Jardiland / Gamm vert allows EAN matching, i.e. if your products have already been created by the marketplace by another reseller, you don't need to send the "products" values usually required to create the product ad on this channel.
- "Gencode" field must be matched with the "EAN" code of the product.
- Select the "Unique_Identifier" value to fill in the "Product_ID_Type" attribute.
"Unique_identifier" refers to EAN here.
