Overview:
ART19 can support 3rd party measurement tags from Advertisecast. As with all 3rd party measurement URL’s, Advertisecast measurement can be added at both the campaign or ad level. A measurement URL configured at the campaign level will fire for every ad associated with the campaign. This saves you time if you have multiple pieces of creative requiring the same measurement URL.
Step 1: Advertisecast Campaign Level Measurement
Navigate to the campaign details page and scroll to the bottom to find 3rd Party Campaign Measurement.
To add a destination, press the blue plus button and provide a name for your new measurement destination. Then click save. Please note, a Measurement Destination can be called whatever you choose but we recommend using a name that includes the 3rd party vendor.
Step 2: Apply measurement URL
Click on the pencil icon on the top-right of the card to populate the remainder of your measurement destination information. 
A typical Advertisecast tag will look like this:
https://advertisecast.com/t/12345
There are no additional macros needed for Advertisecast at this time. Simply copy the URL provided as is into the URL field, set to Active and hit Update & Close.
