Purpose of Integration

The main purpose of this blog is to integrate the Paypal Payment Gateway with Salesforce. Paypal is useful to make the payment from e-com community or sites.In this blog, we are going to implement Paypal integration with Salesforce for a basic payment for Merchant Type account, the payments would be from Customers using Credit Cards like Visa etc. where customer enters the payment details on lightning component which will complete the payment on click of submit button.Firstly,we need to set up a paypal account.So let’s get started.

Integration Steps:

1) Set up Paypal Account:

1.Create a Personal or Business Paypal Account.

(i).To create business Paypal Account visit developer.paypal.com

(ii).To create Personal/Individual Account visit https://www.paypal.com/in/signup/account

For this blog,I have created a Business Paypal Account.

2.Login with your credentials and you will be landed in Dashboard Page.

3.Select Sandbox under Accounts from left side.You will find one default Business and one Personal account.

Click on Create Account and Create one Business account and Personal Account.You can also create custom Account.

Select the Business Account you created now and click View/Edit Account and click Upgrade to Pro beside Account Type Business.Because Business Pro Account is required for Business(Merchant)  Account to process transactions.

4.Copy the API Credentials(username,password and signature) generated for  the Business Pro Account.This credentials will be used in the Salesforce Apex Class.

2) Set up Salesforce:

(i).Create a lightning component with a button Paypal Integration, onclick of a button a modal with a payment detail form opens up where the customer needs to fill the payment details. On Submitting the details the amount will be debited from the payee account and will be credited in the paypal account.
