Things to keep in mind while developing the Salesforce App-exchange Application

In this post, I will discuss what are the important parameters that need to be taken care while developing the App-Exchange Application using Salesforce. Before we dive into the concepts I would like to tell you that after developing the application, every application goes with the below security checks

  1. Checkmarx: – It is a free tool available to scan the Complete Code that is in your org where development has been done.
  2. Security Review: – The second step after submitting the code to the checkmarx and resolving all the issues is to Submit the package for the security review where salesforce representatives check the Quality of the code and functionality as well.

So, In order to develop the application which is secure and minimize the risk of data compromise or any other confidential information a developer must need to keep the following points into the mind while developing the application

1Cross-Site Scripting 
2S(O)QL Injection 
3Cross Site Request Forgery 
4Secure Communications and Cookies 
5Storing Secrets 
6Arbitrary Redirects 
7Access Control 
8Lightning Security Best Practices 
9Marketing Cloud App Security
10Secure PostMessage
11Secure WebSockets

Here is a Link to Trailhead module which explains everything about secure coding guidelines with the practical example

How to Call Salesforce API from Lightning Component

You may have heard about that we can not make the Salesforce API Call directly from the lightning component. If you do make the callout from the lightning component then you will get the below error

INVALID_SESSION_ID:This session is not valid for use with the API.

For Example when you will execute the below code from the Developer Console then you will get the Valid Response

HTTP h = new HTTP();
HTTPRequest req = new HTTPRequest();
HttpResponse resp = new HttpResponse();

req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionId());
req.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm() + '/services/data/v41.0/query?q=Select+Id,+Name+From+Account');
resp = h.send(req);
System.debug('#### Response Status '+resp.getStatus());
System.debug('#### Response Status Code '+resp.getStatusCOde());

But if you will call the same block from the Lightning Component then you will get INVALID_SESSION_ID:This session is not valid for use with the API. Error.

I gone through with this error and found THIS SALESFORCE DOCUMENT where they have specified why we can not make API Call from JavaScript Code.

After reading the document, I have come up with 2 Solutions that are given below: –

1 – Connected App and Named Credentials as Callout Endpoints and Auth Providers

2 – Using VF Page – VF page will be used to get the Session Id of the current log in user and this VF page will be used into Apex class for fetching the Session Id.

In this tutorial we will use VF page for making callout because it is an easy and simple method method. Follow the below steps

Step1 – Open Developer Console, File -> New -> VisualForce Page -> Enter Name “GetSessionIdVF” -> OK. Use below code for VF Page

<apex:page >

Step2 – Create a New Class which will use this VF page to get the Session Id and making API Call Out. File -> New -> Apex Class -> Name it “ApiCallLightningComponent” -> OK. Use below code for the class.

public class ApiCallLightningComponent {
 * @Name : - fetchUserSessionId
 * @Description: - Call the VF page and get the Log In Use Session Id
 * @Params : - none
 * @ReturnType : - String
 public static String fetchUserSessionId(){
 String sessionId = '';
 // Refer to the Page
 PageReference reportPage = Page.GetSessionIdVF;
 // Get the content of the VF page
 String vfContent = reportPage.getContent().toString();
 System.debug('vfContent '+vfContent);
 // Find the position of Start_Of_Session_Id and End_Of_Session_Id
 Integer startP = vfContent.indexOf('Start_Of_Session_Id') + 'Start_Of_Session_Id'.length(),
 endP = vfContent.indexOf('End_Of_Session_Id');
 // Get the Session Id
 sessionId = vfContent.substring(startP, endP);
 System.debug('sessionId '+sessionId);
 // Return Session Id
 return sessionId;
 * @Name - makeAPICall
 * @Description - Responsible for making API Call out
 * @params - None
 * @ReturnType - String
 public static String makeAPICall(){
 String sessionId = fetchUserSessionId();
 HTTP h = new HTTP();
 HTTPRequest req = new HTTPRequest();
 HttpResponse resp = new HttpResponse();
 req.setHeader('Authorization', 'Bearer ' + sessionId);
 req.setEndpoint(URL.getSalesforceBaseUrl().toExternalForm() + '/services/data/v41.0/query?q=Select+Id,+Name+From+Account');
 resp = h.send(req);
 System.debug('#### Response Status '+resp.getStatus());
 System.debug('#### Response Status Code '+resp.getStatusCOde());
 return JSON.serialize(resp.getBody());

See the comments.

ApiCallLightningComponent class contains 2 methods fetchUserSessionId and makeAPICall, One for getting the Session Id and Other for making the Callout that will be called from the JavaScript.

Step3 – Create a lightning component, File -> New -> Lightning Component -> Name it “MakiAPICall” -> OK. Use below code for the Component

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes, flexipage:availableForRecordHome,force:hasRecordId, forceCommunity:availableForAllPageTypes, force:lightningQuickAction" controller="ApiCallLightningComponent" access="global" >
<div class="slds-m-around_x-small">
			<lightning:button variant="brand" label="Make CallOut" iconName="action:apex" iconPosition="left" onclick="{!c.doHandleClick }" /></div>

Click on the Controller and use below code

doHandleClick : function(component, event, helper) {
helper.onHandleClick(component, event, helper);

Click on the helper and then use below code for helper

onHandleClick : function(component, event, helper) {
// Get the action of Controller (Apex) Class
var action = component.get('c.makeAPICall');

// set the callback which will return the response from apex
action.setCallback(this, function(response){
// get the state
var state = response.getState();
if( (state === 'SUCCESS' || state ==='DRAFT') && component.isValid()){
// get the response
var responseValue = response.getReturnValue();
// Parse the respose
var responseData = JSON.parse(responseValue);
} else if( state === 'INCOMPLETE'){
console.log("User is offline, device doesn't support drafts.");
} else if( state === 'ERROR'){
console.log('Problem saving record, error: ' +
} else{
console.log('Unknown problem, state: ' + state +
', error: ' + JSON.stringify(response.getError()));
// send the action to the server which will call the apex and will return the response

Step4 – In Final Step Test the Component using Lightning Application. File -> New -> Lightning Application -> Enter Name -> Submit -> Use below Code

<aura:application extends='force:slds' >

Note: – If Your component name is different then use the name of your component instead of MakiAPICall.

Output of the above code

Salesforce – Quickbooks Online Integration – oAuth 2.O

Hi All, Hope you all enjoyed my previous Integration related posts. I have come up with another integration. In this post we will make connection between Salesforce and Quickbook System using Apex, VF page.

Earlier Quickbooks uses oAuth 1.0 for the authentication but now it has updated it’s API and using oAuth 2.0 so in this Integration we are going to use oAuth 2.0

Step1 – Create a Custom Object OR Custom Metadata to store the information about Access and Refresh Token. If you are thinking about to use Custom Setting the answer is No because Access Token length is more than 255 Character and in Custom Setting we can store data upto 255 Character.

Setup -> Create -> Objects -> New -> Your Object will look like below image

QuickBooks Infos Object

Step2 – Create a Trail Account of QuickBooks From Here.

Step3 – Create a connected App into QuickBooks Developer account, Follow the steps given into this Link. Please enter a redirect URI. for example if you want to redirect into “QuickbookConnection” VF page and your org base URL is “; then your Redirect URI will be as given below


Step4 – Now, in this Step get the Consumer Secret and Consumer Key and to get the key follow the steps given in This Link.

Connected App

Step5 – Now, Create a Apex Class. File -> New -> Apex Class -> Name it “QuickbookConnection” -> OK. Use below code the class

Step5 – Create a VF page. File -> New -> Visualforce Page -> Name “QuickbookConnection” -> OK. and use below code for this page

&lt;apex:page controller="QuickbookConnection"&gt;
&lt;apex:slds /&gt;
&lt;apex:form id="theForm" &gt;
&lt;apex:pageblock &gt;
&lt;apex:pageMessages &gt;&lt;/apex:pageMessages&gt;
&lt;apex:actionstatus id="statusAuthQuickBooks"&gt;
&lt;apex:facet name="start"&gt;
&lt;div class="waitingSearchDiv" id="el_loading" style="background-color: #fbfbfb; height:100%;opacity:0.65;width:100%;"&gt;
&lt;div class="waitingHolder" style="top: 100px; width: 91px;"&gt;
&lt;img class="waitingImage" src="/img/loading.gif" title="Please Wait..." /&gt;
&lt;span class="waitingDescription"&gt;Loading...&lt;/span&gt;&lt;/div&gt;
&lt;apex:pageBlockButtons location="top"&gt;
&lt;apex:commandButton action="{!doAuthorizationQuickBooks}" value="Authorize with Quickbooks" /&gt;
&lt;apex:commandButton action="{!doFetchAccessToken}" value="Complete Authorzation" status="statusAuthQuickBooks"
reRender="theForm" /&gt;

tada we have done with the coding and configuration part, now time to test the functionality. Click preview on the VF page. Click on Authorize with QuickBooks it will take you to login page of QuickBooks login with your username and password.

If you have more than 1 Sandbox it will list all the sandbox over there select one which you want to integrate.

Authorize the Application and you will be redirected to the same page now click on Complete Authorization it will create a record for the custom Object that you have created with success message

See the working in below gif Image

Salesforce - Quickbooks Working.gif

Now, We have access token we can make the callout to get the data from QuickBooks into Salesforce. You can find the complete code form Here.

If you have any problem then please come up into comment section.

Happy Learning 🙂 😉

When Salesforce Admin should Code

When Salesforce Admin Should Code

Hi Friends, Hope you all are enjoying my posts. In this post, I will let you all especially Salesforce Admins when they should code, in other words, what are the scenarios when admin need to code.

I came up with some scenarios where admin should go for the code.

1 – Throw an Error message When trying to delete Account that has Closed Won Opportunity.

We can not show the Error message when trying to delete the account which has Closed Won Opportunity using any Salesforce  Out-of-Box functionality. So, admin should go for Apex Trigger to show the proper Error message.



Use below code for trigger to show the error

trigger AccountTrigger on Account (before delete) {
// Prevent the deletion of accounts if they have related won opportunities.
if(Trigger.isBefore && Trigger.isDelete){
for(Account acc : [Select Id, Name, (Select Id, Name From Opportunities WHere IsClosed=true) From Account
WHere Id IN : Trigger.oldMap.keySet()]){
if(acc.Opportunities.size() > 0){
trigger.oldMap.get(acc.Id).addError('Can not Delete Account, Because Account have one or more Closed Opportunity ');

4.png2 – Restoring the duplicate Data from the Recycle bin. A Salesforce admin should go for apex trigger in order to prevent the duplicate record in Salesforce Database

3 – Update Associated Contacts when a User is created or Update.

Another example where admin should code is the requirement to update the associated contact whenever a user is created or updated.


trigger UserTrigger on User (After insert, After Update) {
/* Take a set of Id to store the Contact Ids */
Set contactIdsSet = new Set();
/* prepare a Map with Contact Ids and User Name */
Map contactIdswithUserName_Map = new Map();
for(User u : Trigger.New){
if(u.ContactId != null){
contactIdswithUserName_Map.put(u.ContactId, U.Name);


/* Call handler Class method to update Contact with Respective User FirstName + LastName */


UserTriggerHandler – Use @future annonation to make the dml

public class UserTriggerHandler{

public static void updateContacts(Map contactIdswithUserName_Map){
List contactList = new List();
contactList = [Select Id, Name, UserName__c From Contact Where Id IN : contactIdswithUserName_Map.keySet()];
for(Contact c : contactList){
c.UserName__c = contactIdswithUserName_Map.get(c.Id);

update contactList;

4 – Writing the Rollups for the lookup Relationship

Rollup the child record data into parent record.

See the post here

5 – Automatic Lead Conversion

Convert Lead automatically when lead reaches the certain stage. like Qualified, or any other stage that you want.

To do this you can go for process builder which will call an apex class method and do the conversion


Create a trigger on Lead object and then call the handler class method

trigger code

trigger LeadTrigger on Lead (After Insert, After Update) {
List leadIdsSet = new List();
for(Lead l : Trigger.New){
if(l.status == 'Qualified')


Handler Class Code

Public class LeadTriggerHandler
public static void convertLeads(List LeadIds)
/* fetch the converted Status */
LeadStatus CLeadStatus= [SELECT Id, MasterLabel FROM LeadStatus WHERE IsConverted=true Limit 1];
List LeadconvertList = new List();
for(id currentlead: LeadIds){
Database.LeadConvert Leadconvert = new Database.LeadConvert();
Leadconvert.setDoNotCreateOpportunity(TRUE); //Remove this line if you want to create an opportunity from Lead Conversion

if (!LeadconvertList.isEmpty()) {
List lcr = Database.convertLead(LeadconvertList);

Whenever I will found more scenarios then I will update this post!

Any questions comment below enjoy learning enjoy salesforce.

Difference between Render, reRender and renderAs

Most of the Salesforce Developers are confused when to use render, reRender, and reRender. So, here is explanation

Render: – Is used to show/hide the particular block, output panel or input/output fields based on the condition.

Example: – You have 2 fields one is visible and second is hidden, you want the second field to be visible when the first field is filled then use render.

<apex:pageBlockTable value=”{!empList}” var=”emp” rendered=”{!empList.size > 0}”>
                  <apex:column value=”{!emp.Name}”/>

reRerender: – Is used to refresh the particular output panel, block, and or fields after a server request has been completed. It uses Id to reRender.

Example: – You have a VF page where you want to add Contacts related to Account and also wanted to show the recently added Contacts then use reRender to refresh the block which is showing the contact list.

renderAs: – Is used to open the Visualforce Page in different format like- HTML, pdf, and excel

Example: – To show the invoice in PDF format.

for pdf – renderAs =”pdf”

for HTML – renderAs =”html”

for excel – <apex:page controller=”contactquery” contentType=”application/” cache=”true”>

For more info Visit Export data in Excel or PDF format using Visualforce

Difference between Action function, Action Support, and Action Poller

Action Function: –

Action Function is used in the Visualforce page to call the Service Side method using JavaScript and does not add the Ajax Request before calling the Controller method.

<apex:actionFunction name=”myactionfun” action=”{!actionFunctionTest}” reRender=”pgBlock, pbSection” />

Let us talk about above example. In any Javascript Method where the name of ActionFunction ( In our example myactionfun() ) will be invoked, it will call the controller method name actionFunctionTest. Example myactionfun();

Action Support: –

As the name indicates action support is used to provide the support to the input field where we can not get event either manually or external event. It adds the AJAX request to VF page and then Calls the Controller method. For

For example, if we want to call any server side method when input changes then we will go for action support because we can not get any event for this.

<apex:inputText value=”{!dummyString}” >
                      <apex:actionSupport event=”onchange” action=”{!actionSupportTest}”                                     reRender=”pgBlock, pbSection” />

Action Poller: –

A timer that sends an AJAX request to the server according to a time interval that you specify. Each request can result in a full or partial page update.

<apex:actionPoller action=”{!incrementCounter}” reRender=”counter” interval=”15″ enabled = “true” />

Enabled attribute is used to make poller as active or inactive by default value is true. If we provide false then poller will be inactivate.
