Advanced Options

Here you can find some examples of advanced workflow customization for PayUnity.Flex. Each of the examples provided use the wpwlOptions variable, the full reference for which can be found on our PayUnity.Flex API Reference.

Please note that JavaScript examples from PayUnity.Flex can be used only when including jQuery.

<script src="https://code.jquery.com/jquery.js" type="text/javascript"></script>

Add custom fields

You can add additional parameters to the payment form using the wpwlOptions variable, prior to loading PayUnity.Flex. In the example above, we add a custom parameter to the payment form for recording the number of installments requested by the customer. The steps are listed below.

  1. Prepare the checkout
  2. Using the wpwlOptions API onLoad event, add the custom field HTML to the payment form
  3. Set the name of the html input field to your API parameter e.g. recurring.numberOfInstallments

Change label

You can change a label in the payment form using the wpwlOptions variable, prior to loading the PayUnity.Flex payment widget. In the following example, we'll change the credit card brand label in the payment form.

  1. Prepare the order
  2. Using the wpwlOptions API onLoad event, use a JQuery selector to set the desired value of the label

Have card holder mandatory

By default the card holder is optional. Some integrations would like to have it mandatory. In order to achieve this we can implement the check on the onBeforeSubmitCard event, like below:

  1. Prepare the checkout
  2. Using the wpwlOptions API onBeforeCardSubmit event, check if the holder contains 2 or more characters.

Create custom UI

You can change the behavior of the payment page when there are multiple types of payment methods using the wpwlOptions variable, prior to loading the PayUnity.Flex payment widget.

  1. Prepare the checkout
  2. Using the wpwlOptions API onLoad event, iterate through each .wpwl-container adding custom HTML before the container
  3. Create a JQuery click handler to show the container on click.

Create custom UI - Box model

You can change the behavior of the payment page when there are multiple types of payment methods using the wpwlOptions variable, prior to loading the PayUnity.Flex payment widget.

  1. Prepare the checkout
  2. Using the wpwlOptions API onReady event and make some adaptions to the containers.
  3. Create a JQuery click handler to show the container on click.

Summary page

It is possible to use PayUnity.Flex to temporarily store the payment information after submission, rather than executing it straight away. This can be useful if you want to display an order summary page before committing the payment. This can be done using the wpwlOptions variable, prior to loading the PayUnity.Flex.

To commit the payment after the summary page has been displayed, you can include the following form on the summary page. When the submit button is pressed, the payment will be executed.

<form action="https://test.oppwa.com/v1/checkouts/{id}/payment" method="POST"> 

<input type="submit" value="Pay now" /> 

Store payment details

There are two ways to store the payment details used during a checkout:

  1. Set the createRegistration parameter to true during step 1 - prepare the checkout
  2. Add a checkbox to the PayUnity.Flex form to let the customer decide whether or not to store the card details.

(Option 2 is demonstrated in the example below).


Field order in the payment form

PayUnity.Flex allows you to modify the order of the fields in the payment form. As a result of this reordering, the order in which fields get tabbed will be adjusted accordingly. For details, please take a look at the JavaScript section in the following integration form.


Billing Address

It's possible to have the billing address fields available and even have them pre-filled. There are two options to do this:

1. Pre-filled data in the billing address that can be editable

To display the form, use the following option in wpwlOptions:

    var wpwlOptions = {
        billingAddress: {
            country: "US",
            state: "NY",
            city: "New York",
            postcode: "12345",
            street1: "Suite 1234",
            street2: "Some Road"
        },
        mandatoryBillingFields:{
            country: true,
            state: true,
            city: true,
            postcode: true,
            street1: true,
            street2: false
        }
    }

2. Display empty fields in the billing address so the shopper can edit it

To display the form, use the following option in wpwlOptions:

    var wpwlOptions = {
        billingAddress: {},
        mandatoryBillingFields:{
            country: true,
            state: true,
            city: true,
            postcode: true,
            street1: true,
            street2: false
        }
    }
Remarks:
  • Use the mandatoryBillingFields options in order to control if some field will be validated (for empty value) or not.
  • The state will be a dropdown for US and Canada.

MaskCvv page

It is possible to mask cvv on PayUnity.Flex, which can be done by setting "maskCvv" to true in wpwlOptions variable, prior to loading the PayUnity.Flex payment widget.

    var wpwlOptions = {
        maskCvv: true
    }

Brand detection

To influence the brand detection behavior, use the following options in wpwlOptions variable prior to loading the PayUnity.Flex payment widget.

    var wpwlOptions = {
        // Enable brand detection
        brandDetection: true,
        
        // Use our internal BIN list to precisely detect brands
        brandDetectionType: "binlist",
        
        // Give priority to detected brands
        brandDetectionPriority: ["CARTEBANCAIRE","VISA","MAESTRO","MASTER"]
    }

Hide detected brands

Sometimes you might want to hide some brands when multiple brands are detected. This can guide the shopper to select your preferred brand. There are several options to implement this feature:

  1. If you use your own brand images, implement onDetectBrand. This method is called with a list of detected brands. With this information you can choose to show or hide your images.
  2. Use PayUnity.Flex images the "logos" style. By default this style dynamically displays all detected brands as you type the card number. You can implement onChangeBrand to change this behavior.
The following snippet gives an example how to implement Option 2. Except for the first detected brand, all other brands are hidden behind three dots (...). The hidden brands are shown only after the three dots are clicked.

Try for example the BIN 513678 from which multiple brands are detected.
