The below install instructions do not match the current version magento (126.96.36.199). 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 188.8.131.52?
