PayPal
PayPal is a payment service that facilitates payments between parties through online funds transfers. PayPal allows customers to establish an account on its website, which is connected to a user's credit card or checking account.

Step 3: Authorize a PayPal source
When you create a PayPal source, the customer is required to authorize the charge at PayPal. You can accomplish this by either redirecting the customer to PayPal or using the PayPal SDK to authorize the charge as part of your experience.
Redirecting the customer to PayPal for authorization
To redirect your customer to PayPal for authorization, use the redirectUrl parameter in your createSource response.
window.location.href = sourceResponse.redirect.redirectUrl;
At PayPal, the customer can authorize or cancel the transaction when presented with the transaction details. If the authorization is successful, the customer will be redirected to the PayPal Return URL parameter you specified when you created the source. If the customer cancels, they will be returned to the PayPal Cancel URL parameter you specified.
Using the PayPal SDK to authorize payment
Use the PayPal Checkout SDK to streamline the authorizing PayPal transactions. This will allow you to control things like the appearance of the PayPal button and embed the entire experience into your workflow.
The PayPal SDK guide is located here: https://developer.paypal.com/docs/archive/checkout/​
More details on how you can customize the PayPal button is located here: https://developer.paypal.com/docs/archive/checkout/how-to/customize-button/#​
Example:
Include the PayPal Checkout SDK on your page and specify a location where the button will appear.
 Use the PayPal SDK to customize and place the PayPal button on your page. The PayPal SDK returns two functions, onAuthorize and onCancel. If the payment was authorized, use the source you created earlier by attaching to an order or cart.

PayPal login
Step 4: Use the authorized source
Once authorized, you can use the source by attaching it to a cart or attaching it to a shopper.
Option 1. Attach the source to a cart
POST /v1/shoppers/me/carts/active/apply-payment-method
POST /v1/shoppers/me/carts/active/apply-payment-method
{
  "paymentMethod": {
    "sourceId": "e7ba0595-059c-460c-bad8-2812123b9313"
  }
}
Option 2. Attach the source to a shopper
POST /v1/shoppers/me/payment-options
POST /v1/shoppers/me/payment-options
{
  "paymentOption": {
    "nickName": "My Token",
    "isDefault": "true",
    "sourceId": "61033d62-c0f4-4a7e-b844-07daf26ba84e"
  }
}
PayPal Credit
Additional Setup Required: If you are interested in using PayPal Credit, contact your Account Manager. The Account Manager will send set up instructions for PayPal Credit banners after you sign the client addendum.
PayPal Credit allows consumers to buy online and pay later for their products. This payment method is accepted in thousands of online stores and is available everywhere PayPal is accepted (as long as the PayPal Credit and PayPal accounts are linked). PayPal Credit uses the date of birth and last 4 digits of SSN to approve or deny a consumer for a line of credit, and the applicant will be notified within seconds whether they have been approved or not.
Create a PayPal payment method for your app or website in four easy steps:
​Step 1: Build a PayPal Credit source request object​
​Step 2: Create a PayPal Credit source using DigitalRiver.js​
​Step 3: Authorize a PayPal Credit source​
​Step 4: Use the authorized source​
Step 1: Build a Credit source request object
Build a Credit Source Request object. A PayPal Billing Credit Source Request object requires the following fields.
Field
Value
type
payPalCredit
amount
The total value of the transaction.
currency
The currency of the transaction.
payPalCredit
 A PayPal Source Details object that includes the details of the transaction.
Step 2: Create a PayPal Credit source using DigitalRiver.js
Use the DigitalRiver.js library to create and mount elements to the HTML container.

    "type": "payPalCredit",
    "sessionId": "ea03bf6f-84ef-4993-b1e7-b7d5ecf71d1f",
    "payPal": {
        "returnUrl": "http://mypage.com",
        "cancelUrl": "https://mypage.com/cancel"
    }
}
  
digitalriver.createSource(data).then(function(result) {
    if (result.error) {
        //handle errors
    } else {
        var source = result.source;
        //send source to back end
        sendToBackend(source);
    }
});

            }
        },
        "token": "EC-1HD67063RG318840B"
    }
}
Step 3: Authorize a PayPal Credit source
When you create a PayPal Credit Source, the customer is required to authorize the charge at PayPal. You can accomplish this by either redirecting the customer to PayPal or use the PayPal SDK to authorize the charge as part of your experience.
Redirecting the customer to PayPal for authorization
To redirect your customer to PayPal for authorization, use the redirectUrl parameter in your createSource response.
Redirect example
Redirect example
window.location.href = sourceResponse.redirect.redirectUrl;
PayPal will present the customer with the transaction details where they can authorize or cancel the transaction. A successful authorization redirects the customer to the PayPal Return URL parameter you specified when you created the source. If the customer cancels, they will return to the PayPal Cancel URL parameter you specified when you created the source.
Using the PayPal SDK to authorize payment
Use the PayPal Checkout SDK to streamline the authorizing PayPal transactions. This will allow you to control things like the appearance of the PayPal button and embed the entire experience into your workflow.
The PayPal SDK guide is located here: https://developer.paypal.com/docs/archive/checkout/​
For more details on how you can customize the PayPal button, go to https://developer.paypal.com/docs/archive/checkout/how-to/customize-button/#​
Example:
Include the PayPal Checkout SDK on your page and specify a location where the button will appear.

<script src="https://www.paypalobjects.com/api/checkout.js"></script>
<div id="paypal-button"></div>
 Use the PayPal SDK to customize and place the PayPal button on your page. The PayPal SDK returns two functions, onAuthorize and onCancel. If the payment was authorized, use the source you created earlier by attaching to an order or cart.

                //handle the errors that were returned
                handleErrors(result.error)
            } else {
                return result.source.payPalCredit.token;
            }
        });
    },
    // Execute the payment
    onAuthorize: function(data, actions) {
        //the payment has been authorized, use the source and attach it to your customer's account.
        doSomething();
    },
    onCancel: function(data) {
        //the payment has been cancelled, do something to try and get the shopper back on track
        doSomethingElse();
    }
}, '#paypal-button');
Step 4: Use the Authorized source
Once authorized, you can use the source by attaching it to a cart.
Attach the source to a cart
POST /v1/shoppers/me/carts/active/apply-payment-method
POST /v1/shoppers/me/carts/active/apply-payment-method
{
  "paymentMethod": {
    "sourceId": "e7ba0595-059c-460c-bad8-2812123b9313"
  }
}
Pay in 4
Additional setup optional: If you are interested in promoting Pay in 4, contact your Customer Success Representative. The Representative will provide the set-up instructions for PayPal in 4 banners.
Pay in 4 is a short-term card installment payment option automatically provided by PayPal when a customer signs in to PayPal Checkout. Pay in 4 allows United States shoppers to pay for physical good purchases ranging from $30 - $600 in four interest-free payments every two weeks over six weeks, with the first payment due at checkout. This option is currently only available in the United States.
When a customer selects this payment method, a "soft hit" will appear in their credit report.
