When retrieving email engagment data via the v1 api (/engagements/v1/engagements/paged) I get back various email header data in the result meta data such as messageId, threadId, trackerKey etc.
However when I retrieve data from the v3 api (/crm/v3/objects/emails) the only data returned in the "hs_email_headers" property is sender/recipient information.
Is there any way to return additional email header information such as messageId, threadId, trackerKey etc via the v3 api?
