If your application is approved, you must sign a formal seller contract and complete the KYC (Know Your Customer) process. The contract is provided and explained in detail during a personal (digital) meeting with the GALERIA Marktplatz partner team.

Associated costs

Galeria does not charge an initial setup fee. However, approved sellers pay a monthly fee of EUR 30, and commission fees are reserved on sales. The exact commission fee percentage differs per product category.

Setup

On ChannelEngine

Connection

1. This channel is a Mirakl-based channel. Therefore, you connect to it with your Mirakl Connect SSO account. For more information on configuring Mirakl Connect SSO with ChannelEngine, check out the Mirakl-based channels: SSO authorization article.
2. If you would like to test the order flow with this plugin, contact the ChannelEngine Support team to configure the connection of your plugin to support testing. For more information on testing orders, check out the article ChannelEngine: how to create test orders.

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

The category tree is presented in German.

Mappings

While Galeria’s product attributes are presented in English, your input must be in German.

All products (required)

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.

• Article nr - the unique article number or internal product identifier (the seller's SKU) used to track and match the product across systems, feeds, and orders.

• Article title [de] - the product title in German (mandatory for the German market), which appears in search results, listings, and on the listing. Must be descriptive, SEO-friendly, and compliant with GALERIA's content guidelines (e.g.: max length, no promotional spam).

• Image 01 (main image) - the primary product image (first/main photo), which serves as the hero image on the product detail page. Must be high-resolution, white-background preferred, professionally shot, and show the product clearly from the front/best angle. Image guidelines:

  • The maximum file size is 10,240 KB, and the supported file formats are JPEG and PNG.

  • Please also refer to the Galeria Styleguide for Mirakl Partners.

• Product nr - the parent article number to identify product variants. All items that have the same Product nr. belong to the same family.

All products (optional)

• Article description [de] - the full product description in German, providing detailed features, benefits, materials, sizing, care instructions, etc.—must be informative, accurate, and adhere to GALERIA's quality/content guidelines (no misleading claims, proper formatting).

• Image 02-10 - additional product images (e.g.: variant, detail, lifestyle shot, or close-up). Enriches the listing, helps reduce returns by showing the product from multiple angles/materials/textures, and improves conversion rates (higher-quality, varied images are strongly encouraged).

• Tax classification article - (steuerklassifikationartikel) the product's tax classification or tax code for German/EU VAT purposes. Select Reduced (7%) for 7% VAT or Full (19%) for 19% VAT. If you do not set a value, Galeria will use Full (19%) as the default value. This value is then used in orders.

Offer

Required

• GTIN - the GTIN of the item.

• Price - the item’s base price/regular sales price. If a discount is created in the Pricing step, this price becomes the 'from' price. Enter a decimal value. Do not enter a currency. If pricing v2 is activated in your tenant, the Price attribute does not appear. Follow the steps in the section “Working with discounts”.

Optional

• Recommended retail price - the MRSP of the item.

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.

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.

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

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.

Additional information

Shipments

Tracking codes are required, but return tracking codes are not required. In addition to the list of carriers that Galeria maintains, you can ship with any unregistered carrier.

FAQs

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

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.
