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.

Upload the plugin to `/wp-content/plugins/` and activate it (or install it from the WordPress plugin directory). WooCommerce must be installed and active. 2. Go to WooCommerce > Settings > Payments > SaturnShift. 3. Click “Connect with SaturnShift”. Sign in (or create a free account), choose a plan if prompted, and approve. You’re returned to WooCommerce connected, your config is pulled in, and the webhook is registered automatically. 4. The gateway is enabled on connect. Adjust the title/description if you like. ## FAQ ### Do I need API keys? No. Connecting uses a one-click OAuth approval (the same pattern as “Sign in with” buttons). There are no keys or secrets to copy or store. ### Do I configure payment methods here? No. Whatever you enable in SaturnShift (cards, ACH, USDC, USDT) is what shows at checkout. The plugin mirrors your SaturnShift configuration. ### Which currencies are supported? Orders are settled in USD. If your store currency isn’t supported, the plugin shows a notice and hides itself at checkout until you switch to a supported one. ### Where do I issue refunds? You can click Refund on the WooCommerce order, which forwards the request to SaturnShift, or refund directly in your SaturnShift dashboard. Either way the WooCommerce order is updated to Refunded when the refund settles. ### Is customer card or bank data stored in WordPress? No. Payment details are entered on SaturnShift’s hosted checkout, never on your WordPress site. ### Does it work with the block-based checkout? Yes. The plugin supports both the classic and block (Cart & Checkout blocks) checkout experiences, and is compatible with High-Performance Order Storage. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “SaturnShift – USDC, USDT & Card Payments for WooCommerce” is open source software.
