A bulk request returns data you can use with the different headers in the Update, Create, Estimate, and Delete worksheets.
The Request worksheet does not have its own set of column headers and you don't need to copy IDs to any of the columns. Instead, it returns data based on the action button you click in the toolbar. And, an optional reporting feature returns a frequency count for pixel fires and unique user count for several fixed time intervals.
To make bulk requests, open the Bulk Management Tools worksheet and:
The Audience Manager API writes bulk data back to the Request worksheet.
If your bulk update returns an error or fails, see Troubleshooting Tips for Bulk Management Tools.
