When creating Item list file, please make sure the following rules:

Don't remove the header name. Don't enclose the header name with " " (double quotation marks)

You can't remove the header name on the Item list file. For the unnecessary item, enter the header name on the first row and leave other rows as blank. Don't enclose the header name with " " (double quotation marks).

Don't create multiple rows for the same Item ID。

If multiple rows exist for one Item ID, we cannot guarantee which row will be applied in the ad displayed.。

Even if the item is displayed in the ad, it may not be displayed depending on the display format of the ad.

Some part of ad creatives may be displayed.

Item names and item descriptions may be displayed partially on the ads.

Change URL when changing the image (the old image is cached).

When changing the image file on updating Item list, update the image URL itself. If you replace the image with the same image URL, the older image may be displayed on the ad.

When multiple prices are in the Item list, the formatted sale price is used. The following order shows which price appears.

1. Formatted Sale Price (most prioritized)

2. Sale Price
3. Formatted Price
4. Price
If prefix or suffix is not set for the "Sale Price" and "Price," the price will not show on the ad.
*We recommend not to use "Sale Price" and "Price" when using "Formatted Sale Price" and "Formatted Price" and contrariwise.

When changing (updating) the item list the timing to take effect varies between items.

When changing multiple items the former item and the changed item may be displayed in one ad. "Display setting" and "Stock information" are changed with priority.
