Creating a Product Feed

A product feed is a reusable, named set of rules that picks products automatically at send time, shared across broadcasts. Save a condition such as "best sellers with at least 10 in stock and under 5,000 yen" once, and every broadcast that selects the feed from a product card shows the latest matching products automatically. This article covers how to create a product feed and what each setting does.

What is a product feed?

A product feed is a reusable set of conditions that picks the products for a product card automatically on every send.

You combine "what products customers see first" (best sellers, newest, and so on) with filters (collection, inventory, price, and so on), save it, and select it as the data source of a product card. When you update the feed, every send that uses it picks up the change.

To use product feeds, the Lumo app must be installed on your Shopify store and product data must be synced.

Creating a product feed

Create product feeds from "Product feeds" under "Broadcasts" in the menu.

1. Open "Product feeds" under "Broadcasts" in the menu
2. Click "Create feed"
3. Set the "Feed name" and the "LINE official account" (the account for the target store)
4. Choose how products are selected under "What products should customers see first?"
5. Configure "Filters" and the fallback as needed
6. Check the products under "Preview", then save

You can also create one on the spot from "Create a new feed" on the product card editing screen, with the same settings.

Product selection types

"What products should customers see first?" determines which products the feed prioritizes.

For "Best sellers", you can adjust the sales window with "Aggregation window (days)", from 1 to 365 days.

Setting filters

Filters narrow the feed down to products that match your conditions. When multiple filters are set, only products matching all of them (AND) are included.

You can set one condition per filter field. Tags and collections accept multiple comma-separated values.

Setting the fallback

The fallback decides what to show when no products can be fetched (no sales data, no browsing history for the recipient, and so on).

For personalized types such as "Recently viewed", some customers will always have little browsing history, so we recommend configuring a fallback.

Checking with the preview

On the feed creation and editing screen, you can preview the products that will be selected before saving.

Click "Refresh preview" to see the products selected under the current conditions. If fallback products are being shown, a message says so. For "Recently viewed", you can enter a LINE user ID to preview from a specific customer's perspective.

Using it in product cards and broadcasts

Use a saved product feed as the data source of a product card.

1. Create a "Products" card in Card Type Messages (or use "Create a new product card" on the broadcast screen)
2. Choose "From a product feed (auto)" as the data source and select the feed
3. Select that product card in a broadcast or auto message

The "In use" column in the feed list shows how many broadcasts, messages, and cards reference each feed.

What happens when a feed is deleted

Deleting a feed does not break scheduled broadcasts.

Product cards and broadcasts that referenced the deleted feed fall back to a standard product selection (such as best sellers) instead of the feed's conditions, and the send continues. Before deleting, we recommend checking the reference count in the "In use" column of the list.
