I need to update all the opportunities in my sandbox to test the bulk capability of sending the information to our custom portal via an HTTP Call Out.

Individually it works fine. However when I did a bulk update of 2800+ opportunities via DemandTools, only a hand full went over to our portal. My callout receives a set of IDs from a trigger (which is also bulkified I think). It should then process all of these IDs.

Anyone know if my trigger or callout is flawed or if it was a Salesforce limit hit?

Trigger

trigger CustomPortalOpp on Opportunity (after insert, after update) {
    
List<opportunity> oppList =  new List<opportunity>();

//prevents an infinite loop
if(Recursion.objectRecursion)
    return;
Recursion.objectRecursion = TRUE;

//Create list of opportunity
List<opportunity> opp_list = [SELECT Id, AccountId, Account_Manager_ID__c,  Client_Total__c, Event_Address__c,
                              Event_Consultant__c, Event_Date__c, Event_Start_Time__c, Event_End_Time__c,
                              Event_Status__c, Event_Type__c, Invite_Custom_Fields__c,
                              Invite_Headline__c, Invite_Request_Form__c, Invite_Yes_Limit__c,
                              Market__c, Name, Send_from_Email__c, Send_from_Name__c,
                              SG_Invite_ID__c, StageName, Time_Zone__c, Venue_Name__c FROM Opportunity WHERE Id IN: Trigger.newmap.keyset()];

   for (Opportunity o : opp_list) {
            opplist.add(o);
    }
    
    Set<Id> opptyIds = (new Map<Id,Opportunity>(oppList)).keySet();
    
    //process updates
    if (opp_list.isEmpty()==FALSE){
        
        if(!Test.isRunningTest()){
               IF(System.IsBatch() == false && System.isFuture() == false){ 
                    MySforceHttpCallOut.putDataToRemote_Opportunity(opptyIds); //call a method with @future annotation

               }

    }  
    
}
}
