Windcave (formerly Payment Express or DPS) is a payment gateway (the service that processes card payments). It lets customers pay in your Rocketspark shop with a credit or debit card. Funds are usually in your bank account within one business day. This guide covers how to apply for Windcave, get approved and connect it to your online store.
Setting up Windcave card payments in your online store
Before you start, you'll need a merchant account with your bank (a business account that lets you accept card payments). If you already take card payments in person, you may already have one. If not, Windcave can help you get one.
Setup has three stages: apply through your Dashboard, get approved by Windcave and your bank, then enter your Windcave details in Rocketspark.
Step 1: Apply for a Windcave account
- In your Dashboard, go to Manage Store → Payment Gateways.
- Select Windcave (Payment Express) and click Setup new account.
-
Fill in the application form. Some details may already be filled in for you. If you'd also like EFTPOS for in-person payments, say so on the form.
Step 2: Get your site ready for approval
A Windcave account manager will contact you within 2 business days. Before your bank approves the account, check your site has:
- Terms and conditions that are valid and visible on your site
- A business address showing on your site
-
Your website toggle set to "on". If your site isn't live yet, send Windcave your trial URL, e.g.
yourdomainname.rocketspark.co.nz -
Bank Deposit / Direct Credit turned on for now, so test orders can go through while you wait
Step 3: Connect Windcave to Rocketspark
Once you're approved, Windcave will send you a PxPay User ID and a PxPay Key.
- Go back to Manage Store → Payment Gateways in your Dashboard.
- Next to Windcave (Payment Express), click Edit settings.
- Enter your PxPay User ID and PxPay Key.
- Turn the Windcave (Payment Express) toggle from red to green to switch it on.
- Enable Payment Express by changing the toggle from red to green.
Saving cards and recurring payments with Windcave
If you'd like to save customer cards or take recurring payments, these need to be set up manually by both Rocketspark and Windcave:
- Email support@rocketspark.com and ask us to set up card saving and recurring billing on your site.
- Email support@paymentexpress.com and ask Windcave to switch on recurring billing for your account.
Note: If you're planning to sell subscriptions, we recommend Stripe. It works fully with Rocketspark subscriptions without manual setup.
Tips and things to watch out for
- Keep Bank Deposit / Direct Credit on until Windcave is live, so you can still take orders while you wait.
- Copy your PxPay User ID and Key exactly as Windcave sends them. A missing character will stop payments going through.
- Make sure the Windcave (Payment Express) toggle is green. Your details can be saved and still not show at checkout if the toggle is off.
