Linking offers to the Catalog
What rules apply to unlinking offers from products in the Allegro Product Catalog
In specific cases, we can unlink your offers from the product in the Catalog. Check what you can do then.
In the Allegro Product Catalog, we gather all products available on Allegro along with their edetails — such as parameters, images, or descriptions. This way, buyers can quickly find the product they ar searching for and easily compare all the offers with that product.
We regularly verify the links between offers and products to ensure their high quality. This allows us to provide buyers with clear and trustworthy information.
According to Appendix 10 to our Terms & Conditions — as the seller, you are fully responsible for correctly linking your offer to a product in the Allegro Product Catalog.
When we can unlink an offer from a product
We want buyers to be sure that your offer matches the exact product they are looking for. If your offers are incorrectly linked to a product from the Catalog, we can unlink them. We will then end your offer automatically. We will let you know about it by email.
We can unlink your offer from the Allegro Product Catalog if, among other things:
- the offer title indicates a different product than the one presented
- the basic parameters you provided in your offer differ from the product's details in the Catalog. You can check them in the Basic parameters section of the listing form.
- the photos of the goods in the offer differ from the photos of the product
- you provided a different number of units in the offer than in the product
- you offer the goods in a color version not included for that product.
We can also take into account:
- GTIN (EAN, ISBN, ISSN, or others) — a unique number that indicates the product itself and not its owner. This way, the same product can be linked to offers from different sellers.
- information on whether the product's and offer's categories are in a set of similar categories.
When we do not unlink offers from products
The products in the Catalog are available to all sellers on Allegro. If your believe your offer is linked to the wrong product, you can report it to us. See the relevant provision in our Terms & Conditions:
According to Appendix 10 of the Allegro Terms & Conditions (Section 1.8): "Upon entering the data and content in relation to the Product proposal, the User creating the proposed and target Product shall give the Company the rights and consents specified in paragraphs 5.1 and 5.5 of the Allegro Terms & Conditions (which shall apply accordingly) in regard to all the content and elements. Upon entering the Product proposal, the User shall lose the ability to edit the data and content added to the Product specifications card. The User may, however, report to the Company any errors and mistakes that took place while entering the Product proposal, using the relevant functionalities on Allegro."
In some cases, despite receiving a report, we have no reason to unlink the offer from the product.
This applies to situations where, among others:
- there are no differences between the goods in the offer and the product
- the only difference is the GTIN (EAN, ISBN, ISSN, or others) — a unique number that indicates the product itself and not its owner. This way, the same product can be linked to offers from different sellers.
- the report concerns, for example, lower product quality — we are unable to verify this if there are no differences between the goods in the offer and the product
- the report concerns a different violation in the offer — report such cases through the form, selecting the appropriate reason. Remember to add a justification — it may help us review your report more quickly.
- you believe someone has violated your intellectual property rights and you have documents that confirm your ownership of those rights. In that case, contact us. Learn more.
Note: We can review your report only if you provide us with the necessary documents.
What will happen when we unlink your offer from the product
If we unlink your offer from the product, we will terminate it automatically and let you know about it in an email.
See an example of such a notification:
In the email, you will find a link to the My Assortment tab. Click it and check the list of offers we unlinked from the product.
How to list an offer in a different category than the one assigned to the product from the Catalog
Find out what collections of similar categories are and how they work
When you list an offer linked to a product from our Catalog, it appears in the category we have selected. If you want to change it, you can select another one from a set of similar categories.
What a set of similar categories is
We have combined similar categories into sets. Within such a set, you can list offers linked to the same product in different categories.
Example
You list reflective bands in your offer. When you select a product from our Catalog, your offer will be automatically assigned to the Kids — Mother and Baby Accessories — Safety — Reflectors category. You can change it, for example, to Sports and Travel — Running — Hi-Vis Accessories or Sports and Travel — Bicycles and Accessories — Accessories — Hi-Vis Reflectors, as both of these are included in the set of similar categories.
What categories are included in the sets
Currently, there are several thousand categories in sets. Download the list. .
How to list an offer in category from a set
When you list your offer and select a product from the Catalog , you will see the default category assigned to this product in the Catalog. To change the category of your offer, click [edit] and select one of the categories from the set.
When you do this:
- we will not remove the previous link to the product
- we will complete the GTIN (EAN code) in accordance with the product information in the Catalog
- we will complete the selected parameters with product details
- you will complete the remaining obligatory parameters yourself.
How to add new categories to the sets
If the category in which you want to list an item linked to a product is not on the list, contact us. Our experts will check whether we can add your suggestion.
What if we reject your suggestion
If it turns out that we cannot create a set based on your suggestion, you can only link your offer to the selected product in the Catalog if:
- you change the category of your offer to from the same set as a given product or
- we change the category of that product.
Product search engine — what it is and how it works
You can use the product search engine in the listing form. Thanks to the search engine, you can find a specific product in the Catalog and use it as a base for your new offer on the platform. You can also learn more about the assortment on Allegro.
How to use the product search engine
- Go to the listing form. Enter the GTIN (EAN) in the search bar, and click [search]. Based on that, we will scan the Allegro Product Catalog to find matching products.
Check whether the product you want to sell is on the list. If not ― you can click [continue without selecting a product]. We will try to create a new product based on the information you provide in the listing form. Learn more.
Once you select the product, click it. We will display the details — a set of parameters like, for example, color — that describe the selected product. The parameters will help you decide whether you have found the right product.
We want the products available in the Catalog to be top quality. If you spot an error in the product details ― report it instead of correcting it only in the listing form. Click [report incorrect product information] on the product card.
- If the product parameters are correct and you want to list an offer based on them, click [select].
What if you only want to use the search engine without listing any offers? In that case, click this link.
If you use the Allegro API
To find a product in the Allegro Product Catalog, use the GET/sale/products resource. Learn more.
If you know the GTIN (EAN) or the product ID, provide it in the product.id field, in the POST/sale/product-offers request structure. In that case, you will only use the product from our Catalog. We will not create a new product, even if you provide all the necessary details.
Do not complete the product.id field if you want to add a new product to the Catalog. Provide the GTIN (EAN) and other details in the product.parameters field.
Frequently asked questions
I cannot find a specific product even though I can see offers on Allegro that are linked to it.
The product in that offer may be incomplete — it may not contain all the details required for that type of assortment. In that case, contact us using the form.
I think that the product parameters are incorrect and I want to change them.
First, check if you have searched for the correct product variant. For example, if you are searching for iPhone 11, there are already several model versions. In that case, select the proper variant first.
If you are sure that the parameters are incorrect, click [report incorrect product information]. Learn more.
I have found the right product, but I cannot list the offer in the category that suits it best.
Remember that the category in which you want to list your cataloged offer and the product category have to match. If you want to change that category, you can select another one — from the set of similar categories. Check how it works.
If you think that the product category is incorrect, you can suggest its change.
Temporary products — what they are and how they work
Do you want to catalog your offers, but cannot complete some of the obligatory parameters, or your product is unique? In such situations, we can create temporary products. This way, you will be able to list an offer and link it to the Allegro Product Catalog.
We know that for some categories, it may be difficult to provide all the identifying parameters — for example, in the case of used products. Apart from that, some products are unique and it is not possible to create one set of parameters suitable for all products in a given category. For example, in the Figurines and Sculptures category, you can sell both garden decorations and ethnic handicrafts.
What temporary products are
- We can create temporary products for items that are unique and difficult to replicate and catalog — such as antiques, art, collectibles, or digital services. We can also create them for charity offers
Example
We create such temporary products in subcategories within the Collections and Art category, for which we require the EAN (GTIN) parameter.
- We do not link your temporary products to other offers. One temporary product is only linked to one offer.
- We will not show temporary products in the product search engine. This means other sellers will not link their offers to your temporary products.
How we create temporary products
We will create a temporary product when you list or edit an offer via the listing form, the API, or the List from file tab. We will use:
- the title
- the images in the gallery
- the category
- the parameters.
