List of genres (categories) on iTunes/the App Store

[baltpeter]

We need a list of all the possible categories (Apple internally calls them "genres") on the App Store.

This one's easy: https://itunes.apple.com/WebObjects/MZStoreServices.woa/ws/genres has a full list.

We are interested in first-level category 36 (App Store). The grab a list of all second-level subcategories (there are also third-level categories but only for "Games", "Magazines & Newspapers", "Stickers") :

const genreJson = await fetch('https://itunes.apple.com/WebObjects/MZStoreServices.woa/ws/genres').then((r) =>
    r.json()
);

const appsGenres = genreJson[36];
if (appsGenres.name !== 'App Store') throw new Error('Unexpected API response.');

const subgenres = Object.values(appsGenres.subgenres).reduce((acc, cur) => ({ ...acc, [cur.name]: +cur.id }), {});
subgenres.all = 36;
console.log(subgenres);

That yields:
