The Vidyard for Marketo integration is designed to send video view information from Vidyard players into Marketo Contacts.
You may have other plugins or software that is also connected to Marketo that makes use of the data we pass through.
It's not possible for Vidyard to know what happens to the data once it is in the Marketo system. We can only provide a mechanism to push and pull data directly to Marketo through their API.
The Marketo support team may be able to provide more insight into where else the data could be going by looking at their data logs.
