Expose APEXT REST Webservices to external system when records is updating(trigger)

Hello there,

I am having below requirement.

In salesforce when a record is updated then send data of that record to external system using reset API JSON file.

I have written below code but I am not sure whether I am going in right direction 

Trigger

rigger ImplementationPlanActivity on Implementation_Plan_Activity__c (after update) {

    Trigger_Settings__c triggerSettings = Trigger_Settings__c.getInstance();

    if(triggerSettings.ImplementationPlanActivity__c == false){

        return;

    }

            set<Id> IPAIdSet=new Set<Id>();

            for(Implementation_Plan_Activity__c IPArecord : trigger.new ){

                IPAIdSet.add(IPArecord .id);

            }

            IPAResetAPIClass.IPAData(IPAIdSet);

        }

    }

Webservice class

global class IPAResetAPIClass{

@future(callout=true)

    global static void IPAData(Set<Id> newIPASetId){

    

        List<Implementation_Plan_Activity__c> ipaNewList=[SELECT id,Name,

                                                                    Account_Manager__r.Name,

                                                                    Account_Manager__r.Email,

                                                                    Account_Specialist__r.Name,

                                                                    Account_Specialist__r.Email,    

                                                                    SFID18__c ,

                                                                    RecordTypeId

                                                            FROM Implementation_Plan_Activity__c where Id IN : newIPASetId];

                                                    ipaNewList[0].SFID18__c,

                                                    ipaNewList[0].RecordTypeId));

        

 

       RecordType recordTypeRecord=[Select id,Name from RecordType  where id=:ipaNewList[0].RecordTypeId limit 1];

       

       string  resource=null;

       if(recordTypeRecord.Name=='Auto Provisioning'){

           resource='Auto Provisioning';

        string JSONString=JSON.serializePretty(warpperIPAList);

        system.debug('*********serialized imp='+JSONString);

        

        string endURL;

        req.setMethod('POST');

      

        req.setHeader('content-type', 'application/json');

        //Set HTTPRequest Endpoint dummy url

        req.setEndpoint('http://requestb.in/13auzf41');

        //req.setEndpoint(endURL);

        

        //Set HTTP Request Body

        req.setBody(JSONString);

        Http http = new Http();

        try{

            HTTPResponse res = http.send(req);

            //Helpful debug messages

            System.debug(res.toString());

            System.debug('STATUS:'+res.getStatus());

            System.debug('STATUS_CODE:'+res.getStatusCode());

            System.debug('Content: ' + res.getBody());

            

            //we can create success object record

        }

        catch(Exception e){

            System.debug('******* error message='+e);

            //we can create error object record

        }

    

    }

                                        string IPASFDCId,

                                        string IPARecordTypeId){

            this.IPAId=IPAId;

            this.IPAName=IPAName;

            this.IPAAccManagerName=IPAAccManagerName;

            this.IPAAccManagerEmail=IPAAccManagerEmail;

    The basic Idea of calling a @future method to send the data seems to be the correct approach for this requirement.  As long as other code is developed properly in this instance, and doesn't call updates on Implementation_Plan_Activity__c in a loop - you should be fine.  Otherwise that type of code (other than being badly written) may cause you to exceed your limit of 50 future invocations in a single context.
