I wanted to confirm with the group something about the Marketo Rest API.
I have need to pull the Anonymous leads who visited a page over a certain time period. I am able to get the Lead ID from the web page activity report. What I would like to do with that ID is pull additional data such as activity or even the Cookie ID.
I have been unsuccessful up to this point and wanted to validate this is due to the Rest API not being able to pull Anonymous lead data.
If someone could let me know it is possible or confirm my findings, I would be very happy.
You're correct. Marketo isn't the place to report on anonymous sessions while they're still anonymous. It's for web sessions that are associated with named leads (even if some activity took place while the lead was unknown).
