Returns the paginated history of contact voice authentication activities for the account, such as authentication attempts and other identity-related events captured during calls.
Use this endpoint to power dashboards, audit views or reporting flows that need a chronological feed of identity activity for contacts in the account.

The list is paginated and the maximum page size is 250 items, so larger exports must use the CSV-producing variant of this endpoint instead.
When the contact query parameter is true (the default), activity entries are enriched with the matching contact's name and id resolved from the phone number; setting it to false skips that lookup and returns the raw activity records.
