Post Data to A Web Service Using REST

Hi

I have a requirement: My Salesforce org should send data to a web service whenever the status (field) of the tenant (object) changes from active to non-active.

The message that I post should contain the ID of the Tenant that not active anymore. I can't figure out how to add the ID of this tenant.

Please help me resolve this puzzle.

This is my code:

global class FOBCallouts1{

@Future (Callout=true)

public static void tenantUpdate(list<tenant__c> TenList, map <id,tenant__c> oldMap)

{ // list<tenant__c> TenList=new list<tenant__c>();

// map <id,tenant__c> oldMap=new map<id, tenant__c>(); for(tenant__c objten:TenList)

{ if(objten.status__c=='Non-active' && oldMap.get(objten.Id).status__c =='Active'){ Http http = new Http();

HttpRequest request = new HttpRequest(); request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals');

request.setMethod('POST');

Tenant__c tenant=[SELECT Id FROM Tenant__c]; 

String JsonString=JSON.serialize(objten.id);

String body = 'Please deactivate FOB for following tenants(ID)'; request.setBody(body+JsonString); System.debug(request.getBody()); } } } }

    Hi,

    This is one way to get the user Id.

    /*

    global class FOBCallouts1{

        // Global variable declaration

        Private static final String TAG = 'TAG-FOBCallouts1 :: ';

        private static String status = 'Non-active';

        

        //== Method to validate the Tenant status

        public static void tenantUpdate(list<tenant__c> TenList, map <id,tenant__c> oldMap) { 

            

            Set<String> nameSet = new Set<String>();

            Set<Id> userIdSet     = new Set<Id>();

            

            // Loop to iterate over the list of tenants

            for(tenant__c objten : tenList) {

                // Condition to verify the Status of the tenant

                if(oldMap.get(objten.Id).Status__c != objten.Status__c && status.equalsIgnoreCase(objten.Status__c)) {

                    nameSet.add(objten.Name__c);

                }

            }// END FOR

            System.debug(TAG + 'Name Set size : ' +nameSet.size());

            

            // Condition to check for the name set

            if(nameSet != null && nameSet.size() > 0) {

                // Query to fetch the User details

                List<User> users = [SELECT ID, Name FROM User WHERE Name = : nameSet];

                System.debug(TAG + 'User List size : ' +users.size());

                

                // Condition to check for the user details

                if(users != null && users.size() > 0) {

                    

                    // Loop to iterate over the List of users

                    for(User user : users) {

                        userIdSet.add(user.Id);

                    }// END FOR

                    System.debug(TAG + 'User Id Set Size : ' +userIdSet.size());

                }// END IF

                

                // Condition to check for the User Id set

                if(userIdSet != null && userIdSet.size() > 0) {

                    FOBCallouts1.doCallout(userIdSet);

                }

            }

            

        }

        

        @future(callout = true)

        private static void doCallout(Set<Id> userIds) {

            

            // Loop to iterate over the User Id's

            for(Id userId : userIds) {

                // Callouts

                Http http = new Http();

                HttpRequest request = new HttpRequest();

                request.setEndpoint('https://th-apex-http-callout.herokuapp.com/animals');

                request.setMethod('POST');

                String JsonString=JSON.serialize(userId);

                String body = 'Please deactivate FOB for following tenants(ID)';

                request.setBody(body+JsonString);

                System.debug(TAG + 'Verifying the request body : ' +request.getBody());

                

            }// END FOR

        }

    }

    1. I created a name custom field and used it against the User object to get the User Id. I hope this helps.

    Thanks,

    Prakash. J
