[NEWS] Usuniemy endpointy dotyczące płatnego oznaczenia rabatu ilościowego na kilka sztuk tego samego przedmiotu / We will remove endpoints regarding paid quantity discount marking on several pieces of the same item

Od **12 lutego 2024** dodanie płatnego oznaczenia na liście ofert dla rabatu ilościowego nie będzie możliwe. Wymaga to również zmian w publicznym API.

**Co zmieniamy?**
1. Zasoby do płatnego oznaczania rabatu ilościowego oznaczyliśmy jako **deprecated**:

- [POST /sale/loyalty/promotion-campaigns](https://developer.allegro.pl/documentation/#operation/addPromotionToCampaignUsingPOST) - składanie wniosku o włączenie płatnego oznaczenia rabatu ilościowego na jednej ofercie,
- [GET /sale/loyalty/promotion-campaign-applications/{applicationId}](https://developer.allegro.pl/documentation/#operation/getPromotionCampaignApplicationUsingGET) - sprawdzanie statusu wniosku,
- [GET /sale/loyalty/promotion-campaigns](https://developer.allegro.pl/documentation/#operation/getPromotionCampaignsUsingGET) - pobieranie listy kampanii,
- [DELETE /sale/loyalty/promotion-campaign-applications/{applicationId}](https://developer.allegro.pl/documentation/#operation/deletePromotionCampaignApplicationUsingDELETE) - usunięcie wniosku,
- [DELETE /sale/loyalty/promotion-campaigns?promotion.id={promotionId}](https://developer.allegro.pl/documentation/#operation/deleteCampaignFromPromotionUsingDELETE) - usunięcie kampanii.

2. **12.02.2024** - **usuniemy** zasób, który umożliwia składanie wniosku o włączenie płatnego oznaczenia rabatu ilościowego - [POST /sale/loyalty/promotion-campaigns](https://developer.allegro.pl/documentation/#operation/addPromotionToCampaignUsingPOST).

3. **12.03.2024** - **usuniemy** pozostałe endpointy.

----

From **February 12, 2024**, it will not be possible to add paid marking to the offer list for quantity discount. This also requires changes to the public API.

**What are we changing?**
1. We have marked resources for paid quantity discount marking as **deprecated**:

- [DELETE /sale/loyalty/promotion-campaigns?promotion.id={promotionId}](https://developer.allegro.pl/documentation/#operation/deleteCampaignFromPromotionUsingDELETE) - delete a campaign.
2. **February 12, 2024** - **we will remove** the resource that allows you to apply for the inclusion of paid quantity discount marking - [POST /sale/loyalty/promotion-campaigns](https://developer.allegro.pl/documentation/#operation/addPromotionToCampaignUsingPOST).
