Pushing Visitor data into SalesIQ?

Pushing Visitor data into SalesIQ?

How can I push visitor data to SalesIQ? I can't see a REST method that I could use.
We have implemented a solution that tracks "offline" visitors for brick and mortar stores, I would like to push Visitor's:
  • name
  • email
  • info: key, value
    • "info" or what ever available fields to store path.
"info" would be the physical area/department (offline) visited, instead of page (online).

Thank you in advance.
