We've just added two new dimensions to the MediaMath Performance report. You now have access to Deal Name and Deal ID.
Providing you've connected the Performance report to Funnel, no action is required in order to obtain data for these dimensions going forward.
You can learn more about the fields you can obtain from MediaMath in this article.
We hope that you find these new dimensions useful! If you have any questions or if you would like to see historic data for these fields, please contact firstname.lastname@example.org and we'll be happy to help :)
