Gravity Forms Windcave enables you to store two pairs of User ID and User Key credentials. When you first sign up for a PxPay account with Windcave you will likely be issued development or testing sandbox 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.

When you create a feed for your form, you select which mode you want to use for transactions: Live or Test. Test mode uses your sandbox credentials, allowing you to test your forms without processing real transactions. You must use special test credit card details when using the test environment.
