Upgrade to Artisan 2.3.1 -- we no longer require the GET_TASKS permission and there's a new 3rd party dependency for http uploads.
Use the new ArtisanPurchaseWorkflowManager API, which has added fields for category, subCategory and subSubCategory for all product-related API calls. These categories will be passed along with the analytics events and will be available for filtering, grouping and sorting on the Artisan Tools Analytics reports.
