Marketplace-specific requirements and exceptions

Setup

On ChannelEngine

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

Invoice uploads

To configure your invoice settings, click Advanced settings. You can then click the dropdown menu Enable invoice uploading, which contains the following options:

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

Mappings

Content

All products (required)

• Image principale - the product's main image. This is the first image shown on Auchan. The requirements are:
  • Background - white background
  • Resolution - 1200x1200 px, 72 dpi minimum
  • Format - GIF, JPEG, PNG, WEBP
  • No logo or text information
• Libellé du produit - the product's title, in French. The maximum number of characters is 100. 
• Long description - the product's long description of up to three paragraphs, in French. There is no limit to the number of characters. HTML formatting is supported. 
• Marque - the product's brand selected from the list of values.
• Poids - the product's weight, in kg.
• Produit décliné (Declined product)- indicates whether this is a parent product with variations, such as different sizes or colors, or a child product. Enter a value of '1' if the product has variations. If the product is a child or a standalone product, map this attribute to '0'. 

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

• Export strategy - choose a strategy for exporting the product data. You can select from the following export strategies:
  • Yes - export all of the product content to the marketplace, including its 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)

• Article parent - the parent product's SKU that is common to all variations of a product. This attribute is mandatory if the product has variations, i.e.: if the Produit décliné attribute is mapped to '1'. 
• Couleur liste [variant attribute] - used to create product variations, the product's color selected from the list of values.
• EAN [FR] - the product's 13-digit EAN. Although it is marked as optional, this attribute is required for all products, except for parent products with variations. 
• Image 2-6 - the product's additional images. It is recommended to provide as many images as possible. For image requirements, check Image 1.
• Mots clés - the product's keywords that specify important product features.
• Redevance TV - Auchan does not use this attribute for TV products, therefore you can ignore it. 
• Short description - the product's short description. The maximum number of characters is 200. HTML formatting is supported.
• Taille [variant attribute] - used to create variations of the product, the product's size selected from a list of values.
• Taxe alcool - products with alcohol are not allowed to be listed on Auchan, therefore you can ignore this attribute as it is not in use. 

Offer

Required

• Price - the product's regular selling price, excluding the VAT. If you use pricing v2, this attribute is not mapped under Offer mappings. Instead, it is configured under Pricing, Price rules.
• TVA - the VAT rate that applies to the product.

Optional

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. For a list of category codes, check out the article Providing data to comply with circular economy regulations in Mirakl's help center (note that you need to be logged in to Mirakl to access this page). 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.

The following offer attributes are common to all Mirakl-based marketplaces, if you use pricing v2:

• 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.
• Fee groups - the ID of the fee group you want to assign to this product. To learn more, check out the article ChannelEngine: marketplace fees.
• 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. 

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

• Discount end date - the date until when the product's sale price is valid, if applicable. The date format is YYYY-MM-DD HH:MM:SS ZZ. E.g.: 2022-12-31 23:59:59 +00.
• 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.
• Discount start date - the date from when the product's sale price is valid, if applicable. The date format is YYYY-MM-DD HH:MM:SS ZZ. E.g.: 2022-12-31 23:59:59 +00.
• 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 it using the marketplace’s codes, not the labels visible in the front-end. These codes vary per marketplace. If this marketplace makes use of logistic class codes, they can be found below.

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 – otherwise, the export is broken.
• To set a bulk discount, the Discount quantity threshold must be set to a value higher than 1. E.g.: a value of 2 indicates that two or more of the product must be purchased at the same time for the buyer to benefit from the discount.

Pricing v2

• To set up a discount, map the Strike price attribute to your regular price. Also, map the Discount start date and Discount end date attributes to indicate the start and end date of your discount.
• Under Pricing, 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 the ChannelEngine: price rules v2 article.
• 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.
• Same as in pricing v1, 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. E.g.: a value of 2 indicates that two or more of the product must be purchased at the same time for the buyer to benefit from the discount.

Carrier

Carrier mapping is not required on Auchan. However, you can map your carrier to a specific list of carriers maintained by Auchan. This allows for working tracking codes in the back-end, as well as for the buyer. If your default carrier is missing, please contact Auchan.

Pricing

Auchan requires the prices to be submitted in EUR. If you do not have pricing attributes in EUR, you need to set a currency conversion.

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.

You can either use the Channel status filter (e.g.: products that ChannelEngine has failed to export, such as those with an empty GTIN or that do not exist on the marketplace yet, are shown as Invalid) or the Validation and feedback tab to see all known errors for specific products.

Alternatively, you can access the marketplace's back-end and download the error report generated by Mirakl. To do so:

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

Additional information

Order extra data items

When an order is imported to ChannelEngine, ChannelEngine also fetches extra data items related to the order itself – or to order lines. This extra data is specific to this marketplace. An explanation of each can be found below: 

Order extra data

Keys	Conditional*	Description
consent-contact	Yes	L'accord du client sur la visibilité de ses messages auprès de l'opérateur (Customer agreement on the visibility of messages to the operator)

* Conditional fields are only displayed if the marketplace provides a value.

FAQs

How often does each task run on Mirakl-based marketplaces?

By default, Mirakl-based marketplaces follow the schedule below:

Task	Frequency
Export product data to marketplace	every 60 minutes
Export product offers to marketplace	every 15 minutes
Import product offers from marketplace	every 15 minutes
Import orders from marketplace	every 15 minutes
Export order shipments to marketplace	every 15 minutes
Export returns to marketplace	every 30 minutes

Can I map attributes on ChannelEngine and in the Mirakl back-end?

No. Mapping attributes in the Mirakl marketplace back-end interferes with ChannelEngine's content export. Therefore, it is recommended to stick to categorizing and mapping content only on ChannelEngine.

Why am I not receiving feedback on my content and/or offer exports?

Chances are you are receiving the feedback. However, different types of error report 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 conventional reports have been fully processed by ChannelEngine – or no new reports have been generated because there are no errors to report.
