    }
}
  
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 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:

1. Include the PayPal Checkout SDK on your page and specify a location where the button will appear.

2. 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.

        return digitalriver.createSource(paypalSourceData).then(function(result) {
            if (result.error) {
                //handle the errors that were returned
                handleErrors(result.error)
            } else {
                return result.source.payPal.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 to an order or cart.

Attach the source to a cart

  "paymentMethod": {
    "sourceId": "e7ba0595-059c-460c-bad8-2812123b9313"
  }

Step 3. Authorize a PayPal Billing Agreement source

When you create a PayPal Billing Agreement source, the customer is required to authorize the charge through 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.

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.

            } else {
                return result.source.payPal.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 or attaching it to a shopper.

Option 1. Attach the source to a cart

{
  "paymentMethod": {
    "sourceId": "e7ba0595-059c-460c-bad8-2812123b9313"
  }
}

Option 2. Attach the source to a shopper

{
  "paymentOption": {
    "nickName": "My Token",
    "isDefault": "true",
    "sourceId": "61033d62-c0f4-4a7e-b844-07daf26ba84e"
  }

PayPal Credit

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:

1. ​Build a PayPal Credit source request object​

2. ​Create a PayPal Credit source using DigitalRiver.js​

3. ​Authorize a PayPal Credit source​

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.

Step 2. Create a PayPal Credit source using DigitalRiver.js

To create a PayPal Credit payment source, you must use the createSource method exposed via DigitalRiver.js.

var data = {
    "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.

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:

1. 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>

2. 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.
