FAQ

What is Windcave PxPay?

Windcave PxPay 2.0 is a hosted Credit Card payment gateway, accepting payments around the world including New Zealand, Australia, North America, United Kingdom, Ireland, and Singapore.

Windcave, Payment Express, DPS?

In 2019, Payment Express (DPS) became Windcave. Read the Windcave rebranding announcement for more information.

Will this plugin work without installing Gravity Forms?

No. This plugin adds a Windcave PxPay payment gateway to Gravity Forms so that you can add online payments to your forms. You must purchase and install a copy of the Gravity Forms plugin too.

What Gravity Forms licence do I need?

Any Gravity Forms licence will do. You can use this plugin with the Basic, Pro, or Elite licences.

How do I build a form with credit card payments?

  • add one or more Product fields or a Total field to your form. The plugin will automatically detect the values assigned to these pricing fields
  • add customer name and contact information fields to your form. These fields can be mapped when creating a Windcave feed
  • add a Windcave feed, mapping your form fields to Windcave transaction fields

What is the difference between Normal and Testing (Sandbox) mode?

GF Windcave Free enables you to store two pairs of User ID and User Key credentials. When you first signup for a PxPay account with Windcave you will likely be issued development or testing credentials. Later, when you want to go live with your site, you will need to request a new User ID and User Key from Windcave. Sandbox mode enables you to switch between your live and test credentials. If you only have testing credentials, both your User ID and Test ID and User Key and Test Key should be identical. In this instance, Sandbox mode can be switched either On or Off.

Sandbox mode enables you to run tests without using real credit cards or bank accounts. You must use special test credit card details when using the test environment.

Where can I find dummy Credit Card details for testing purposes?

The Windcave eCommerce test details page has card numbers that can be used when testing.

Where will the customer be directed after they complete their Windcave Credit Card transaction?

Standard Gravity Forms submission logic applies. The customer will either be shown your chosen confirmation message, directed to a nominated page on your website, or sent to a custom URL.

Where do I find the Windcave transaction number?

Successful transaction details including the Windcave transaction number and bank authcode are shown in the Info box when you view the details of a form entry in the WordPress admin.

How do I add a confirmed payment amount and transaction number to my Gravity Forms admin or customer email?

Browse to your Gravity Form, select Notifications and use the Insert Merge Tag dropdown (Payment Amount, Transaction Number, Surcharge, and Auth Code will appear under Custom at the very bottom of the dropdown list).

NB: these custom merge tags will only work for notifications triggered by Payment Completed and Payment Failed events.

How do I change my currency type?

Use your Gravity Forms Settings page to select the currency type to pass to Windcave. Please ensure your currency type is supported by Windcave.

Capture or Authorize?

Windcave PxPay supports two transaction types – Purchase and Auth. The GF Windcave Free plugin calls them Capture and Authorize, terminology used in most other payment integrations.

Capture processes the payment immediately. Authorize holds the amount on the customer’s card for processing later.

Authorize transactions can be completed manually in Payline. Perform a transaction search, and look for its Complete button.

Can I do recurring payments?

Not yet.

Can I use Account2Account?

Account2Account debits a bank account directly, and Windcave have told me that they cannot provide a full test environment for me to test in. Merchants have told me that it works, but I have not tested it.

I get an SSL error when my form attempts to connect with Windcave

This is a common problem in local testing environments. Read how to fix your website SSL configuration.

Can I use this plugin on any shared-hosting environment?

The plugin will run in shared hosting environments, but requires the following PHP modules enabled (talk to your host). Both are typically available because they are enabled by default in PHP, but may be disabled on some shared hosts.

  • XMLWriter
  • SimpleXML

Are there any filter hooks?

Developers can use these filter hooks to modify some invoice properties. Each filter receives a string for the field value, and the Gravity Forms form array.

  • gfdpspxpay_invoice_ref for modifying the invoice reference
  • gfdpspxpay_invoice_trans_number for modifying the invoice transaction reference; NB: must be unique for PxPay account!
  • gfdpspxpay_invoice_txndata1 for setting the TxnData1 field
  • gfdpspxpay_invoice_txndata2 for setting the TxnData2 field
  • gfdpspxpay_invoice_txndata3 for setting the TxnData3 field

Developers can run processes on these actions (e.g. load classes required to handle invoice presentation):

  • gfdpspxpay_process_confirmation
  • gfdpspxpay_process_confirmation_parsed
  • gfdpspxpay_process_approved
  • gfdpspxpay_process_failed
