# Multi Product

{% hint style="info" %}
This feature is available on the **WhatsApp channel only**.
{% endhint %}

The *Multi Product* node is used to present items to customers from a catalog you've set up in Facebook Business Manager. Customers can then add selected items to a cart and submit the order to your business. 

You can display up to a maximum of **30** products from your catalog to the customer at a time *(a limitation enforced by Meta)*. You can use the *Multi-Product* node **multiple** times in a flow, as long as all the products they refer to are from the same catalog.

## Linking a product catalog to Chat Flow

1. [Set up your catalog](https://www.facebook.com/business/help/1275400645914358?id=725943027795860) in the Facebook Business Manager Commerce Platform and upload the inventory to the catalog.
2. Add a *Multi Product* node to your workflow at the desired place.
3. Add the *Catalogue ID* to the node. 
   * This ID is created when you add the catalog to Facebook Business Manager.
4. Add *Product IDs* to reference the specific products from the catalog. This can be added in two different ways:
   * **Dynamic:** The flow-builder can use an API call to fetch the product IDs from your management system before using the *Multi-Product* node and use these IDs as variables in Chat Flow
   * **Predefined:** The flow-builder can manually add the product IDs to the node (i.e., "hard-coded").
