Team and I are supporting a privacy project and ask was to see what data is going out to what vendors. A support ticket was opened. We limited the request down to just data feeds in not getting a reply. Ticket was escalated and engineering followed up with "From our back-end we don't record the headers per data feed ID.
Best thing to do would be to have an admin review these feeds from Analytics UI -> Admin -> Data Feed to get this information"
We know the data is available through the UI, but a programmatic way to get all this data is needed.
