2.Open your data feeds in Lengow

Ask for the creation of a new feed in Lengow

Search for the title "Carrefour ES" and select it.

Or, look in the "Marketplaces" section, "Spanish" flag in and then select the Carrefour ES feed.

Now let’s see how to set up a Carrefour ES feed.

3. Set up your feed asks merchants to use specific attributes in order to reference the products on their marketplace. You therefore need to adapt attribute values from your source feed in Lengow.

3.1 Creating a feed segmentation

Before starting to change your attributes, first you need to filter your products so that you don’t send to

  • The products that you do not wish to sell in this marketplace.
  • The products in your feed that don’t match the type of products normally found in the category.
  • The "parent products", if your source feed contains any

3.2 Match the fields requires a particular feed structure depending on the category chosen.
In order to proceed with the field matching, you need to go to the page "Feed Management" then "Field matching".

Check the field matching and complete any missing information. Read the field definitions carefully and there you will find:

  • The field name.
  • The field definition.
  • An example, if there is one.
  • Whether the field is required or optional. A "required" field has to be filled in so that the product can be created or updated.
  • Whether it is a free text field or whether specific attributes are required. If specific attributes are required, you will see the following message: "Des valeurs sont imposées pour ce champ (liste disponible dans notre guide diffuseur)" (= "Attributes are required in this field (list available in our distributors guide)"). Consult the valid values for If you are using a field that requires valid attributes, it is compulsory to change the attributes in your source feed. If these attributes are not in your source feed, you must change them using search/replace or automatic rules (See here how to read this file).
  •  If the field is used to create your products (Product data: this is then shown as "Champ du flux produit") or to update them (Special offer information: this is not shown as "Champ du flux produit").

3.3 Set up product variations

Carrefour ES accepts size and/or colour product variations.

To manage your variations, fill in the following fields:

  • parentSKU: parent EAN (a common EAN code for all the variations of a product). This field must be empty if your product does not have variations.

​Note: If your catalog does not contain parent EAN values for your products, contact our support team.

  • colorMP: product colour. This data is mandatory if the product is available in different colours.

  • sizeMP: product size. This data is mandatory if the product is available in different sizes.

A "Variations" tab is available in "Feed Management". This "Variations" tab is aimed to help you fill in the attributes "Size" and "Color".

To complete your products' attribute values, proceed as follows:

  • In "Feed Management" > "Field Matching", match the field "sizeMP"  with the corresponding field from your source feed.
  • Then, in "Feed Management" > "Variations", carry out with the mapping between the values contained in your source feed and those accepted by

Note: If a size is missing in the drop-down menu, please contact your account manager and ask him to create the concerned brand.

3.4 Enter attribute values for your products

The majority of attributes are optional but it is recommended to fill in a maximum of attributes so that your product sheets can be the most complete possible and then more attractive.

The attribute values can be free (free text) or defined by If specific values are required, you will see the following message "Des valeurs sont imposées pour ce champ (liste disponible dans notre guide diffuseur)" in the field definition in the "Field Matching" tab. In that case, refer to the list of valid values accepted by for each attribute (See here how to read this file).

If values from your source feed do not correspond to the ones expected by you must adapt them by using Search-Replaces and/or Automatic Rules.

NOTE : If the product is no longer sent to, without having set the quantity to "0", the offer will remain visible on and the latest stock information available to will be displayed.

By default, works by updating data rather than by overwriting it.   

Lengow has put in place a security system that allows you to keep your products visible "virtually" when they have disappeared from your source feed. They are kept in the category "virtual products", in the "Product Management" tab.

1 / Create a virtual field "Carrefour_update_delete" in "Feed Management" > "Source feed" tab.

2 / Match this virtual field "Carrefour_update_delete" with the field "update_delete" in "Feed Management" > "Field matching" tab. Save by clicking on "Save Modifications" at the bottom of the page.

3 / Create an automatic rule and fill in the "Carrefour.es_update_delete" field the value "delete".

The "delete" information will be automatically included in the optimised feed sent to The products will then disappear from your Mirakl backoffice > "suivi des offres".

Note: To delete your entire catalogue, go to "Feed Management" > "Field matching" and enter the value "delete" in the "Personalized Field" column of the "update_delete" field.
