Marketplace-specific requirements and exceptions

Setup

On ChannelEngine

Leroy Merlin is a Mirakl-based marketplace, so you can connect it to ChannelEngine using a Mirakl Connect SSO account. For more information on this, check out the Mirakl-based channels: SSO authorization article.

As Leroy Merlin does not support repricing, you can leave the Mirakl seller name field empty.

Leroy Merlin uses the following sales channels, which need to be activated by your account manager at Leroy Merlin before they are visible on ChannelEngine:

• 001 LM FR/BELGIQUE/CORSE - Leroy Merlin France
• 002 LM ES - Leroy Merlin Spain
• 003 LM PT Leroy Merlin Portugal
• 005 LM IT - Leroy Merlin Italy
• 006 LM PL - Leroy Merlin Poland
• 026 - Leroy Merlin Romania
• 014 BM FR - Bricoman France

For more information on sales channels, check out the article Mirakl-based channels: setting up sales channels.

Invoice uploads

To configure your invoice settings, go to Advanced settings. Then, select one option from the dropdown menu in the Enable invoice uploading field, which contains the following options:

• ChannelEngine invoices - when ChannelEngine receives a shipment, ChannelEngine automatically generates an invoice and attaches it to the shipment before exporting the shipment.
• Merchant invoices (optional) - when ChannelEngine receives a shipment, ChannelEngine exports the shipment – even if there is no invoice attached to it.
• Merchant invoices (required) - when ChannelEngine receives a shipment, ChannelEngine only exports the shipment if an invoice is attached to it. If not, you receive a notification.
• None - when ChannelEngine receives a shipment, ChannelEngine takes no action other than notifying you that no invoice is present.

If you select one of the Merchant invoices options, make sure to upload the invoice to ChannelEngine via the Merchant API or via the web interface. To learn more, check out the article ChannelEngine: upload merchant invoices.

Categorization

Categorization is mandatory if you want to create or update existing product information on Leroy Merlin. Both categorizations and mappings only result in updates if the content connection is enabled, and the relevant credentials have been entered. (See the Setup section below.)

All categories are listed on Leroy Merlin in English, and they may differ from the categories shown in the Leroy Merlin front-end. Make sure to map as many attributes as possible so your products are displayed prominently.

For Leroy Merlin Romania, map the following category for WEEE (Waste Electrical and Electronic Equipment) products: EPR (Extended Producer Responsibility).

Mappings

Mapping per sales channel

Some attribute names in the Mapping page are preceded by the country code of the sales channel in which the attribute appears. To understand which country codes appear in the Mappings page, check out the section on country codes per sales channel. 

Content

Products must be validated by an operator before they can be linked to an offer. If not, the offer displays the error "The product doesn't exist".

All products (required)

• Product identifier - the product's 13-digit EAN or GTIN.
• Brand - the product's brand. If your brand is not listed, contact Leroy Merlin so they can add it. In the meantime, use Autre (Other).

The following required attribute is common to all Mirakl-based marketplaces:

• Export strategy - choose a strategy for exporting product data. You can select from the following export strategies:
  • Yes - export all product content to the marketplace, including the EAN (GTIN), category, and other mapped attributes. This option is ideal if you manage both product content and offers through ChannelEngine for the marketplace. Before you set this option, ensure that you map all required attributes.

  • No - do not export product content to the marketplace. Choose this option to keep the product content excluded from exports and only export the offers. This option is ideal if you do not want to export the product content yet, or you want to export only the product offers because the product content already exists on the marketplace.
     

    NB: the default export strategy is Yes, even if the Export strategy attribute is left unmapped.

All products (optional)

• Code for internal use - the product's SKU or Merchant product number.
• Energy-related product label [country code] - the product's energy efficiency label.
• Existing product LM - used by Leroy Merlin to indicate if the product already exists in their database. Not to be mapped.
• Image large 1-10 - the product's image URLs. The minimum resolution supported is 500x500 px and the maximum file size is 10 MB. If possible, the images should have no text.

E.g.: A French title cannot be chosen without Image large 1 and Long description FR.
• Security data sheet [country code] - packaging rear - the product's security data sheet, in the respective language.
• Technical document FR B2B - the URL of the product's technical data sheet.

All products (required)

• Price - the product's price.
• EAN - the product's 13-digit EAN or GTIN.

All products (optional)

Below are key optional offer attributes and their descriptions.

The following offer attributes are common to some Mirakl-based marketplaces:

• ECO #1-5 amount - the amount due for the eco-contribution related to the product. E.g.: 2.50.
• ECO #1-5 EPR category code - the extended producer responsibility (EPR) code that applies to the product.

E.g.: DE-WEEE, FR-DEA, etc.
• ECO #1-5 producer ID - your producer ID, received upon registering with a packaging register, such as Germany's LUCID. The maximum number of characters is 255.

If pricing v2 is activated in your environment, you will see the following offer attributes, which are common to all Mirakl-based marketplaces:

• Allow promotion below min price - set it to ‘true’ to allow the promotion price to drop below your product's minimum price. To learn more, check out the article ChannelEngine: promotions.
• Strike price - the regular selling price. Use it in combination with the Price attribute to set up a discount/strikethrough pricing. To learn more, check out the 'Working with discounts' section of this article. 
• Additionally, the Fee groups attribute appears in Mappings, Fee group mappings, if pricing v2 is activated. Map the marketplace fee group ID of the product there.  

The following offer attributes are also common to all Mirakl-based marketplaces:

• Discount start date - the date from which the product's sale price is valid, if applicable. Input the date as a fixed value. The date format is YYYY-MM-DD HH:MM:SS ZZ. All dates follow American month-day formatting, and all times follow 24-hour formatting in the UTC timezone. E.g.: 2026-10-25 15:30:00 +01 will start your discount on 25 October 2026 at 3:30 PM, one hour ahead of UTC time.
• Discount end date - the date until which the product's sale price is valid, if applicable. Input the date as a fixed value. The date format is YYYY-MM-DD HH:MM:SS ZZ. All dates follow American month-day formatting, and all times follow 24-hour formatting in the UTC timezone. E.g.: 2026-10-30 23:59:59 +01 will end your discount on 30 October 2026 at 11:59 PM and 59 seconds, one hour ahead of UTC time.
• Discount price - the product's sale price, if applicable. This attribute must have a lower value than the Price attribute. This attribute only applies if you use pricing v1.
• Discount quantity threshold - the minimum quantity required for the discount rate to be available.
• Leadtime to shipment - the number of days before you ship the product. By default, this is set to two. You can create your own unique rules, if applicable. For more information on this, check out the article Lead time to ship in Mirakl's help center.
• Minimum quantity alert - map this attribute to receive a notification from Mirakl if your stock drops below the threshold defined.
• Offer state - the product's condition. Find your option from the dropdown menu by selecting the fixed value to apply to all.
• Product tax code - the taxation code applicable to the product.
• Logistic class - your optional shipping class. Make sure to map the shipping class using the marketplace’s codes and not with the labels that are visible in the partner portal's user interface. These codes vary per marketplace. If this marketplace makes use of logistic class codes, they can be found below.

Logistic class codes

Carrier

Carrier mapping is not required on Mirakl-based marketplaces. However, with carrier mapping, you can map your carrier to a specific list of carriers maintained by this marketplace. Carrier mapping enables ChannelEngine to automatically send the tracking codes to this marketplace, allowing buyers to eventually track the shipment themselves. If your carrier is missing from the list, please directly contact the marketplace.

Pricing

Leroy Merlin requires the prices to be submitted in EUR, PLN, or RON. If you do not have pricing attributes in the required currency, you need to set a currency conversion.

Working with discounts

Pricing v1

• To set up a discount, map the Discount price, Discount start date, and Discount end date attributes. If you want to set a permanent discount, map the Discount end date attribute with a date in the far future instead of leaving it unmapped. Otherwise, the offer is not exported, and errors are shown on the Validation and feedback tab.
• The discounted price is only exported if it is lower than the base price.
• If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped.
• To set a bulk discount, the Discount quantity threshold must be set to a value higher than 1. For example, a value of 2 indicates that the buyer must purchase two or more products at the same time to benefit from the discount.

Pricing v2

• To set up a discount, in the Offer mappings step, map the Strike price attribute to your regular price. Then, map the Discount start date and Discount end date attributes to indicate the start and end dates of your discount.
• If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped. To learn how to set up a bulk discount, check out Bulk discounts.
• In the Pricing step, go to Price rules. Map the Price attribute to the discounted price. Both Min. price and Base price fields must be mapped. Note that ChannelEngine exports the higher of the two values – typically the Base price. To learn more, check out ChannelEngine: price rules v2.
• The Price and Strike price attributes cannot be mapped with the same value. ChannelEngine only sets a discount if the value in Price (Base price) is lower than the value in Strike price.
• If set up correctly, your product displays a discount label and a strikethrough price on the channel.

Listed products

If you have problems with products not appearing on Mirakl-based marketplaces – especially if you are trying to create products, check the Listed products page for more information. Use the Channel status filter or the Validation and feedback tab to view all known errors for specific products.

If you see either of the below statuses, refer to the article ChannelEngine: why is my product listed as 'Product not found' in the inventory report?:

• Product not found in inventory report
• Product not in offer file

Products that ChannelEngine has failed to export are shown as Invalid, e.g.: products with an empty GTIN or that do not yet exist on the marketplace.

Alternatively, download the error report generated by Mirakl. To do so:

1. Log onto the Mirakl platform and go to Catalog, Product imports.
2. Identify the latest report and click the See details button.
3. Download the CSV file Non-integrated products report.

FAQs

I cannot find Leroy Merlin when selecting the marketplace during the SSO setup. What should I choose?
Within Mirakl, Leroy Merlin is identified as Marketplace Adeo – its parent company. Therefore, select Marketplace Adeo when prompted.

I see duplicate attributes, but ChannelEngine does not map them automatically. What should I do?
Although those attributes look like duplicates, they have different IDs. That is why ChannelEngine cannot map them automatically, which means you need to map them twice.

My products are exported successfully, but they are not created on Leroy Merlin. What is happening?
The three most common reasons for products that fail to be created on Leroy Merlin are:

1. You have set up a mapping configuration in the Leroy Merlin back-end, which prevents the automatic content creation done by ChannelEngine.
2. The Product tag for XML file imports, found in the Leroy Merlin back-end under My account, Settings, Imports, must be set to Product.
3. The use of special characters in attributes such as Description longue can also make the import fail. If you use tabs (|) as separators, for instance, make sure to do so consistently. Spaces cannot be used as separators.

How can I delete my products on Leroy Merlin?
Although it is possible to delete offers, it is not possible to delete products on Leroy Merlin.

How often does each task run on Mirakl-based marketplaces?
By default, Mirakl-based marketplaces follow the schedule below:

When I click the View on Leroy Merlin button on the Product details page, a link to the French website opens. Why is that?
When you sell a product across multiple sales channels (countries), you might want to view your live listing in every country you sell. To view your live listings, open the Product details page of the product. In the Listed channels and mappings widget, select a sales channel from the dropdown and click View on Leroy Merlin.

Note that on Leroy Merlin, the link always points to the French website, even if you select a different sales channel from the dropdown. This is a known limitation of this channel.

Can I map attributes on ChannelEngine and on the Mirakl platform?
No. Mapping attributes on the Mirakl marketplace platform interferes with ChannelEngine's content export. Therefore, it is recommended to categorize and map content only on ChannelEngine.

Why am I not receiving feedback on my content and/or offer exports?
Chances are that you are receiving the feedback. However, different types of error reports can take a couple of hours or several days to be generated:

• Offer feedback
  • Error reports are mostly generated automatically and are imported quickly.
• Content feedback
  • Transformation error report - this is automatically generated, and usually imported within a maximum of one day.
  • Conventional error report - this requires a manual review by the Mirakl-based marketplace, and not all do so. It can take several days for this report to be imported.

Note that the previous feedback report is not removed from ChannelEngine until both the latest transformation and the conventional reports have been fully processed by ChannelEngine. If there are no errors to report, no new reports are generated.
