Deprecated: use Fetch Post Activities V2 (POST /v2/posts) instead. It returns every comment of a post (this endpoint reads LinkedIn's filtered view and can miss comments), keeps totalElements stable between pages, and adds sort orders, a reaction type filter and the replies of a comment.

This endpoint retrieves comments or reactions associated with a post, based on the post URN.

The header Content-Type: application/json must be included in the request.
