Delete Substack comment
Input
url requiredFull URL of the Substack post the comment is on, e.g. https://example.substack.com/p/my-post-slug. Many publications are served from their own domain rather than *.substack.com; those may be refused, because the signed-in Substack session is not known to reach a publication's own domain.
commentId requiredThe comment's id, from post_comment's output or get_post_comments
Output
url requireddeleted requiredTrue once Substack's own delete call has answered 200. The script fails rather than returning false, so a returned record always means the comment is gone.
commentId requiredList Substack newsletter posts
List a Substack publication's posts from its archive, newest or top first, with optional keyword search and pagination. Returns each post's title, slug, publish date, paywall status, and reaction/comment/restack counts.
Post Substack comment
Post a comment on a Substack post as the logged-in account. The account needs a display name set up on Substack first (via any post's comment box) — the script fails loudly with instructions if it isn't.
