8,008

In today’s highly competitive business landscape, every organization wants to implement business process mapping onto a CRM such as Salesforce to boost team productivity and efficiency.

Businesses of all sizes can reap the benefits by integrating Salesforce with existing systems – both with on-premise and cloud solutions that can dramatically increase team productivity, encourage employee collaboration, and help convert turn leads into clients.

Salesforce, a top-rated customer relationship management tool, can be easily integrated with many third-party tools to empower sales, close more deals, and enhance the overall customer experience. In this blog, we’ll provide a brief introduction to Salesforce and Google Contacts integration.

Before delving deeper into the process of integrating Salesforce with Google Contacts, let’s have a quick introduction to Google Contacts.

What is Google Contacts?

Google Contacts is a powerful tool that you can use to organize, view, and manage your contacts. Google Contacts allows you to manage all your contacts in one place by creating contact groups separated between customers, vendors, prospects, and others. Google Contacts’s capabilities also include creating a personal mailing list and quickly sending messages or invitations from the calendar to a group of people you contact frequently.

Process To Integrate Salesforce With Google Contacts

Below is the process we followed for Salesforce And Google Contacts Integration:

Firstly, we need to create a new project for Google Contacts on the Google Developer Console.
Create a VisualForce page and Apex class to get access token and will fetch all contact details.

Create Apex Class and Visualforce Page

Create two apex classes googleAuthContactClass and getContactList.
Create a visualforce page named googleAuthContactPage.

Enabling Google Contacts API Setting On Google Developer Console

Step 1: Click on Enable APIs and Services and go to the Contact API.

Step 2: Create a new project for Contact API

After the above step, click on the create button to create the project.

Configure the OAuth consent screen with User Type external and follow the below steps.

Step 3: Now, we need to create credentials for client ID and client secret.

Step 4: Copy the Client ID and Client Secret for further process.

Note: You need to write the following URL in the picture for Authorized Redirect URL and Consent Screen URL.

After clicking on the preview button on the VF page, we will get this URL.

Now we have to create an apex class and visualforce page.

Open Developer console and create 2 apex class named googleAuthContactClass and getContactList
Create a VisualForce page named googleAuthContactPage

Apex class:

1. googleAuthContactClass

public class googleAuthContactClass{

private String code;

public string authtoken{get;set;}

public string bodyprint{get;set;}

public string phoneNumber{get;set;}

public List<googleContactInfo> googleContactInfotList {get; set;}
