properties

A string map of event-specific data that you might choose to record. For example, if a user takes an action, other than the action ID, you might also send the number of actions taken by the user.

Each item in the map consists of a key-value pair. For example,

{"numberOfActions": "12"}

The keys use camel case names that match the fields in the Action interactions schema. In the above example, the numberOfActions would match the 'NUMBER_OF_ACTIONS' field defined in the Action interactions schema.

The following can't be included as a keyword for properties (case insensitive).

• userId

• sessionId

• eventType

• timestamp

• recommendationId

• impression
