Hi,

I am trying to develop S2S integration using canvas application. For that i followed http://www.jitendrazaa.com/blog/salesforce/salesforce-to-salesforce-integration-using-canvas/ In that he asked to develop a VF(in service provider) which will be called in identity provider. 

VF code is as below

<apex:page showHeader="false">
    
    <script type="text/javascript" src="{!URLFOR($Resource.CanvasSDK,'SalesforceCanvasJavascriptSDK-master/js/canvas-all.js')}" />
    
    <script type="text/javascript">
        
        var sid="{!GETSESSIONID()}".substr(1,30) +'...';
    
    	function refreshSR(){
        	Sfdc.canvas.client.refreshSignedRequest(function(data){
            	
                if(data.status == 200){
                	var signedRequest = data.payload.response;
                    var part = signedRequest.split('.')[1];
                    var obj = JSON.parse(Sfdc.canvas.decode(part));
                    updateDisplay(obj) ;
                } 
            }); 
        }
    
    function updateDisplay(obj){
    	setValue('spSessionId', sid);
        setValue('ipOAuth', obj.client.oauthToken.substr(1,30)+'...');
        setValue('ipUser', obj.context.user.fullName);
        setValue('ipOrg', obj.context.organization.name);
        setValue('ipRefresh', obj.client.refreshToken.substr(1,30)+'...');
    }
    
    function setValue(eleId,val)
    {
       	var domEl = document.getElementById(eleId);
        if(domEl){
        	domEl.innerHTML = val;    
        }
    }
    
    Sfdc.canvas.onReady(function(){
    	refreshSR();
    });
         
    </script>
          
        <b> <u> Service Provider Org </u></b>
