The SessionProperty tag is used to map session IDs between Digital Analytics and other applications.

For example, SessionProperty tags can map visitor session IDs between Tealeaf and Digital Analytics to create a segment that can be analyzed in Explore reports. When Tealeaf JavaScript is present on a page, the cmCreateSessionPropertyTag(...) function creates a SessionProperty tag, which captures the Tealeaf session IDs and the Digital Analytics IDs. When a Tealeaf user exports Tealeaf session IDs, the SessionProperty tags map the exported Tealeaf IDs to Digital Analytics IDs.

The cmCreateSessionPropertyTag(...) function definition in eluminate.js includes three parameters: session type (for example, "Tealeaf"), a session ID, and a hash value. The session type and session ID are required; the hash value is optional. There is no need to manually implement a call to the SessionProperty tag function; it is called automatically by Digital Analytics.
