The below install instructions do not match the current version magento (220.127.116.11). I think some of the names have changed:
Catalog->Product->Product Details - doesn't exist
Catalog->Category->Get Category Tree - is this "Retrieve Categories Tree?"
Catalog->Category->Get Category Details - doesn't exist
Catalog->Category->Assigned Products -
any updated instructions for Magento 18.104.22.168?
