Thanks for the responce!

I have already tried that, but the Offset is 0.

Here is the snippet for reference, Let me know if there is any issue in this code.

MktMktowsApiService service = new MktMktowsApiService(marketoSoapEndPoint, serviceName);

            MktowsPort port = service.getMktowsApiSoapPort();

        DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");

            String text = df.format(new Date());

            String requestTimestamp = text.substring(0, 22) + ":" + text.substring(22);         

            String encryptString = requestTimestamp + marketoUserId ;

            SecretKeySpec secretKey = new SecretKeySpec(marketoSecretKey.getBytes(), "HmacSHA1");

            Mac mac = Mac.getInstance("HmacSHA1");

            mac.init(secretKey);

            byte[] rawHmac = mac.doFinal(encryptString.getBytes());

            char[] hexChars = Hex.encodeHex(rawHmac);

            String signature = new String(hexChars);

            AuthenticationHeader header = new AuthenticationHeader();

            header.setMktowsUserId(marketoUserId);

            header.setRequestTimestamp(requestTimestamp);

            header.setRequestSignature(signature);

            ParamsGetLeadActivity request = new ParamsGetLeadActivity();

            LeadKey key = new LeadKey();

            key.setKeyType(LeadKeyRef.EMAIL);

            key.setKeyValue("t@t.com");

            request.setLeadKey(key);

            ObjectFactory objectFactory = new ObjectFactory();

            JAXBElement<Integer> batchSize = objectFactory.createParamsGetLeadActivityBatchSize(10);

            request.setBatchSize(batchSize);

            ActivityTypeFilter atv = new ActivityTypeFilter();

            ArrayOfActivityType aatt = new ArrayOfActivityType();

            aatt.getActivityTypes().add(ActivityType.UNSUBSCRIBE_EMAIL);

            atv.setIncludeTypes(aatt);

            JAXBElement<ActivityTypeFilter> typeFilter = objectFactory.createParamsGetLeadActivityActivityFilter(atv);

            request.setActivityFilter(typeFilter);

            SuccessGetLeadActivity result = port.getLeadActivity(request, header);

            JAXBContext context = JAXBContext.newInstance(SuccessGetLeadActivity.class);

            Marshaller m = context.createMarshaller();

            m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

            m.marshal(result, System.out);
