Decathlon Marketplace Integration in M2E Cloud

This guide explains how to connect, configure, and manage the Decathlon marketplace in M2E Cloud.

It focuses on what you need to set up inside M2E Cloud and how Decathlon behaves as a Mirakl-based marketplace. This means Decathlon follows Mirakl standards for product data, offers, pricing, and order processing.

ℹ️ Many rules described here also apply to other Mirakl marketplaces supported by M2E Cloud.

What happens outside M2E Cloud #

Decathlon is a global sporting goods retailer that operates its own marketplace. It connects brands and merchants with customers looking for sports equipment, fitness gear, and outdoor products.

Decathlon operates across several countries, including Belgium, Czech Republic, France, Germany, Hong Kong, Hungary, Ireland, Italy, Luxembourg, Netherlands, Poland, Portugal, Romania, Spain, Switzerland, and United Kingdom. 

Each region may use a different currency (CHF, CZK, GBP, EUR, PLN, RON). If you sell in multiple currencies, you may need separate marketplace accounts and separate connections in M2E Cloud.

Who Decathlon is a good fit for #

Decathlon works best for merchants that sell branded sports and fitness products with clear product identifiers.

Good fit:

• Sports equipment sellers
• Fitness and wellness brands
• Cycling, running, and gym gear suppliers
• Outdoor and camping product sellers
• Urban mobility products (e-scooters, bikes, accessories)
• Brands with strong GTIN/EAN coverage

The marketplace favors structured product catalogs with reliable identifiers and consistent product data.

Requesting a Decathlon seller account #

Decathlon is a closed marketplace. To start selling, you must request access directly through Decathlon Seller Page.

During onboarding, Decathlon typically requests:

• A signed contract
• A completed onboarding questionnaire
• A list of brands you plan to sell
• Brand logos and product information
• Company and operational details

Decathlon reviews each application manually. Approval timelines vary by category and region.

Once approved, you will receive access to the Mirakl seller back end. This includes the API credentials required to connect Decathlon to M2E Cloud.

Keep in mind:

• Some categories require additional approval
• Brand authorization may be requested
• Selling permissions are defined by Decathlon

You can only proceed with the M2E Cloud connection after your Decathlon Mirakl account is active and fully approved.

Fees and payments #

Decathlon uses a predictable fee structure. Commission rates depend on the product category.

• Setup fee: none
• Monthly fee: EUR 40.00
• Commission: usually 10-18%, depending on category
• Payments: typically issued three times per month

What happens inside M2E Cloud #

Once Decathlon is connected, M2E Cloud becomes the control center for your marketplace operations.

You can manage product data, pricing, orders, and synchronization without working directly in the marketplace back-end for every change.

With the Decathlon Mirakl integration in M2E Cloud, you can:

• Connect your Decathlon seller account using API credentials
• Export products from your store to the marketplace
• Map categories, attributes, and offer data
• Apply pricing and currency rules
• Import and process orders
• Send shipment and tracking updates
• Monitor validation results and fix issues

The integration keeps your store and marketplace aligned. Product data, stock levels, and order updates can sync automatically once everything is configured.

This section covers the actions you perform in M2E Cloud to prepare your catalog and manage synchronization.

Requirements before you start #

Before connecting Decathlon to M2E Cloud, make sure the following requirements are met. Missing any of these may block exports or order processing.

ℹ️ Make sure your store runs on a supported platform such as Shopify, BigCommerce, PrestaShop, etc. All M2E apps are available in the official app listings. For example, a Shopify Hygi.de integration by M2E requires installing the Shopify app first.

Account and access

• Approved Decathlon seller account
• Active Mirakl seller access
• API key available from Mirakl

Product data

• Valid EAN/GTIN codes for all products
• Products assigned to supported categories
• Complete product content (titles, images, attributes)

Decathlon mainly operates in EUR, but some regions use other currencies. If you sell in multiple currencies, you may need separate marketplace accounts and separate connections in M2E Cloud for each currency region.

Decathlon is a MiMissing attributes or invalid identifiers cause most listing errors Connect Single Sign-On (SSO).

You need access to your Mirakl Seller Admin and a valid API key.

Connection steps

1. Log in to your Decathlon Mirakl Seller Admin.
2. Generate or copy your API key.
3. In M2E Cloud, open the Connect Mirakl Account.
4. Paste the API key.
5. Select Decathlon from the marketplace list.

✅ Find the step-by-step instructions in the M2E Cloud guide.

Common connection issues

If the connection fails, check the following:

• Incorrect marketplace URL
• Invalid or regenerated API key
• Account not fully approved yet
• Missing API permissions in Mirakl

ℹ️ If you regenerate your API key later, update it in M2E Cloud. Otherwise, synchronization will stop.

Once connected: What happens next? #

After the connection is established, configure how products and orders behave in M2E Cloud.

1. List new products on Decathlon #

You can choose store products and export them to Decathlon as new listings.

After export, these products appear on the marketplace and can be managed from M2E Cloud. Stock and price updates will sync based on your store data and policies.

2. Link existing marketplace listings with store products #

If products already exist on Decathlon and use the same SKU as your store items, M2E Cloud can automatically link them.

You can also link products manually using a CSV file. This is useful when SKUs differ or when you need to control which listings are synchronized.

Linking tells M2E Cloud which store product controls the quantity and price of each marketplace offer.

This step determines:

• which existing listings are managed by M2E Cloud
• which inventory values update on Decathlon
• which prices are synchronized

3. Map categories and required attributes #

Before exporting any product, you must map categories and attributes.

This includes:

• assigning each product to a Decathlon category
• mapping required attributes
• providing valid EAN/GTIN values
• filling language-specific content fields

Some categories require additional fields such as dimensions, composition, or usage details.

Decathlon supports product variations, but variation data must be structured correctly and include a parent identifier.

If required attributes are missing or invalid, the marketplace will reject the product.

For a deeper explanation of how product details move between your store and the marketplace, see the Synchronization Policy guide.

4. Configure pricing and currency rules #

Pricing behavior is controlled through selling policies in M2E Cloud.

At this stage, you define how prices and quantities are sent to Decathlon.

This includes:

• dase price source
• quantity rules
• currency conversion
• country-specific pricing
• discount configuration

M2E Multichannel Connect allows you to create multiple Selling Policies, so you can apply different pricing, quantity, and listing rules to each product group.

5. Configure order settings and status mapping #

Define how Decathlon orders are imported and processed.

This step controls:

• whether orders are imported
• how marketplace statuses map to store statuses
• shipment confirmation back to Decathlon
• tracking number synchronization

A correct order policy prevents status conflicts and keeps order data consistent across systems.

6. Set up shipping rules and delivery settings #

Shipping in M2E Cloud is managed through shipping policies, which control how orders are fulfilled and how shipment information reaches Decathlon.

Here, you define how products are delivered and how tracking data is synchronized with the marketplace.

Key configurations include:

• Selecting available shipping methods for Decathlon orders
• Automatically sending shipment confirmation and tracking information back to the marketplace

7. Monitor listings and resolve issues #

After setup, use M2E Cloud to keep an eye on your listings and ensure smooth operation.

The Listings page lets you:

• Track export results and validation feedback
• Spot errors in policies, attribute mapping, or pricing
• Correct issues directly without pausing or disconnecting the marketplace

This keeps your catalog accurate and up-to-date while minimizing disruptions.
