SaturnShift – USDC, USDT & Card Payments for WooCommerce
SaturnShift for WooCommerce is a connector, not a second dashboard. It links your store to your SaturnShift account and then stays out of the way:
- Connect once, no keys. Click « Connect with SaturnShift », approve, and the plugin pulls your enabled payment methods (cards, ACH, USDC, USDT), branding and surcharge rules, and registers its webhook automatically. There are no API keys or secrets to copy.
- Same checkout. At « Place Order » the buyer is sent to your hosted SaturnShift checkout, the exact one you already use, then returned to your order page.
- Orders stay in sync. Signed webhooks move each order between Pending, Paid, Failed, Expired and Refunded.
- On-chain receipt. Crypto orders show the settlement network and a block explorer link on the order, in « My Account », and in order emails.
- Manage everything in SaturnShift. Refunds, reporting, invoices, settlements, payment links, analytics, customers and QuickBooks accounting sync all live in your SaturnShift dashboard.
You need a SaturnShift account to use this plugin. You can create one for free during the connect step if you don’t have one yet.
External services
This plugin connects your store to SaturnShift, a third-party payment service, to create checkouts, keep orders in sync, and process refunds. It cannot function without this connection. The following describes what is sent and when.
SaturnShift API (https://api.saturnshift.io)
Used server-to-server for all payment operations.
- When a customer places an order, the plugin sends the order amount, currency, order id and your store’s return URLs to create a hosted checkout.
- On connect, the plugin registers a webhook URL on your store and fetches your merchant configuration (enabled payment methods, branding, surcharge rules).
- When you issue a refund, the plugin sends the order reference and refund amount.
- SaturnShift sends signed webhooks back to your store to update order status.
No customer payment card numbers or bank details pass through your WordPress site; those are entered directly on SaturnShift’s hosted checkout.
SaturnShift authorization (https://app.saturnshift.io)
When you click « Connect with SaturnShift », your browser is redirected to app.saturnshift.io to sign in and approve the connection (OAuth 2.0 with PKCE). No credentials are entered into or stored by WordPress.
