Assign categories to iOS apps via API (or MySQL)

New Contributor III

Is anyone aware of an API method for quickly assigning categories to iOS apps? The process in the web interface is super cumbersome (although I've made it a tiny bit less so by writing this Greasemonkey/Tampermonkey script ) and it'd be nice to be able to quickly throw apps into categories when that's the only thing I need to change. Alternately, a quicky-and-dirty MySQL command would be okay, if anyone's reverse-engineered the database structure for category-app relationships.
