External APICommunityPosts

Get published-post insights

Performance for one published post and its superpower: public/private replies, link-button clicks + CTR, reactions, comments, shares, auto-likes. Covers up to the last 365 days; older posts come back with `isOldPost=true` and empty funnel metrics. `mediumId` is **required**.

Export a post's stored comments to CSV

Export a post's **stored** comments to a CSV and return `{ totalCount, csvUrl }`. When there are no stored comments, `csvUrl` is `null` and `totalCount` is `0`. `mediumId` is **required**.
