Substack Category IDs

Category IDs and slugs for the category parameter on Category Publications and Category Feed. Substack has 33 leaderboard categories; each has a top board and a paid board of up to 525 publications and a rising board of up to 250. The 210 subcategories below appear in publication data but have no leaderboards. Either the numeric ID or the slug works. Two site-wide boards take a name instead: bestsellers (New Bestsellers, a rising list) and podcasts (Podcast Bestsellers).
