Is there an exact hook for cart update events? PS 1.6

[mikhrock]

I need to detect the exact moments of cart update - when a product is added/removed, quantity changed etc.

 

I'm currently using 'actionCartSave', but it fires too often - for example, when a product page is just viewed and nothing really happens to the cart. The $params['cart'] can obviously be empty in this case, which leads to errors in my module.

 

Please share any ideas on how I can detect only the cart update events, or probably where I'm wrong in using actionCartSave hook.

 

Thank you

Ok, for now I've managed to solve the problem by manually detecting and checking the places where Cart Save is called and not needed (these are AuthController and AddressController for example).

 

But the question is still open, I hope there is a more efficient and good looking way.
