Identity Resolution | Tealium for Android (Kotlin) |Tealium Developer Docs

How it Works

The Tealium Kotlin library generates a unique persistent visitor ID the first time it is launched and stores it in tealium.visitorId. This value is included in each tracked event as the attribute tealium_visitor_id. This value is the primary visitor ID used in Tealium AudienceStream. Add secondary visitor ID attributes to the data layer as needed.

class TealiumHelper {
	lateinit var tealium: Tealium
    // ... init `tealium`

    // Retrieve Tealium first party visitor ID, if needed
    fun getVisitorId(): String {
        return tealium.visitorId
    }

    // adds a known visitor ID (such as an email address) to dataLayer
    fun setKnownVisitorId(id: String) {
        tealium.dataLayer.putString("customer_id", id, Expiry.FOREVER)
    }
}
