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

html
<form action="https://primeiropay.docs.oppwa.com/tutorials/integration-guide/advanced-options" class="paymentWidgets" data-brands="VISA MASTER AMEX"></form>
css
body {background-color:#f6f6f5;}
js
var wpwlOptions = {
  style:"card", 
  onReady: function(e){
    $('.wpwl-form-card').find('.wpwl-button-pay').on('click', function(e){
      validateHolder(e);
    });
  },
  onBeforeSubmitCard: function(e){
    return validateHolder(e);
  }
}
function validateHolder(e){
  var holder = $('.wpwl-control-cardHolder').val();
  if (holder.trim().length < 2){
    $('.wpwl-control-cardHolder').addClass('wpwl-has-error').after('<div class="wpwl-hint wpwl-hint-cardHolderError">Invalid card holder</div>');
    return false;
  }
  return true;
}

Add custom fields

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

              '<div class="wpwl-wrapper wpwl-wrapper-custom" style="display:inline-block">' +
              '<select name="recurring.numberOfInstallments"><option value="1">1</option><option value="3">3</option><option value="5">5</option></select>' +
              '</div>';
