Expanding to a new marketplace is an exciting opportunity, but incorrect setup can lead to listing errors, lost sales, and compliance issues. Configuring a marketplace channel on Lengow is a crucial step to ensure seamless integration between your product catalogue and your chosen marketplaces. Proper configuration helps improve overall marketplace performance.
This article highlights the most important points to check when configuring your marketplace channel in Lengow. Depending on the specific marketplace, you will find detailed and accurate information in the dedicated channel guide in the Help Center.
E-commerce Plugin Version
Lengow is compatible with most popular e-commerce platforms. Before importing your catalogue, review the plugin version, its compatibility & pre-requisites. Some features, mandatory for certain marketplaces, are only available in the latest e-commerce platform versions.
💡 Recommendation: Check the Help Center for up-to-date compatibility details.
Channel registration steps
Each marketplace has specific registration requirements. Missing a step can delay your integration and impact sales opportunities.
💡 Recommendations:
🔹Ensure your seller account is approved and active.
🔹Follow marketplace-specific onboarding steps.
🔹Consult your channel account manager for additional requirements.
🔹If you are a brand and wish to regain control over your product content, you can request the channel to recognize you as the official brand owner.
Switching from a previous integrator or manual setup
Migrating from another integrator or manual uploads requires careful planning to prevent conflicts, duplicate listings, data mismatches and order synchronization failures.
Key considerations during feed migration:
🔹Keep the same product identifiers (SKU, EAN) to ensure listing continuity.
🔹If possible, launch your channel in Lengow before deactivating your previous integrator.
Using "stock = 0 " on the previous integrator is usually applicable in this case.
🔹Start with a sample of products to verify accuracy before full migration.
🔹Schedule the switch at a time of lower business activity.
🔹Check directly with the marketplace for the best way to deactivate the old integration before enabling Lengow to avoid duplicate listings.
EAN matching
To save time and speed up your product listing, take advantage of EAN matching when available. By matching your offer to an existing product via its EAN code, you can skip the product creation step and directly send your price and stock information. This method is ideal for standard products already sold by other merchants.
💡 Recommendation: Check whether the marketplace allows/requires EAN-based product matching or if a complete product sheet is required.
Product Variations
Most marketplaces allow sellers to list variation products as independent items. However, using parent-child relationships to group these variations is highly recommended. It helps shoppers easily find all options in one place and makes managing your products simpler and more efficient.
Key Considerations:
🔹Some marketplaces require both parent and child products.
🔹Others only require child products, grouped by a common parent ID.
💡 Recommendation: Whenever possible, include parent products in Lengow so your catalogue is prepared for both cases. Check the Help Center for marketplace-specific rules.
Multi-country configuration
Selling in multiple countries requires proper configuration to comply with local regulations and pricing strategies.
💡 Recommendations:
🔹Use Multi-Country attributes for accurate publication.
Check the dedicated multi country section of the marketplace guide.
🔹Ensure currency, VAT, and pricing rules align with each country’s requirements.
🔹Adapt logistics information (shipping methods, delivery times, return policies).
🔹Translate product descriptions when required.
A one-size-fits-all approach can lead to compliance issues and pricing misalignment.
Other specific settings (e.g. images, category mapping, logistics info)
Each marketplace has unique requirements regarding product images, category mapping, and logistics details. Proper configuration improves product visibility, customer experience and sales.
Key Considerations:
🔹Images: Follow marketplace-specific size, format, and background rules.
🔹Category mapping: Assign products to the most relevant marketplace category.
🔹Logistics info: Configure shipping, handling times, and carrier mapping correctly.
💡 Recommendation: For specific marketplace requirements, refer to the each marketplace guide in the Help Center.
Test Orders
Before launching your products, testing the order process is essential to ensure that everything works correctly. Here are three ways to test:
1. Test orders in the sandbox environment
The Lengow Sandbox allows you to generate fictitious orders for testing order retrieval on your e-commerce platform or via API. However, these are not real interactions with a marketplace.
💡 Recommendation: While useful for connection tests, Sandbox orders do not replace live tests.
Validate with real orders as much as possible.
2. Doing a live test order yourself
Before going live, create a test order to detect pricing, shipping, return, or stock update issues.
💡 Recommendations:
🔹Test multiple scenarios: single product orders, multiple products, partial returns, international orders.
🔹Verify that product data (price, stock, shipping, taxes) transfers correctly.
🔹Ensure orders appear correctly in the Lengow dashboard and in your e-commerce platform.
3. Test orders required by marketplaces
Some marketplaces require a mandatory test order before approving the "Go Live".
💡 Recommendation: Check the order section of the marketplace guide in the Help Center for specific test order requirements.
