Removes products from a cart

POST 
/api/v1/eventim/cart/removeProducts

Removes a specified quantity of a product from an existing cart item. Products can be removed globally or scoped to a specific event session:

• Global products: Omit both EventId and EventSessionId. The product is removed from the cart without session filtering.
• Session-scoped products: Provide both EventId and EventSessionId. The product removal is linked to that specific event session.

EventId and EventSessionId must be provided together or both omitted. When the quantity to remove is greater than or equal to the current quantity, the cart item quantity is set to zero. The response includes the updated cart item details with pricing breakdown, including base amount (per unit) and itemized fees.
