Explanation: If your advertiser already uses Campaign Manager to serve ads, you can link an existing Campaign Manager advertiser to a new advertiser in Display & Video 360. You can link any Campaign Manager advertiser to a new advertiser in Display & Video provided that you’ve been given permission to add the advertiser from Campaign Manager. Before you can link to a Campaign Manager advertiser in Display & Video 360, your advertiser has to share their Floodlight configuration with your Display & Video 360 partner. To associate a Display & Video 360 partner with your Floodlight configuration:
- Select an advertiser from the Advertisers tab and click Floodlight configuration.
- Expand the Display & Video 360 association section, and click New association.
- Read and authorize the information sharing notice.
- Enter the Display & Video 360 partner ID you want to link to. Your Display & Video 360 partner must authorize the association then select the appropriate Floodlight configuration for use.
