Thanks BDatla,

you were correct. aftert his step i try to call this class from a batchable class and run this batch apex with a scheduler. 

when i am running the scheduler i am not getting any error and getting success but the problem is the end point which i am using is intranet and it is not exposed publically so i should be getting an error saying refused or some thing like this but it is not happning so and in debug log i can see that number of callouts is 0 outoff 0 that neams a callout has not been made right ?? can you check my code if what i am doing is correct Please 

My Batch class 

global class QueryCampaignMembers implements Database.Batchable<sobject>,Database.AllowsCallouts{
string QueryString = 'SELECT Id FROM CampaignMember WHERE CV_ActiveForContact__c = TRUE AND (CV_Processado__c = FALSE OR CV_Processado__c = NULL)';    
   global QueryCampaignMembers(){       
    }
    global Database.QueryLocator start(Database.BatchableContext BC){
        return Database.getQueryLocator(QueryString);
    }
    global void execute(Database.BatchableContext BC,List<sobject> members){
        try{
            system.debug('Members : ' + members);
            Set<string> myMemberIDs = new Set<string>();
            for(sobject s : members){
                s.put('CV_Processado__c',TRUE);
                myMemberIDs.add(string.valueOf(s.get('Id'))); 
            }           
            update members;
            system.debug('Campaign ID Set : ' + myMemberIDs);
            string myIds = '';
            for(string myID:myMemberIDs){
                myIds += myID + ',';
            }
            system.debug('myIds : ' + myIds);
            if(null != myIDs){
                    AsyncVerisysComBr verisys = new AsyncVerisysComBr();
                    AsyncVerisysComBr.AsyncWebService1Soap asyncWS = new AsyncVerisysComBr.AsyncWebService1Soap();
                
            }
        }
        catch(Exception ex){
            System.debug('Exception Occurred : ' + ex.getMessage() +'\n @ : '+ ex.getLineNumber());
        }
    }
     global void finish(Database.BatchableContext BC){
    }
}

Scheduler class : 

global class QueryCampaignMembers_schedule implements Schedulable {
    global void execute(SchedulableContext scMain) {
        QueryCampaignMembers clsQueryCampaignMembers = new QueryCampaignMembers();
        ID idBatch = Database.executeBatch(clsQueryCampaignMembers, 200);
    }
}

Debug log : 
Number of callouts: 0 out of 0

Please help me if i am calling it right or not
