# OCAPI Cross Device Activity Tracking

OCAPI supports correlating data across devices for guests and logged in customers, which applies to both client and server side activities.

How:

Client side activities use the `visit_id` as an identifier for guest users. After the user logs in, use a combination of `hashed_login + visit_id`.

Server side activities Use the `visit_id` as an identifier for guest users. After the user logs in, use a combination of `hashed_login + visit_id`.
