Product feed

Firstly, you must have the Product Feed set. It contains all product essentials, such as product brand, product description, price, special price or labels on products displayed online. This feed is used to create and edit products.

IMPORTANT: The structure and logic of this feed is unchangeable, please follow the steps below carefully.

Here you can download sample product feeds in .xml format.

A link to your product feed must be inserted in the Product feed box in the portal MALL Partner. After checking the box below it, the feed can be secured using the http Basic authentication, details can be found here. You will also find a diagram in XSD format here, suitable for validating the feed structure, which is described below.

After inserting a link to your product feed, it must be saved. Afterwards you can choose to either process it manually or an automatic synchronization after 6/12 or 24 hours can be set. Note that if automatic synchronization is set, you cannot process the feed manually. If you want to process the feed manually, you must primarily turn off the timer, by setting DISABLED, and then save.

IMPORTANT: All products, even if they are not in stock, must still be kept in the Product Feed. Their availability is controlled using the Availability feed.

Sorting parameters and categorization

In order for the products to be displayed correctly on the page, it is necessary to provide two basic data, namely the category code and sorting parameters. You can find both necessary data from the category tree for the given country, which is sent to you by our sales representative, or you can find the necessary data in the MALL Partner portal in the section Category.
A more detailed description of categories, sorting parameters and their values can be found in the article here.

IMPORTANT: Sorting parameters with a value assigned to them are mandatory. Without specifying these parameters, the product will not be displayed on our website.


For the correct display of your products online, it is necessary to pay attention to the possibility of creating groups of variant products, e.g. a T-shirt in 10 colour variants and 5 sizes is required as one product group/variant product. For the creation of product variations, you will find below the specific elements that must be used. For creating variants these three basic data are important:

  1. Identifier of a group of variant products
  2. Identifier of MAXIMUM 2 PARAMETERS based on which this group differs (typically color, size, material)
  3. Indicating parameter value based on which the product group differs

Error log

To check the processing result of your Product Feed, use the log button, under which you will find the results of all processing. If an error occurs, it is listed in the list of errors, which you can access by clicking on the icon at the end of given line. Here you will find a list of all errors that our database found. If any record is not understandable, please contact the responsible person or ask your IT specialist for advice. At the same time, please note that the error log only records errors that our databases can detect. Errors caused by wrongly set values for listing in categories cannot be detected in this way.

IMPORTANT: The database always checks each of your products until it finds an error in the data. If this happens, the product will call up an entry in the error log and the database will read other products in your feed. Therefore, if you have more than 1 bug in a given product, this cannot be detected the first time it is played.

XML feed structure

IMPORTANT: All elements are mandatory, except for the fields marked as optional. The same applies for their order.

Product display

After uploading your products from the product feed successfully, it is necessary to complete the controlling of all requirements necessary for products listing to the desired category. Please do this check after the successful synchronization of the product feed and uploading products is complete.

To check the products, first go to the "Partner" section, the "Sandbox accounts" tab and you will find the generated login details, under which you log in to our website in the country in which you want to list your products.
Then, in the list of products, just click on the square icon at the end of the line next to the product. If the product is displayed, you have data in the feed corresponding to our database. You will find more detailed instructions here.

If you get a notification stating that the product failed to display, the sorting parameters may be entered incorrectly. Please first check with the category tree whether you have correctly entered sorting parameters with correct values to the feed. Next check whether you are logged in via the account you created in the Accounts tab. If none of the options work, get in touch with MALL contact person responsible for your technical input.
