When trying to update the EAN (European Article Number), which contains the barcode information for a SKU, you may face issues with catalog synchronization between the VTEX Admin and API. This can impact inventory management and customer experience.

To solve this issue, consider deleting the SKU EAN and then adding a new EAN.

To update the current SKU EAN, you must first delete all the EAN values associated with the SKU.

• Delete SKU EAN: Use the endpoint to delete a specific EAN.
• Delete all SKU EAN values: Use the endpoint to delete all the EANs associated with the SKU.

Step 1 - Add a new EAN to the SKU

Only after all previous EANs have been deleted can you add a new EAN to the SKU. To do this, use the Create SKU EAN endpoint to create the new EAN value.

Step 2 - Check whether the SKU EAN has been updated

After adding the new EAN, use the Get SKU by EAN endpoint to confirm it has been updated. The new EAN values will be displayed in the AlternateIdValues array.

"AlternateIdValues":
[
"8781",
"878181"
]
