Change in Payment Method Notification

I am trying to have a notification emailed when the user adds a payment method in their account area. I have a function that is up and working to notify of any changes to their username or and billing or shipping address fields but I can not find the hook to add for payment updates. Here is what I have tried (just the sample of complete):

add_action(‘woocommerce_add_payment_method’, array( $this, ‘woocommerce_send_notification’ ));

replaced woocommerce_add_payment_method with the following too:
pay_action
add_payment_method_action
delete_payment_method_action
set_default_payment_method_action
woocommerce_delete_payment_method
woocommerce_set_default_payment_method

I have searched through docs and and looked at all the hooks on woocommerce.com

Hlep please:)
