i want to get list of category and subcategory (name of category) in magento , i use this API : catalogCategoryInfo (SOAP V2) . i try to get Names of direct child categories but it return id of direct child ! my question is how can i get name of category child ? API Link
catalogCategoryInfo method returns full information about one category. But ids are the only information about its child categories.
Try to use
catalogCategoryTree method instead. It will return you category information tree, with all children names.
