* A marketplace that supports sales channels allows merchants to list and sell products across multiple markets (e.g.: countries, regions, and states), all from the same connection. Merchants can sell across the above countries under the same contract and seller account by selecting the applicable sales channel. Tradeinn is available in many European countries, however, they are divided into the following sales channels:

• Spain (ES)
• France (FR)
• Germany (DE)
• Italy (IT)
• Rest of Europe (ROE) - Andorra, Austria, Belgium, Cyprus, Estonia, Finland, Greece, Ireland, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Portugal, Slovakia, and Slovenia. To opt out from selling to a specific country included in the ROE sales channel, disable it in the additional Excluded countries offer mapping.

Marketplace-specific requirements and exceptions

Setup

On ChannelEngine

Tradeinn 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 enable the invoice upload to ChannelEngine via the Merchant API. For that, call the POST /v2/orders/{merchantOrderNo}/invoice endpoint. Note that only invoices in PDF are supported.

Invalid XML characters

To remove invalid XML characters from your product data, click Advanced settings and enable the Check and filter invalid XML characters setting. ChannelEngine checks product data submitted in the XML format for invalid characters (e.g.: Ã, ¢, â, etc.). Once identified, invalid characters are removed or converted to a valid equivalent.

Categorization

Categorization on Tradeinn is straightforward, and all categories are provided in English. 

Mappings

Tradeinn is available in more than 20 European countries, but all attributes are labeled in English. To support Tradeinn's multi-lingual presence, all product content must be provided in English. There are various optional attributes available to allow you to provide localized content where needed. E.g.: the product title and product description. 

Content

All products (required)

• Brand name - the product's brand, selected from a range of fixed values. If your product's brand is missing, contact Tradeinn to have it added to the list. 
• Color - the product's primary color, which can be one of the predefined values. E.g.: red, brown, yellow, green, transparent, etc. 
• Color name - the product's color as defined by the manufacturer. E.g.: ebony/black.

This identifier is always composed of the root, color code, and size – all separated by hyphens. E.g.: for the MPN IB25471-234-M, IB25471 is the root, 234 is the color code, and M is the size.

• Size - the size of the product, using European sizes. E.g.: 41, 39 1/2, etc. Non-EU sizes should be indicated using letters, such as 2XS, XXL, 2XL, etc. For products that do not have a clothing size, such as electronics, use the value 'One size'.

E.g.: machine wash, fabric: 100% organic cotton. There are no character restrictions. The only accepted HTML tag for formatting is br.

Offer

All products

The only mandatory offer mapping is Price, which is your desired sale price in EUR.

The following offer attributes are common to some Mirakl-based marketplaces, particularly in France and Germany:

• 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 Mirakl-based marketplaces:

• 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.
• Minimum quantity alert - map this attribute to receive a notification from ChannelEngine 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. Below you can find the codes used by this marketplace:

Code	Label	Description
s	Small	Small items, less than 3 kg
m	Medium	Medium items. between 3 kg to 10 kg
l	Large	Large items, between 10 and 30 kg
heavy_prod	Heavy products	Heavy products, between 30 and 60 kg
freeshipping	Free shipping	Free shipping

Working with discounts

• To set up a discount, you must 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.
• If your discounted price is not lower than the base price, it is not exported.
• If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped – otherwise the export is broken.
• If you do want 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 mandatory on Tradeinn. You should map your carrier to a specific list of carriers maintained by Tradeinn. This allows for working tracking links in the back-end, as well as for the buyer. If your default carrier is missing, contact Tradeinn to have it added to the list.

Pricing

All pricing must be in EUR, even for the ROE sales channel. You can offer different prices per the following sales channels: France, Germany, Italy, and Spain. The sales channel ROE only allows one price to be applied per product for all the countries included in this category. E.g.: Austria, Belgium, Netherlands, Portugal, etc. 

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 filter on Channel status (select Invalid to show all products that ChannelEngine has not exported, such as products with an empty GTIN or that currently do not exist on the marketplace) or use the Validation and feedback tab to see all known errors for specific products.

For detailed status reports, go to the Mirakl back-end. Their reports contain specific errors if a product or product offer cannot be created. To find them, go to My inventory, Import from file, Track offer imports/Track product imports. By hovering over the 'i' under the Status section, you can see how many products in the file were processed correctly and how many had errors, etc.

If there are errors, the last column shows a downloadable file in which they are listed. The same goes for the product file import, but this can contain multiple files because processing goes through several systems. There is also a manual check of your submitted content, which, once approved, goes to staging as well. Note that you need to map as much as possible to prevent products from not being created.
