LinkedIn Comments — Comment & Post Timestamps Now Populated

⚠️ Breaking — new timestamp fields added, previously-null field now populated.

LinkedIn Comments (contact) signals now include actual posting timestamps. Previously, detected_at (when Autobound ingested the signal, typically 1-3 weeks after posting) was the only time reference.

New & Updated Fields

Field	Type	Change	Description
`data.comment_posted_at`	string (ISO 8601)	New	When the comment was actually posted on LinkedIn
`data.parent_post.posted_date`	string (ISO 8601)	Now populated	When the parent post was published (field existed but was always null)

Example

{
  "data": {
    "comment_posted_at": "2026-04-27T00:03:51.002Z",
    "parent_post": {
      "posted_date": "2026-04-24T00:21:40.232Z"
    }
  }
}

All other fields unchanged. View full schema →

Effective: May 12, 2026 delivery onward (autobound-linkedin-comments-contact-v2 bucket).

Action required: If you filter on posted_date IS NULL or parse posted_date as a date-only string, update your logic. The field is now a full ISO 8601 datetime with milliseconds.
