In the current e-commerce environment, expanding your reach across multiple marketplaces is no longer a choice—it’s a necessity. ChannelEngine offers a robust integration solution that seamlessly links your product catalogue to more than 950 international marketplaces, such as Amazon, Walmart, Zalando, CDON, Wayfair, and many others. It centralizes everything from listings and inventory to pricing and returns, making multichannel selling faster, smarter, and scalable.

However, effectively using ChannelEngine goes beyond the initial setup—it demands continuous refinement.

Here’s a breakdown of the essential tasks every ChannelEngine user needs to be proficient in.
How to Simplify Your Marketplace Operations using Channel Engine?

1. Product Categorization

Categorization ensures your products appear in the correct sections of each marketplace. ChannelEngine offers several methods:

Manual Matching: Match your internal categories to marketplace categories using keyword search or browsing tools.

1. Sign in to ChannelEngine and select your account. This will take you to your account’s main dashboard.
2. Navigate to the “Channel” section where you intend to manage product listings. This will direct you to the dashboard specific to the selected channel.
3. In the categorization section, you’ll first need to create groups of the similar products then need to complete any missing category assignments.
   Start by identifying the product type. Group the similar products under one product type.

To update a product’s category for each of the product type, open the “Browse” menu, search for the appropriate category, and select the relevant option by clicking “Select” and save the changes.

Other ways to categorize your products include:

AI Category Mapping:
Automatically suggests the most relevant categories based on product titles and descriptions.

Rules-Based Categorization:
Create if-then rules to split broad categories (e.g., “bags” into “shoulder bags” and “backpacks”).

Use filters to identify uncategorized products and apply rules accordingly.

2. Attribute Mapping and Error Resolution

Content Mapping:
Includes –

Mapping all required attributes like title, brand, color, and description.

Use fixed values, advanced rules, or replacement tags to customize content.

For optional attributes, match your attribute values to marketplace-approved values (e.g., color options).

Use auto-matching or manually select from dropdowns.

Error Resolution:

Errors can pop up for all sorts of reasons – missing data, mismatched formats, or marketplace-specific rules. Here’s how to tackle them:
Review Error Logs – Navigate to the Listed Products section to identify specific error messages.
“All updates and changes should be made in the Mappings section based on the type of errors.”

Common Fixes:

• Missing Attributes: Ensure all required fields (e.g., EAN, title, description) are mapped correctly.
• Invalid Values: Use predefined marketplace values or correct formatting (e.g., weight units, condition types).
• Offer Rejections: Check pricing rules, stock levels, and marketplace-specific restrictions.

Some common types of error examples:

1. Error 8541:

This issue arises when the product information we submit differs from the data already present in Amazon’s catalogue. The system flags an error indicating that the barcode being used is already associated with an existing ASIN. This typically occurs due to discrepancies in key identity attributes such as the brand name, manufacturer, item name, or part number.

How to Fix This Error

Step 1: Confirm if the ASIN listed in the error message matches your product.

1. Use the barcode to search in “Listed Products”
2. Check the ASIN on Amazon Seller/Vendor Central under “Add Products”
3. Verify that the ASIN linked to your barcode matches the ASIN in the error

“Note:  

Please verify the replacement terms suggested in the error to ensure they are accurate and appropriate.

Check the brand’s official website to confirm its relevance before updating the brand name.”

Step 2: To update the attribute, navigate to: Listed Products > View

Step 3: Copy the category assigned to the product in the mapping under channel.

Step 4: Navigate to Content Mappings and search for the category you copied.

Step 5: Look up the SKU and identify the attribute triggering the error (e.g., “manufacturer” or “brand”) using Ctrl + F.

Step 6: Update the value for the relevant attribute and click Save.

To modify product titles:
Go to Mappings > Content Mappings > All Products, search for the SKU, and paste the correct title into the “item_name” field. Click Save to apply changes.

2. Error 90244:
   This error occurs when the attribute ‘Unit Count Type’ has an unsupported value, such as ‘unit count’.
   Resolution:

Step 1: Navigate to Listed Products and click View on the affected SKU

Step 2: Go to Mappings > Content Mapping

Step 3: Choose the product category, then use the search bar to find the product using SKU

Step 4: Locate the “Unit Count” attribute, enter the correct value and unit, then click Save to apply the changes.

3. API Errors – 8560 / 13013:
   If a product remains unpublished and these are the only errors showing (with no additional issues), you may temporarily remove the product from the Product Selection list and re-add it after 24 hours.
4. Error 18448 – Missing Attribute:
   This indicates that a required attribute is not mapped. Add the missing value either through Content Mapping or Offer Mapping. If the attribute is not found in both, it needs to be defined before proceeding.
5. Errors 5461 / 100550 – Listing Approval Required:
   These errors suggest that listing approval is necessary. You can verify this in the Seller account by navigating to Manage Inventory > Suppressed Listings. The status will show as Approval Required.
6. Errors 100528 / 100527 – GPSR Compliance:
   These relate to General Product Safety Regulation (GPSR). Check if the relevant GPSR attributes are present in Content Mapping. If already filled, look for other potential errors and address them. Once resolved, the issue should clear automatically.
7. Errors 18027 / 100581 – Image-Related Issues:
   These errors are typically due to non-compliant images. Ensure the main image has a plain white background and does not include any watermark or text. If needed, edit the image to meet these standards and re-upload it manually via the Seller portal, especially if the product already exists in the catalog.

• Advanced Troubleshooting:
  • Use the Content Mappings tab to override or clear problematic values.
  • Wait 24 hours after making changes before re-listing affected SKUs.
  • Refer to marketplace-specific guides (e.g., Amazon, Bol, Walmart Etc.) for tailored solutions
