This article will provide you with instructions on how to pass the AppNexus SSP data variable managed by either the DoubleClick Campaign Manager or the Sizmek ad server.

DoubleClick Campaign Manager

Step 1: Modifying the placement

Firstly, you will have to build the DoubleClick campaign, placements, creatives and the ads for your campaign. Once this is finished, return to the placement section and click into the placements you would like to update the URL for. 

Click into the "Tag Defaults" subsection and define the "Additional key-values". In this case you will have to copy the following into the "Additional key-values": SSP_DATA=${SSP_DATA} 

Once the placement tag is loaded, the key value will populate as the following: SSP_DATA=asb165464654

Step 2: Modifying the ad

Once Step 1 has been finished, navigate to the ads section. Select the ad associated with the placement(s) you have edited. Under "Creative assignments" you can define landing page as custom landing page and copy the following at the end of the URL: ?sspdata=%pSSP_DATA=!; 

Sizmek

Step 1: Modifying the placement

Navigate to the "Placements Tags" section and define the "Line ID". In this case you will have to copy the following into "Line ID": ${SSP_DATA}

When the placement tag is loaded, the "Line ID" will populate as the following: asb165464654

Step 2: Modifying the ad

Once Step 1 has been finished, navigate to the "Click-Thru URL" section. Here you will have to update the end of the URL with the following:
