<table><thead><tr><th width="175.19140625">Data</th><th width="226.4921875">Description</th><th width="340.6015625">Notes</th></tr></thead><tbody><tr><td>ProductId</td><td>The Shopify Product ID of the event item </td><td></td></tr><tr><td>VariantId</td><td>The Shopify Variant ID of the event item </td><td>This value is only present when there is a variant selected for the saved item</td></tr><tr><td>ItemID</td><td>Either the VariantId if present, or the ProductId if no variant is selected</td><td>The ItemID ensures that the most accurate product data is loaded. Where no variant has been selected for the saved item, the ProductId is used</td></tr><tr><td>LatestWishlistItems</td><td>Up to 10 ItemID's of the customers most recently saved items</td><td>This data can be referenced to display a users most recently saved items within a flow</td></tr></tbody></table>

You can use Klaviyo's **catalog lookup tag references** to add dynamic product information such as descriptions, prices and product images in your Wishlist  emails or SMS templates.

Please see [this](http://help.klaviyo.com/hc/en-us/articles/360004785571) Klaviyo help article further information on catalog lookup tag references.

The Swish x Klaviyo integration uses three different template's, depending on the data source and the email type.
