Apple lists API that require declared reasons to use

Apple will now require developers to declare use of specific APIs with app's privacy manifest.

Starting in fall 2023, when you upload a new app or app update to App Store Connect that uses an API (including from third-party SDKs) that requires a reason, you’ll receive a notice if you haven’t provided an approved reason in your app’s privacy manifest. And starting in spring 2024, in order to upload your new app or app update to App Store Connect, you’ll be required to include an approved reason in the app’s privacy manifest which accurately reflects how your app uses the API.
