# Send a WhatsApp catalog product in an open chat

> Send one WhatsApp catalog product, or the whole catalog, inside an open customer service window. Standard and Premium only.

Catalog and product messages go out through Live Chat, and only inside the 24-hour customer service window. Catalogs are on Standard and Premium. The assistant sends them only after you ask.

## Ask this

```text theme={null}
List products in my catalog. In the open chat with +14155550123, send the product whose retailer id is SKU-104. Add the body "This is the one you asked about." If the chat window is closed, stop.
```

## What the assistant calls

**1. Find the product**

`list_catalogs` and `list_catalog_products` identify the catalog and the `productRetailerId`. The assistant does not invent a product id.

**2. Send inside the window**

`send_product_message` takes the conversation `id` and `productRetailerId`. Optional fields are `catalogId`, `body`, and `footer`. `send_catalog_message` sends the connected catalog instead of one product, and it needs `id` and `body`.

`send_product_list` and `send_product_carousel` cover several products in one message. A product that is not in the catalog yet is [Add a catalog product](https://docs.greentick.ai/mcp/use-cases/add-catalog-product.md). Field limits are on [Inbox](https://docs.greentick.ai/mcp/inbox.md) and [Catalogs and ads](https://docs.greentick.ai/mcp/catalogs.md).
