Personalization keys allow the application to define certain input parameter values that differ (are personalized) from each mobile user.
The Personalization APIs allow you to manage personalization keys, and get and set personalization key values.
Type of Personalization Keys
There are three types of personalization keys: client, server, and transient (or session). Client personalization keys are persisted in the local database. Server personalization keys are persisted on the Unwired Server. Session personalization keys are not persisted and are lost after the device application terminates.
