Error al consumir DIAN web service

Question

estoy haciendo un protocolo de comunicación para consumir el web service de la dian , pero cada que envio el soap request me devuelve un 400 bad request, antes me daba un 500 "no se pudo verificar la seguridad del mensaje" le arreglé unas cosas de la firma digital y ya no me sale ese error aunque la firma digital no se crea dentro del nodo correcto en el formato xml parece que si detecte la firma el servidor de la dian y la procesa
