Managing Work Logs for Others via the API
Log work on behalf of others using the Jira REST API.
A work log is always attributed to its native Jira author, so logging work for someone else means sending the create request on behalf of that user's account. Jira does not let you set the author in the request body, so to attribute a work log to another user via the API you send the request through impersonation, as that account. Atlassian supports several ways to do this; see the relevant Atlassian developer documentation for the option that fits your integration.
