# 307 Adaptive Case Management API - Part 4- Getting the audit trail

Building on from the previous examples -

Here is the code -

    public static boolean getAudit4Case(ICaseService caseService,
                                        IBPMContext context,
                                        String caseId) throws CaseServiceException {

        CaseIdentifier caseIdentifier =
            CaseIdentifier.getCaseIdentifierBasedOnCaseId(caseId);
        System.out.println("Case identifier = " +caseIdentifier.toString());

        TEventType eventType = null;
        // event types is one of the following
        /*eventType = TEventType.ACTIVITY_EVENT;
        eventType = TEventType.DOCUMENT_EVENT;

        eventType = TEventType.ACTIVITY_EVENT;*/
        eventType = TEventType.LIFECYCLE_EVENT;
           
        int pageNum = 1;
        int pageSize = 10;
        String updatedBy = "System";
        CaseObjectsList caseObjectsList =
            caseService.getAudit(context, caseIdentifier, eventType, null,

        System.out.println("### Lifecycle Events ###");
         getAudit4CaseLifecycleEvents(persistedEvents, caseId);
