150 For technical reasons an advice can be declined if PayEx is unable to store the transaction. In this case the third party host need to retry the advice until manual intervention or the advice has been accepted. It’s expected that the third party implement a retry delay (to-be-defined). After 6 retry attemps have failed manual intervention by thirsd party and PayEx support must be initiated.
