Frequently asked questions#

• Is ITEM_ID used for pairing products into product cards?
  • No, it is not. Pairing uses the product name and category. More information is available in the article Complete Guide to Product Pairing on Heureka Using Mergado.
• Can ITEM_ID be duplicated in the feed, i.e. the same value for multiple products?
  • No. ITEM_ID must be unique for every product, so that Heureka can correctly identify the product within the Verified by Customers service or in the availability feed, where ITEM_ID is used as the unique identifier.
  • Instructions for finding and hiding products with duplicate ITEM_ID values are described in the guide How to find duplicate values.
• What if ITEM_ID is missing from my feed — can I fix this in Mergado?
  • Yes. Using the Rewrite rule, you can populate the ITEM_ID element with the Mergado system variable @MERGADO_ID, which contains a unique number for every product. This gives you unique values for each ITEM_ID.
  • You can also use the pre-built automation named ITEM_ID from MERGADO_ID, which you simply run.
  • Other options: hide products with a missing ITEM_ID using the Hide product rule, or import values into ITEM_ID using the Data file import rule.
• What is the difference between ITEM_ID and ITEMGROUP_ID?
  • ITEM_ID must be unique for every product, whereas values in ITEMGROUP_ID can be the same (duplicated) for variants of the same product. ITEMGROUP_ID is the shared identifier for product variants.
• How do I filter products with specific ITEM_ID values?
  • Create a query on the Products page in Mergado for the ITEM_ID element values using the enumeration condition — is contained in the enumeration.
