[NEWS] Ustawiamy trwale wartość null w polu “ean” i obiekcie “eans” / We permanently set the null value in the "ean" field and the "eans" object

Zgodnie z [wcześniejszą zapowiedzią](https://developer.allegro.pl/news/#ean-eans-remove), od dzisiaj trwale ustawiamy wartość **null** w:

- polu “ean” w [POST /sale/offers](https://developer.allegro.pl/documentation/#operation/createOfferUsingPOST) i [PUT /sale/offers/{offerId}](https://developer.allegro.pl/documentation/#operation/updateOfferUsingPUT),
- obiekcie “eans” w [POST /sale/product-proposals](https://developer.allegro.pl/documentation/#operation/proposeSaleProduct),

i nie możesz jej już zmienić.

Od 29 marca 2021 całkowicie usuniemy pole “ean” z modelu oferty oraz obiekt “eans” z modelu produktu.

Skorzystaj z [**parametru globalny numer jednostki handlowej tzw. GTIN**](https://developer.allegro.pl/news/#gtin), aby uzupełnić EAN, ISBN i ISSN.

-------

According to [our previous announcement](https://developer.allegro.pl/en/news/#ean-eans-remove), from today we permanently set the **null** value in:

- “ean” field on [POST /sale/offers](https://developer.allegro.pl/en/documentation/#operation/createOfferUsingPOST) and [PUT /sale/offers/{offerId}](https://developer.allegro.pl/en/documentation/#operation/updateOfferUsingPUT),
- “eans” object on POST /sale/product-proposals,

and you cannot change it.

On March 29th, 2021 we will completely remove the "ean" field from the offer model and the "eans" object from the product model.

Use the [**Global Trade Item Number (GTIN)**](https://developer.allegro.pl/en/news/#gtin) parameter to add or change EAN, ISBN and ISSN.
