  2. Verifying EANs in the AlzaTrade portal
  3. Generating listing tables
  4. Uploading and reviewing listing tables

Selecting new products by EAN

Processing the product feed for listing consists of two parts:

  • Identifying products that Alza doesn't yet have in its system.
  • Generating listing tables with new products.

First, you'll need to compile a list of EAN codes for all products you want to list. Upload your product feed (for listing products) here as either a link or a file: https://listing.obsahovka.eu/cs/product_listing/xml_feed_listing/

Then select the Get EAN list option. This will generate a table containing all EAN codes from your feed. However, for the next steps, you only need the EANs of new products that aren't yet in Alza's system.

If the feed contains errors, the downloaded file will display an error report. Correct these errors and download the EANs again to avoid delays in the process.

Verifying EANs in the AlzaTrade portal

Verify the obtained EANs in the AlzaTrade portal under the Listing and Product Editing section.

  • If Alza doesn't recognise the EAN, proceed to generate the table.

  • If Alza already recognises some products, follow these steps:

Remove the EANs of products we already have from your table, keeping only those unknown to Alza.

Generating listing tables

Before generating listing tables, upload both the product feed (containing all product data) and the table with only new EANs (products not yet listed) to the portal. This ensures the system correctly identifies which products to use for creating the listing tables. Alternatively, you can enter a list of SKUs (supplier codes) instead of EANs.

Next, proceed to generate the table. The downloaded ZIP file will contain listing tables for each product category.

Uploading and reviewing listing tables

Before uploading, carefully review the tables. Ensure they contain all required listing information. If complete, you can upload the tables sequentially in the AlzaTrade portal under Listing and Product Editing – Upload .XLS Template.

The system automatically checks the table's data completeness and only allows uploads when everything is correctly filled. After clicking "Upload", the template is saved in the portal and added to the listing queue. You'll be notified once listing is complete—the process currently takes days to weeks, depending on data volume and accuracy.

Successful uploads will appear in the list of uploaded files.

If the table contains errors, an error report will appear (downloadable as a file) with the problematic cell clearly marked. If you need help resolving errors, contact support and attach both the upload table and error report.
