Best practices for Mirakl marketplaces

• In the Build step, some attributes may be mandatory even if they don't seem relevant for your specific situation (e.g. an attribute for adding a Spanish title when you’re only selling in Germany). You can leave these attributes unmapped.
• Adding multiple attribute values: Separate multiple values in an attribute with a pipe symbol "|" for proper detection and processing.
• Seller's Product ID for single/simple products: There are two attributes called SellerArticleId and SellerProductId. SellerProductId is the Parent ID, while SellerArticleId refers to variant items.

  • For single products, both SellerArticleId and SellerProductId must be filled with the same value.

Resolving common FNAC/Darty errors

How to fix ‘Cannot create offer’ FNAC/Darty errors

Example errors: ERR_206

FNAC Darty Offers channels in Channable can only send offer data (e.g. price, stock) to EANs that already exist in the Fnac Darty catalog. If you attempt to send an offer for an unrecognized EAN, Channable will not be able to create the offer.

To resolve this, you need to first create the item in your Fnac Darty seller account to attach offer information.

More of a visual learner? Follow Fnac’s step-by-step guides. In your FNAC seller account, go to Aide > Documentation > GESTION DES IMPORTS.

Step 1: Download excel template

1. Log in to your Catalog marketplaces Fnac Darty seller portal.
2. Go to Imports > File template.
3. For Distribution channel, select France or Belgium (based on your use case).
4. For the target market language(s), select the market you’re targeting (e.g. French in France = fr_FR).
5. Review the category tree and select the categories in your item catalog.
6. Scroll up and click Generate a product catalog import file. An excel file will automatically begin downloading.

Step 2: Fill in template

1. Open the downloaded Excel file in your spreadsheet software.
2. Review and fill in the sheet:

   1. For each item line, select the category/type from the drop-down menu.
   2. Enter the SKU, EAN, Manufacturer/seller, Label, Additional description and Main image per item.
   3. Provide data for any remaining mandatory attributes for your items, represented as columns in your sheet. (Key: red = mandatory, yellow = recommended, white = optional, grey = not applicable for this category).

If the SKU, EAN, wording and typology are missing, your file will not be imported at all. These mandatory fields can be modified but it is not possible to remove them or leave them empty.

Use the the Criteria tab of your sheet to see what type of data is expected in each column.

1. Save your completed Excel file.

Step 3: Upload your excel file

1. In your Catalog marketplaces Fnac Darty seller portal, go to Imports > Catalog import.
2. Drag the excel file into the ‘Drop and drop files here’ section to upload your completed sheet.
3. Confirm that the 4 mandatory fields (EAN, SKU, Category = Typology and wording) have been completed in the file you selected.

Step 4: Check the import files status’ history

1. On the Catalog import page, click History.
2. Check the Status column to check your import status:

   • Import in progress: Your uploaded file is being processed.
   • Invalid format: Your uploaded file format is incorrect. Download the error report to find out what caused this, fix it and import the file again.
   • Import completed: Your uploaded file has been successfully imported.
   • Import failed: Your uploaded file contains at least one error. Refer to your error report for advice on how to fix it.

Just like manual creation, successfully imported products will sit in a pending state until Fnac Darty validates them.

Step 5: Activate and run your FNAC Darty offers channel in Channable

Once your products are approved and live in the Fnac Darty catalog, your channel can attach offer information.

1. In [your FNAC Darty offers channel] in Channable, go to Settings.
2. Activate your channel if you haven’t already done so.
3. Click Run now.

Channable will match your EANs to the newly created catalog items and attach your specific price, stock, and shipping data to them.

How to fix ‘Product requires update’ FNAC/Darty errors

Example errors: ERR_111 , ERR_155

If your offer creation fails because a product is marked as unsellable, you must manually update the product data sheet in your FNAC Darty seller portal. Once the marketplace approves the updated data, Channable can resume managing the offer.

More of a visual learner? Follow FNAC’s step-by-step guide. In your FNAC Darty seller account, go to Aide > Documentation > FICHE PRODUIT to view their walkthroughs.

Step 1: Find the product in your Fnac Darty portal

1. Log in to your Catalog marketplaces Fnac Darty seller portal.
2. Go to Catalog > Product catalog.
3. Click on the product you want to update to open the product sheet.
4. Scroll down to the product attributes under Specification. You should see four attribute groups:

   • Mandatory attributes
   • Media attributes
   • Recommended attributes
   • Secondary attributes
5. Check the status of each attribute group:

   • Valid: all attributes in this group are correct
   • Invalid: at least one attribute is incorrect

Step 2: Update and resubmit the product data

1. Click Edit next to the attribute you want to update.
2. Update the attribute directly in the field.

   • To update media attributes, upload a new visual. Once the new visual is sent, delete the previous one.
   • If you change a category attribute, check all other attributes afterward, as required attributes vary by category.

     • If the attributes originally filled in the product sheet also exist in the new category, they are retained.
     • Any attributes that do not exist in the new category are lost. The new category attributes will appear empty and must be completed.

Make sure all mandatory attributes are completed accurately to prevent errors.

This modification usually takes the longest to process.

1. Click Validate to submit your corrections.

Step 3: Resume offer management in Channable

Once your products are approved and live in the Fnac Darty catalog, your channel can attach offer information.

1. In [your FNAC Darty offers channel] in Channable, go to Settings.
2. Activate your channel, if you haven’t already done so.
3. Click Run now.
