Segment export: Google Ad Manager

Prerequisite for implementation of Google Ad Manager (contact Meiro team to discuss details):

Locate and submit your network code. Find your network code in Ad Manager under Admin and then Global settings and then Network code. Ensure that you've created an active first-party audience segment with which you want to associate the identifiers. If you don't want this segment to collect users using your own inventory, mark the Audience pixel segment option. Expect to wait up for 24 hours from the time of segment creation  to the time when you can perform batch upload.
Create a Google Group that contains all Google Accounts that will have access to upload and view files. (link to link to Google documentation).
