The product/EAN code is not existing yet on Kaufland.

To make sure the product/EAN code will be sold on Kaufland, you will need to add the product with all its content yourself. At this moment our Kaufland WooCommerce plugin doesn’t support this feature yet. For this reason, we advise you to follow the following steps:

After the product is published on Kaufland, you can connect the WooCommerce product with the Kaufland product by publishing the product from WooCommerce again via bulk actions.

{"message":"Product not found","errors":[]}

This means the product's EAN doesn't exist in Kaufland's catalog yet. Before you can publish an offer (price/stock) from WooCommerce, the product itself must first exist in Kaufland's product database.

Here's what to check:

The internal reference is required and cannot be empty

The internal reference field is empty

In the Kaufland plugin settings, check the Internal reference source option and choose a field. For example: the easiest one you can choose is Product ID.
