Fields #

Field	Type	Notes
`urn`	string	The activity's numeric id, with the urn:li:activity: prefix stripped - the id, not the full urn. Reconstruct it yourself as urn:li:activity:<id> if you need the prefixed form, or pass the bare id to posts/enrich for the full record.
`url`	string
`text`	string
`author_name`	string
`author_url`	string
`author_headline`	string
`posted_at`	string (RFC 3339)	Decoded from the activity id, which encodes a Unix millisecond timestamp in its top bits, because the feed carries no timestamp field of its own. Absent when the date could not be decoded, rather than present and wrong.
`reaction_count`	integer
`comment_count`	integer
`repost_count`	integer

Absent is not null: a field we did not get is omitted rather than sent as an empty string, so you can tell "LinkedIn does not have this" from "this person left it blank".
