IAB Category API for iOS Apps

Return the default Apple App Store category and IAB category for iOS apps.

With the IAB Category API you can obtain the developer website for each app to support the upcoming Authorized Sellers for Apps (app-ads.txt) Specification. The specification is designed to protect mobile app ad inventory by allowing apps to list authorized sellers of their app’s ad inventory on their developer website.

The Advanced Query API allows to filter by IAB categories, starting from Professional plan or higher.
