Level II Fields

PayFields provides Level II fields for merchants who use additional information to qualify for reduced interchange fees. The example below shows how to add the Level II/III fields and set their values:

PayFields.config.order = {order number};
PayFields.config.tax = {tax number};
PayFields.config.dicount = {discount number};
PayFields.config.shipping = {shipping number};
PayFields.config.duty = {duty number}
PayFields.config.items = {items Object}
PayFields.config.billingAddress = {
  address: '123 Madison Street',
  city: 'New York',
  state: 'NY',
  zip: '12345',
  email: '',
  phone: '',
  address2: 'suite 555',
  company: 'Essential Co',
  country: 'USA'
};
PayFields.config.additionalData = {Additional Object};
PayFields.config.invoiceResult = {Invoice Object}

Billing Address

Billing Address information can be entered by the customer or submitted by the merchant, if the merchant already knows the values. There are two ways to set the billing address:

PayFields.config.billingAddress = {} - This is the preferred method for setting billing address fields. The billingAddress object makes it easier to customize the way the address fields are displayed on your page and works with common JavaScript frameworks. With the billingAddress object, your customer can also edit prefilled form values.
PayFields.fields = [] - The fields array displays all of the billing address fields inline on your page and requires absolute positioning in your CSS. Customers cannot edit prefilled values.

Both methods allow you to toggle the visibility of certain fields, define optional fields, and prefill form values using defaults or information previously entered by your customer.

Payfields.config.billingAddress

Add fields to the PayFields.config.billingAddress object as shown in the sample code below to include them on your payment forms:

PayFields.config.billingAddress = {
  address: this.address1,
  city: this.city,
  state: this.state1,
  zip: this.zip,
  phone: this.phone,
  email: this.email
}

Payfields.fields

The sections below describe how to use the fields array for the following cases: customer entry, prefill and display, prefill and do not display.

Customer Entry

To add billing address fields to a payment page so that a customer can fill in the information use the PayFields.fields = []; function to define the elements that will display the billing address fields.

For customer entry of the billing address, do not set values for the individual address fields. If you set values for the fields in the "address" object, the customer will NOT be able to modify the values.

The code below shows how to include the "address" type in the PayFields.fields function:

PayFields.fields = [
  {type: "number", element: "#number"},
  {type: "cvv", element: "#cvv"},
  {type: "name", element: "#name"},
  {type: "expiration", element: "#expiration"},
  {type: "address", element: "#address"}
]

Prefill and Display

To prefill the billing address and display the values use the PayFields.fields function to define the elements that will display the billing address fields and the values that they will contain.

The code below shows how to prefill and display the billing address fields:

Prefill and Do Not Display

Use the PayFields.config.billingAddress function to set values for all of the billing address elements. These values will be sent directly to Payrix when the transaction is submitted, and they will not be displayed to the customer.

The code below shows how to set previously know billing address values using the PayFields.config.billingAddress function:

Optional Fields

Use the sample code below to define optional fields for your billing address form when using the PayFields.fields array:

The values in the optionalFields array should be the selector for the field. The following values are available as optional fields:

#phone
#email
#expiration
#payment_cvv
#address1
#city
#state
#zip
#customer_id
#routing
#account_type
#account_number

Customization

PayFields provides the following features that can be used to customize your user experience:

Placeholder Text - Add placeholder text to the form fields to provide examples or explanations of the required data.
CSS - Use CSS to define the look and feel of the payment fields.

Placeholder Text

To change the placeholder for any of the fields, create a PayFields.customizations.style = {}; object and set the key to the field and the value to the desired placeholder text. The example below shows how to set the placeholder text:

Use the following keys to the set placeholder text for the associated field: '#payment_number', '#expiration', '#payment_cvv', '#name', '#address1', '#city', '#state', '#zip', '#email', and '#phone'.

CSS

Payrix passes a style object with the class(es) or ids to be styled. Specific classes such as .number have priority over more generic classes such as .input. In other words, classes will stack on each other.

The code below shows an example of setting styles for the .input class:

The table below defines the classes and IDs available for styling PayFields elements:

Code Snippet	Field Description	Type

Card Swipe Popup

The card swipe popup opens a separate modal that supports collecting payment information from an unencrypted card reader. The image below shows the card swipe popup:

PayFields supports two ways to launch the card swipe popup: the PayFields.swipePopup(); function and the card swipe popup button.

The sections below provide examples of each:

Card Swipe Popup Function

Add the code below in a <script> tag to enable the card swipe popup:

Call the PayFields.swipePopup(); function to display the popup:

A standard implementation calls the swipePopup() function using an event listener attached to a button, as shown in the code below:

Card Swipe Button

The card swipe button opens the card swipe modal when clicked. The code below shows how to add the card swipe button:

Assign the value set in the element field to a <div> on the payment page. Payfields will display a button in the <div> with the text assigned with the value field as the label.

Submit Transaction Button

The example below shows how to add a preconfigured button to submit transaction information to Payrix for processing:

The text set for the value element will appear as the label on the button.

Zero Dollar Auth

Use zero dollar auth transactions to obtain approval for a payment method without actually charging the cardholder’s account. Zero dollar auth transactions are a component of setting up automatic and recurring payments. Follow the steps below to perform zero dollar auth transaction:

Set the PayFields transaction mode to 'txn' as shown below:
Set the transaction amount to `0` as shown below. Use a string for the amount:
Set the transaction type to 'auth':

Tokenization

The PayFields tokenization feature makes it possible to store a reference to payment information that can be used to process automatic or recurring payments. PayFields supports token only and transaction+token functions.

The sections below provide examples of how to generate tokens using PayFields.

Token Only

To tokenize a card payment, set the Payfields.config.mode value to 'token', as shown below, to submit a token-only request (specific to card payments only, see eCheck instructions below.)

To tokenize an eCheck payment, set the Payfields.config.mode value to 'txnToken' must be used:

Token with Transaction

Set a transaction amount and set the PayFields.config.mode value to 'txnToken', as shown below, to submit a payment transaction and generate a token at the same time:

Transaction with Token Hash Only

Invoicing

Use the PayFields.config.invoiceResult object to apply a full or partial payment to an invoice:

The object must include a value for the invoice ID and associated shipping data. If the amount of the payment being submitted is less than the total amount of the invoice, a partial payment will be applied. If the invoice has already been fully paid, PayFields will return an error.

You can only associated a payment with one invoice. You cannot use the invoiceResult object to apply a single payment to multiple invoices.

The values for shippingState and shippingCountry are always abbreviations.

Customer Account Creation

Create a stored customer record when you create a payment token using the PayFields.config.customer object, as shown in the example below:

If customerID is not passed with the transaction, in either mode, a new customer account will be created.

DOM Styling

Certain fields can be hidden by setting display: "none" in the PayFields.customizations.style object when you are prepopulating fields using the PayFields.array. The sample code below shows all of the fields that can be hidden:
