The /categories.json API call returns only top-level categories, at least on my server. I can read subcategories using /c/<id>.json but I don’t know how to discover those IDs.

To get all categories and subcategories from the API, you need to make a request to /site.json. If you don’t mind looking at PHP/WordPress code, there’s an example API request to get all categories here: wp-discourse/lib/plugin-utilities.php at main · discourse/wp-discourse · GitHub .

Terrific, thank you! I notice that the category record returned doesn’t have a parent category. If it did, a flattened list from /catgories.json of all categories would be I think a less-surprising result, as opposed to only the root level.

I see that subs have parent_category_id from sites.json. I wonder why then categories.json is only root level.

なお、/categories.json?include_subcategories=trueでcategories.jsonからすべてのカテゴリとサブカテゴリを取得できるようになりました。
