1. Introduction – How to manage your Boulanger stock feed on Lengow

This guide explains how to configure and manage your Boulanger feed. Before starting to set the parameters for your feed, please note the following recommendations.

Here are the steps you need to follow to advertise your products and to retrieve your Boulanger orders:

  • Contact Boulanger (Johanna Dendievel / ou Nicolas Ferret / to know if you are eligible to sell your products on their website.
  • Ask Boulanger for the creation of your online shop on Mirakl (this is essential if your products are to be advertised).
  • Ask for Boulanger feed(s) creation in Lengow.
  • Separate out the products that you don’t want to advertise or that don’t belong in your chosen Boulanger category.
  • Complete the "Field Matching" in order to match your source feed fields with the existing Boulanger fields.
  • Change the values of your feed source by using Automatic Rules and/or Search-Replace to adapt them to Boulanger’s expectations.
  • Organise your categories so that they correspond with the Boulanger categories.
  • Set up the options for tracking your stock (indexing frequency, alerts etc.).
  • Fill in your API username and password to launch the distribution of your products.
  • Manage your orders.

All these actions are detailed below.

2. Boulanger categories

2.1 In which categories do your products belong? 

Boulanger works by categories. Each category has its own structure and corresponds to a specific type of product. For example, it is impossible to sell headphones within the "Petit ménager" (household appliances) category. 

To know which category is most suitable for your products, contact your Boulanger account manager (this is often defined when you sign your contract with Boulanger).

Once you have this information, ask for the corresponding feeds in Lengow.

2.2 Open your Boulanger data feeds in Lengow

​Each Boulanger category requires the creation of a new feed in Lengow

Search for the title "Boulanger" so that you can see all the available categories.

Or, look in the "Marketplaces" section, "French" flag in and then select the Boulanger feed(s) you need.

In Lengow, you will have the same number of feeds as Boulanger categories needed for the distribution of your products. Each Boulanger feed is independent of the others and, even though there are similarities, each one needs to be set up separately.

Now let’s see how to set up one of them.

3. Set up your Boulanger feed

Boulanger 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 Boulanger:

  • 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 Boulanger category.
  • The "parent products", if your source feed contains any

3.2 Match the fields

Boulanger 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)"). You will find here a file for each category. 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

Boulanger does not manage product variations. A separate product file will be created for each product variation featured in your source feed.
Example : Boulanger will publish several sheets on its website for a headphone available in different colours :

  • One product sheet for the product X in black
  • One product sheet for the product X in grey
  • One product sheet for the product X in red
  • One product sheet for the product X in blue
  • One product sheet for the product X in green

You therefore need to filter your "parent products" if your source feed contains any.

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 Boulanger. 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 lists of valid attributes available in the appendix to know the values accepted by Boulanger for each attribute (See here how to read the file).

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

NOTE :  A "Variations" tab is available in "Feed Management". This "Variations" tab is aimed to help you fill in the "MARQUE" field. Proceed as follows:

In "Feed Management" > "Field Matching", match the field "MARQUE" with the corresponding field from your source feed .

Then, in "Feed Management" > "Variations", carry out the correspondence between the brands contained in your source feed and those accepted by Boulanger.

Brands that you match in the"Variations" tab will be send within the "MARQUE" field of your optimised feed.

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

3.5 Set up your special offers / sales

3.5.1 Promotions

To configure your special offers on Boulanger, fill in the following fields :

  • "price" : this field must contain your strikethrough price
  • "discount_price" : this field must contain your promotional price
  • "discount_start_date" (optional) : this field must contain the start date of the promotion (YYYY-MM-DD format)
  • "discount_end_date" (optional) : this field must contain the end date of the promotion (YYYY-MM-DD fomat)

3.5.2 Sales

To configure your sales on Boulanger, follow our guide.

3.5.3 Special offers

To take part to the Black Friday event, follow the same configuration as for the promotions above. Please ensure that you fill in the "discount_start_date" and "discount_end_date" fields and that your updated offers will be sent the day before the event.

3.6 Configure your shipping costs

The shipping costs and delivery methods are defined by Boulanger. Contact your Boulanger account manager to obtain more details on this.  

3.6.1 Delivery methods

The choice of delivery methods has to be made in your Mirakl back office. You will have the choice between:


3.6.2 Shipping costs

Please note that each product corresponds to a logistics category. The prices are calculated according to:

  • the logistics category associated with the product 
  • the delivery method associated with the product 

For the logistics category, several options are possible. You can either:

  • Keep the default logistics category attributed by Boulanger to your products. In that case, no action on your part is necessary. Contact your Boulanger account manager if you want to receive more details on this.  


  • Modify the default logistics category attributed by Boulanger. In this case, follow the following steps: 

1 / Add a virtual field "Boulanger_logistic_class" by going to in "Feed Management" > "Source feed" tab :

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

3 /  Create one (or more) automatic rules to fill in the virtual field "Boulanger_logistic_class" with your chosen value (ask Boulanger to provide you with details on the logistics classes available). You will find below some examples of automatic rules you could create :

Example 1 : Automatic rule with a condition on the field "Identifiant_unique"

Example 2 : Automatic rule with a condition on the field "Catégorie"


  • Set up free shipping costs for your products. In that case, follow the process explained above and create an automatic rule in which you will indicate THEN "Boulanger_logistic_class" becomes XXS. Shipping costs are set to 0,00€ for all delivery methods of this logistics class XXS.

3.7 Category mapping

In order to categorise your products on Boulanger, use the Boulanger taxonomy so that your categories match those of the Boulanger marketplace. To carry out this mapping, go to the tab "Product Management":

  • Open the Boulanger taxonomy
  • Search for your category in the taxonomy (press "Ctrl+F" to search for your desired key word)
  • Click on the corresponding line
  • Click on "SAVE"

 Don’t forget to click on "SAVE" once you have carried out this operation.

3.8 The options tab

In the "Options" tab of your Boulanger feed, check the various points and modify them if needed. For more details about this tab, consult our tutorial "Options tab".

3.9 Check the attributes in your optimised feed

To check the data sent to Boulanger, consult the optimised feed. All the updates you make in Lengow are visible IMMEDIATELY (automatic rules, search/replace, matching etc.) in the optimised feed.

Comment: Check your optimised feed as often as possible to make sure that your parameters have been correctly applied to your new products.

4. Integration of your catalogue on the Boulanger site

If the data in your optimised feed is adequate and complies with the Boulanger requirements, you can send your products to Boulanger. To do this, you must:

  • Check that there are no rules in your backoffice Mirakl Boulanger
  • Enter the API username and password in Lengow
  • Consult the integration reports

Just to remind you, your Boulanger vendor shop must be created in order to advertise your products on Boulanger. Contact your Boulanger account manager if you need help on this.

4.1 Mirakl configuration assistant

If you have created rules with the help of the configuration assistant in your Mirakl Boulanger interface, your special offers and products feeds may be blocked and they might not be sent. To avoid this problem, no rules must be present in your Mirakl Boulanger.

If all of your products are set up via Lengow, delete them (in case of doubt, contact your Boulanger account manager) 

4.2 Enter the API IDs

You must enter your API IDs in Lengow in order to be able to send your product catalogue to Boulanger. To do this, you need to go to "Feed Management" > "API login" tab :

  • Mirakl_key : Enter your API key here. To get it, log in to your Boulanger Mirakl interface, click on your email address in the upper right ("My account") and then on "API key". If your API key has changed, you also need to change it in your Lengow account. Here is an example of an API key: b36a2665-109a-4135-a0f0-460d70568ca4.
  • Mirakl_storeid : Enter your Mirakl reference here. To find it, connect to your Mirakl Boulanger interface and click on "Boutique" > "Paramètres" (visible at the top of the page: identifiant: XXXX)

Remember to save by clicking on "APPLY".

4.3 Sending/uploading your product catalogue

Two distinct feeds are sent to Boulanger:

  • Products feed: it enables the integration and creation of your products. It is sent to Boulanger once a day around 4.00 am. If your products are free from errors, they will be created in Boulanger and appear online within 48 hours, after the product feeds are sent.
  • Offers feed: it enables the update of prices, stock etc. It is sent to Boulanger every 4 hours. When the offers feed is received by Boulanger and if your products are free from errors, your datas will be updated almost immediately on Boulanger website. 

4.4 Products and offers integration reports 

Products and offers integration reports allow you to check that your products (products feed) and updates (offers feed) have been correctly integrated into the Boulanger site.

These reports only contain the products of your catalogue that have been rejected by Boulanger. For each of your products that has an error, Boulanger specifies the reason for the rejection.

Note: If all of your products have been correctly integrated and updated, all your products will appear in the report without the column "errors".

Note 2:  If the integration report is empty, it means it is not available yet.

Integration reports for products and offers are available and could be downloaded :

  • Within Lengow in "Feed Management" > "Indexing history" tab > click on the blue link "Report"
    • Products feed report : Type = "products_mirakl"
    • Offers feed report : Type = "offers_mirakl"

  • Within your Boulanger Mirakl backoffice. Here is the path to follow to download these reports :
    • Offers feed report : "Mon stock" > "Importer des offres par fichier" > "suivi d'import des offres"
    • Products feed report : "Mon stock" > "Importer des offres par fichier" > "suivi d'import des produits"

5. Stop advertising a product

5.1 Set a quantity 0

Lengow can only update the products that are present in your source feed.

In order to deactivate, i.e. stop selling, a product that is online on the Boulanger site, set the quantity to "0" in Lengow (for example, either by using an Automatic Rule or in the product file).

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

By default, Boulanger 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. However, in order to avoid problems of over selling, make sure to keep the out of stock products in your source feed for 1 to 2 days with the quantity set to 0. This will ensure that the information about the product being unavailable is sent to Boulanger.

5.2 Delete an offer

You can delete one or more offer of your Mirakl Boulanger back office directly from Lengow. To do this, you must use the field "update_delete" and put the attribute "delete" in this field. This will ensure that the product is removed from Boulanger website. Here is how you should proceed :

1 / Create a virtual field "Boulanger_update_delete" in "Feed Management" > "Source feed" tab :

2 / Match this field 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 as follow (The example given is for product 12 of the product catalogue. Make sure to change it according to your data and needs):

The "delete" information will be automatically included in the optimised feed sent to Boulanger. 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.

Remove any matches in the "Merchant Fields" column of the "update-delete" field, if you had previously set one up.

6. Order management

6.1 Order retrieval times 

Lengow retrieves orders made on Boulanger website once an hour.  

6.2 Order processing

1 / When a new order is placed on Boulanger, it appears in Lengow in the "New Order" tab. At this stage, you can either:

Accept the order: it will then appears as waiting for shipment ("Orders waiting for shipment" tab)

Note:  It is possible to automate this step by automatically accepting orders. To do this, go to the "Order Management" tab >  "Orders automation" tab > tick the box "Boulanger" :

Save by clicking on "Save Settings".

When activating this option, you must be certain that you will be able to honour all your orders.

Refuse the order: it will be automatically referred back to Boulanger as a cancelled order. This order does not need to be dealt with; the client will be notified by Boulanger that his/her command has been cancelled.

2 / When your order appears in the "Orders waiting for shipment" tab, you must prepare the order and send it to the customer. When you are ready to send the order, fill in the carrier’s details and the tracking number of the package and confirm the shipping. The order will then show in the "Orders Sent" tab.

Note: If you are using one of our modules or our web-service to import orders into your e-commerce back office, you can import the order into your back office from the "SHIPPING" status ("Orders waiting for shipment" tab). When you have deal with the order and confirmed the expedition in your back office, the order will appear automatically in the "Orders Sent" tab in Lengow.

3 / Once your order is in the "Orders Sent" tab, we inform Boulanger that the order has been sent to the customer. Boulanger then informs the customer that the order has been sent.

6.3 Cancellation of an order
