Google Analytics data export API does not support exporting visitor IDs and hit timestamps. To export these data, additional custom dimensions are needed to track such data for exporting purposes.
The table below shows the custom dimensions needed for SkyGlue raw data export.
You can use any custom dimensions available to store the above attributes. The details for setting up custom dimensions in Google Analytics is here. After setting up the custom dimensions, please email the indexes of the custom dimensions to firstname.lastname@example.org along with your account login name.
