Hello everyone,

I have a subscriber for the&nbsp;_Shopware\_Modules\_Basket\_UpdateArticle\_Start_&nbsp;event&nbsp;_._

Background: I would like to check the graduated prices every time the shopping cart is updated - these come from an external REST API.

The event provides 2 parameters, ID and quantity.&nbsp;The ID belongs to the respective shopping cart&nbsp;item,&nbsp; **how do I read it out now** &nbsp;(item, quantity, price, etc.)?

There is the sBasket :: sGetBasket () function, but how do I get there from my plugin?

I also looked at the two services&nbsp;_shopware.cart.basket\_helper_&nbsp;and&nbsp;_shopware.cart.basket\_query\_helper_ **&nbsp;** , none of which return the shopping cart (by position).

_Shopware () -\> Modules () -\> Basket () -\> sGetBasket ()_ **&nbsp;** leads to an error in the event discussed, presumably because it triggers the event itself.

How do you get here?
