Reload checkout step if a voucher is applied

[kubilayrd]

I am trying to integrate a 3rd party taxing module into my shop (PS version 1.7.6.4) and since I am unable to hook voucher applied, the price is calculated incorrectly if a voucher is applied at the last step of the checkout. I simply need to reload the checkout step if a voucher is applied/removed at the last step of the checkout (payment details step).

I was unable to find the most proper place for this. Should I look for `updateCart` event or is there more straightforward place to plug this code in?

Hello, in this scenario you can used the hook ActionCartSave and perform action base on params variable

function hookActionCartSave($params)

like id_card, id_product, discount_name etc
