Magento 1.9 I used the WSDL 

> [https://github.com/marouanbmm/magento-Apis/blob/master/code/local/Tecnifibre/SerienFlow/etc/wsdl.xml][1]

file as part of my development `Delphi win 32` to have access to the functions, arrays, objects etc... This was very helpful.

Actually I need to customize this module to use into `Magento 2`, so I must
use wsdl file in `Magento 2`. 

Can anyone enlighten me ?
