## Customize customer credit and related scripts

Read this section to understand changes made to the `CustomerCredit` cartridge and its script code to support the feature. Use these changes to create a successful integration based on your Customer Credit method choice.

{% hint style="info" %}
**Note:** Do not forget to compile client-side scripts after making your changes in the source code.
{% endhint %}

### Customize the Checkout script

You can customize the cartridge Checkout script (`int_digitalriver_customercredit/cartridge/client/default/js/checkout/checkout.js`) to update the customer credit amount in the payment section. Refer to the Checkout script section of [Extend the Salesforce B2C LINK Cartridge](https://docs.digitalriver.com/salesforce-b2c-link-cartridge/salesforce-b2c-link-cartridge-3.2/extending-the-salesforce-b2c-link-cartridge) for an example.

### Customize the Billing Script

This customization example outlines changes you can make to the cartridge Billing script (`int_digitalriver_customercredit/cartridge/client/default/js/checkout/billing.js`).  Use these changes to update the customer credit amount in the payment section. These changes are the following:

Change the `updatePaymentInformation` function so that it updates the customer credit information in the payment section on the Checkout page.

```
output.methods.updatePaymentInformation = function (order) {
    // update payment details
    var $paymentSummary = $('.payment-details');
    var htmlToAppend = '';
    var htmlGiftToAppend = '';

    if (order.billing.payment && order.billing.payment.selectedPaymentInstruments
        && order.billing.payment.selectedPaymentInstruments.length > 0) {
        var paymentInstruments = order.billing.payment.selectedPaymentInstruments;
        var index = 1;
        /*
            @IG:
            Modify labelCustomerCredit value with the value you want to be displayed on the UI
        */
        var labelCustomerCredit = $('#dr-list-of-applied-customercredits').data('payment-info-text');
        for (var i = 0; i < paymentInstruments.length; i++) {
            /*
                @IG:
                Modify the following condition depending on your implementation of secondary payment
            */
            if (paymentInstruments[i].paymentMethod === 'GIFT_CERTIFICATE' && paymentInstruments[i].giftCertificateCode === 'customer_credit_code') {
                htmlGiftToAppend += '<div class="col-6 start-lines">'
                    + '<span class="order-receipt-label">' + labelCustomerCredit + ' ' + index + '</span>'
                    + '</div><div class="col-6 end-lines">'
                    + '<div class="text-right">'
                    + '<span>' + paymentInstruments[i].formattedAmount + '</span></div></div>';
                index++;
            } else if (paymentInstruments[i].paymentType === 'creditCard') {
                htmlToAppend += '<div class="row leading-lines">'
                    + '<div class="col-6 start-lines">'
                    + '<span>' + order.resources.cardType + ' ' + paymentInstruments[i].type + '</span></div>'
                    + '<div class="col-6 end-lines"><div class="text-right">'
                    + '<span>' + paymentInstruments[i].formattedAmount + '</span></div></div></div>'
                    + '<div>' + paymentInstruments[i].maskedCreditCardNumber + '</div>'
                    + '<div><span>'
                    + order.resources.cardEnding + ' '
                    + paymentInstruments[i].expirationMonth
                    + '/' + paymentInstruments[i].expirationYear
                    + '</span></div>';
            } else if (order.billing.payment.selectedPaymentInstruments[0].paymentMethod !== 'DIGITAL_RIVER_ZERO_PAYMENT') {
                htmlToAppend += '<div class="row leading-lines">'
                + '<div class="col-6 start-lines">'
                + '<span>' + paymentInstruments[i].paymentType + '</span></div>'
                + '<div class="col-6 end-lines"><div class="text-right">'
                + '<span>' + paymentInstruments[i].formattedAmount + '</span></div></div></div>';
            }
        }
        if (htmlGiftToAppend) {
            htmlGiftToAppend = '<div class="row leading-lines">' + htmlGiftToAppend + '</div>';
        }
    }

    $paymentSummary.empty().append(htmlGiftToAppend + htmlToAppend);

```

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/qkyCAuWWzt2VIlIOtDX3/image.png)

Modify the `labelCustomerCredit` value to align with the value you want to be displayed in the user interface.

```
var labelCustomerCredit = $('#dr-list-of-applied-customercredits').data('payment-info-text');
```

Modify the code as follows depending on the payment method being used for Customer Credit.

```
if (paymentInstruments[i].paymentMethod === 'GIFT_CERTIFICATE' && paymentInstruments[i].giftCertificateCode === 'customer_credit_code') {
```

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/tNd8K39oCa6zw7yyzhZa/image.png)

### Customize the Summary script

In this example, you make changes to the Summary script (`int_digitalriver_customercredit/cartridge/client/default/js/checkout/summary.js` ). Use these changes to update the customer credit lines in order of Totals, Details, and Summary. The changes are the following:

Add a row and change the `updateTotals` function so that it updates the customer credit lines in order of Totals, Details, and Summary.&#x20;

```
var drHelper = require('./drHelper.js');
```

Add a totals row to the end of the function `updateTotals`.&#x20;

```
drHelper.updateCustomerCreditTotal(totals.adjustedGrandTotal);
```

## Customize server scripts

This section describes changes you can make to customize server script code to work well with your integration. You can customize things such as payment method, multiple payment instruments, payment processors, etc. These changes are the following.

#### Payment server script

Change the Payment server script (`cartridge/models/payment.js`) to implement the customer credit feature.  Modify the code at line 23 depending on the payment method, used for Customer Credit.

```
} else if (paymentInstrument.paymentMethod === 'GIFT_CERTIFICATE' && paymentInstrument.giftCertificateCode === 'customer_credit_code') {
```

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/xmpVOTmQKO63M15CF8dn/image.png)

#### CheckoutHelper server script

You can also make changes to the `checkoutHelper` server script (`cartridge/scripts/checkout/checkoutHelpers.js`) to implement the customer credit feature. Modify the `calculatePaymentTransaction` function at line 13 depending on your method of supporting multiple payment instruments.

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/jVdKqHdag9DFwEg1B318/image.png)

#### Basic\_customer\_credit script

This script was added for testing purposes only and SHOULD NOT be used as is. Either delete it or modify it based on the payment method used for Customer Credit.

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/IgynzpXTxXxcScVTIcQC/image.png)

#### drTaxHelper script

Make changes to the `drTaxHelper` server script (`cartridge/scripts/digitalRiver/drTaxHelper.js`) when implementing the customer credit feature.&#x20;

Modify the `getNonGiftCertificatePriceTotal`function  based on the payment method used for Customer Credit.

```
var paymentInstruments = basket.getGiftCertificatePaymentInstruments();
```

```
return (paymentInstrument.giftCertificateCode === 'customer_credit_code')
```

![](https://content.gitbook.com/content/jY6BnA1tuQKV0OrM7SKw/blobs/4WFifcDq82xHUJLYvnkZ/image.png)

Modify the `resetBasketCheckoutData` function depending on the payment method used for Customer Credit.

```
var paymentInstruments = basket.getGiftCertificatePaymentInstruments();
```

```
if (paymentInstrument.giftCertificateCode === 'customer_credit_code') {
```
