Api to detect issue sprint assign unassign

Hi,
does the zenhub rest or graphql api have a means to get the event/time when an issue was assigned to a sprint and if it was removed from a sprint? I am doing some analysis on team’s issues worked on and when we decided an issue had to be removed from a sprint.

Found it. I can get “__typename”: “TimelineItem”,
“type”: “issue.remove_from_sprint”,
from this zenhub graphql query

query getTimelineItems($repositoryGhId: Int!, $issueNumber: Int!) {
  issueByInfo(repositoryGhId: $repositoryGhId, issueNumber: $issueNumber) {
    
		state
		title
		createdAt
		closedAt
		estimate {
			value
		}
		number
		repository {
			ghId
		}
    timelineItems(first: 50) {
      nodes {
				__typename
        type: key
        id
        data
        createdAt
      }
    }
  }
}
