Stripe payment integration in controller action

How would you do for that action would execute if the stripe payment is performing

My action controller:

def create
    @action = Action.new(action_params)
    @action.user = current_user
    if @action.save
         redirect_to new_charge_path
    else
        render :new
    end
end

I would like my @ action.save is executed only if the payment is done.

(new_charge_path is stripe route)
