latestOpenAPI 3.0.12026-07-22120163333.7 KBSystem Logs
Returns system-event timeline entries for the lead, sorted by timelineTime descending (newest first), with offset-based pagination.
Only system / change-log activity events are returned (e.g. stage changes, assignment/routing, subscriptions, smart-plan tasks). Call, text, email and site-activity (search / view / favorite) entries are NOT included, nor is note content (e.g. adding a note); edit/delete-note actions (types 17/18) are included. Each entry includes both the timelineType integer and a human-readable timelineTypeDesc name, so you do not need to map the integer yourself.
Note: startTime/endTime query parameters are epoch milliseconds, but the timelineTime/createTime/updateTime fields in the response are ISO-8601 strings.
Authorization: the authenticated user must be the lead's owner or the shared agent; otherwise 403 is returned.

Inclusive lower bound (milliseconds since Unix epoch, UTC).
