For Magento 1.9, I wrote an app that synchronizes selected columns from an MSSQL product database with the Magento MySQL database. The common key across the databases is a product sku.
This technique has worked great for years on Magento 1.9 and allows me to keep inventory in a brick & mortar warehouse sync'ed with the website.
The app uses a SOAP session to connect and exchange the product info ...
$soap = new SoapClient( 'http://www.mystore.com/api/?wsdl' );
$sessionId = $soap->login( $mage_user, $mage_api_key );
synchronize logic, etc.
I really don't need to re-invent this app, but I do need to connect it via magento2 SOAP. I am struggling to understand how to do this, and googling just keeps taking me deeper into a black hole of confusion.
Has anyone experience of doing this? Any templates?
Many thanks for any help / pointers.
