List reactions on a LinkedIn post

GET
/v1/posts/{postId}/reactions

Returns the individual reactions LinkedIn holds for a post published through PostZen, plus a per-type count of the returned page. LinkedIn only, and organization (company page) posts only. The post's LinkedIn connection must hold r_organization_social_feed, which LinkedIn ships with its Community Management API product — reconnect the account if it was connected before company-page posting was enabled. A personal (member) post always returns 403 personalPostUnsupported: reading a member's own comments and reactions needs r_member_social_feed, which LinkedIn grants to select developers only. Read-only and read-write API keys are accepted.

List comments on a LinkedIn post GET

Returns the comments LinkedIn holds for a post published through PostZen. LinkedIn only, and organization (company page) posts only. The post's LinkedIn connection must hold `r_organization_social_feed`, which LinkedIn ships with its Community Management API product — reconnect the account if it was connected before company-page posting was enabled. A personal (member) post always returns `403 personalPostUnsupported`: reading a member's own comments and reactions needs `r_member_social_feed`, which LinkedIn grants to select developers only. Read-only and read-write API keys are accepted.

List comments on a post GET

Returns the comments the platform holds for one Instagram, Facebook, or Threads post, and refreshes PostZen's stored copy of the thread as a side effect. `replies` carries the first page of nested replies when the platform returns them cheaply — `repliesHasMore` says when it did not, and passing that comment's id as `commentId` pages through the rest. Instagram threads are only two levels deep, so a reply never carries replies of its own. Fields a platform does not report are absent rather than zero: Threads, for example, never reports per-reply like counts. Read-only and read-write API keys are accepted.
