: Confirm no catalog is connected on your WhatsApp number
The WhatsApp number can only be linked to one catalog at a time. Before linking the bitbybit catalog, clear both places where a catalog might already be attached.
1. On mobile, open the **WhatsApp Business** app and confirm no catalog is set under **Settings → Business tools → Catalog**. If a catalog exists there, remove it.
2. Open [WhatsApp Manager](https://business.facebook.com/latest/whatsapp_manager) and go to **Account tools → Catalogue**.
3. In the top-right business selector, choose the **Meta Business Account** connected to bitbybit.
4. In the phone number selector inside the Catalogue card, choose the **WhatsApp number** connected to bitbybit.
Double-check both selectors before continuing. Disconnecting a catalog on the wrong business or number will remove products from a WhatsApp line you did not intend to touch.
5. If a catalog is already connected, click **Disconnect**.
Wait for the confirmation banner **Catalogue successfully disconnected** and the empty state.
Keep this tab open — you will return to it in Step 3.
## Step 2: Enable the product catalog from bitbybit Commerce
1. Open [Commerce → Products](https://app.bitbybit.studio/commerce/products).
2. Toggle the **WhatsApp Catalog** switch **ON** for one product to start.
3. Confirm any prompts to activate the catalog.
Enabling the toggle creates a catalog in your Meta Business Account named **`bbb - `** (for example, `bbb - 1646`). A green **Catalog active** banner appears once the catalog is provisioned in Meta.
## Step 3: Link the bitbybit catalog in WhatsApp Manager
1. Open [WhatsApp Manager → Catalogue](https://business.facebook.com/latest/whatsapp_manager/catalog). Confirm the business (top right) and the phone number in the Catalogue card still match the bitbybit-connected account before continuing.
2. Click **Connect a catalogue** (or **Choose a Catalogue** from the empty state).
3. In the picker, search for **`bbb - `** and select the match. This is the catalog bitbybit created in Step 2.
4. Confirm the connection.
## Step 4: Verify the sync
1. Return to [Commerce → Products](https://app.bitbybit.studio/commerce/products).
2. Confirm that products with the **WhatsApp Catalog** toggle ON appear in the catalog under WhatsApp Manager.
3. Wait a few minutes — Meta reviews each item before it becomes visible in WhatsApp. Products stay in **Pending** until they move to **Published**.
Once the link is in place, toggling a product on or off in bitbybit Commerce updates its availability in your WhatsApp catalog automatically — no further WhatsApp Manager steps are needed.
## Important notes
* **The link is one-way.** Products created directly in Meta Catalogue Manager do not sync back to bitbybit Commerce. Manage your catalog from bitbybit to avoid drift.
* **Approval delay is normal.** Meta usually publishes products within a few minutes. If a product stays **Pending** for hours, open it in Catalogue Manager to check for rejection reasons.
* **One catalog per phone number.** WhatsApp allows only one catalog per number. Disconnecting in Step 1 is required before linking the bitbybit catalog.
* **Keep the MBA connected.** If your Meta Business Account is unlinked from bitbybit, the sync stops and the toggle in Commerce becomes unavailable.
