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.

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

Thanks,
