Remove/Undo promotion

[Former Member]

Hi Folks,

I am working on the custom promotion and i have a requirement to remove/undo the promotion applied from a cart entry when the user requested.

I found we can undo the promotions using cleanupCart method in promotionmanager and in inside cleanupCart method it is calling deleteStoredPromotionResultsmethod.

Can anyone share your suggestions how to proceed?

Thanks Aruna

I guess I'm late to the party but assuming you were talking about the legacy promotion engine, you could do something like this:

 boolean requiresRecalculate = false;
 Set<PromotionResultModel> promotionResultModels = cartModel.getAllPromotionResults();
 
 for(PromotionResultModel promotionResultModel : promotionResultModels) {
   PromotionResult promotionResult = modelService.toPersistenceLayer(promotionResultModel);
   requiresRecalculate |= promotionResult.undo();
 }

 customCartService.recalculateCart();
