External services
This plugin relies on the following external services to process payments. A Saga Payments merchant account is required.
Saga Payments API
All payment operations (order creation, payment verification, refunds, captures, voids, and subscription management) are handled through the Saga Payments API proxy server. When a customer initiates a checkout, order data including amount, currency, line items, and customer billing/shipping information is sent to this service via server-side HTTP requests.

Saga Payments Merchant Dashboard and Documentation
The plugin settings screen links store administrators to Saga Payments dashboard and documentation pages for API key, webhook, and product catalogue setup. These links open only when an administrator clicks them. No customer or payment data is sent automatically by these documentation links.

Saga OTP Verification Service
When a guest customer pays with a previously saved card, the plugin sends a one-time password (OTP) verification email via a Cloudflare Worker. Only the customer’s email address, a generated OTP code, the store name, and the cart total are sent in the request. No card data is transmitted. The OTP email is delivered via the worker using the Resend email service.

Surfboard Online SDK
The payment form displayed on your checkout page is rendered by the Surfboard Online SDK. This JavaScript library is loaded from an external server into the customer’s browser and handles the secure payment UI including card input fields, Vipps/MobilePay popups, Klarna widget, and Apple Pay / Google Pay buttons. Card data is entered directly into Surfboard-hosted iframes and never touches your server.

Surfboard Hosted Payment Page
When the plugin is configured in redirect mode, or for certain subscription flows, the customer’s browser is redirected to a hosted payment page operated by Surfboard Payments. The order amount, currency, and return URLs are passed via the redirect. All payment data is entered on the hosted page.

Surfboard Vipps/MobilePay Intermediary
For Vipps and MobilePay payment flows, the Surfboard SDK loads an intermediary page in an iframe to handle the mobile payment authorization. This is managed automatically by the Surfboard Online SDK and serves as the bridge between your store and the Vipps/MobilePay apps.

Google Pay API
When Google Pay is enabled as a payment method, the Google Pay JavaScript SDK is loaded in the customer’s browser to render the Google Pay button and handle the payment sheet. Payment token data is returned to your store and forwarded to the Saga Payments API for processing.
SDK URL: https://pay.google.com/gp/p/js/pay.js

QR Code Generation
For Swish payments, if the payment gateway does not return a pre-rendered QR code image, the plugin generates a QR code locally using the bundled qrcode-generator library (MIT license, by Kazuhiko Arase). No external service is called for QR code generation.
Saga Checkout SDK (Diagnostics Only)
The plugin diagnostics page displays the configured SDK endpoint for admin troubleshooting purposes. The actual payment SDK loaded during checkout is the Surfboard Online SDK documented above.

Saga Product Sync API
If the optional product synchronization feature is enabled, the plugin sends product data (name, description, price, SKU, images, categories) from your WooCommerce catalog to the Saga Payments product API for catalogue management. This is an opt-in feature configured in the plugin settings.

Payment Method Logos
Payment method logos (Visa, Mastercard, Amex, Vipps, Klarna, Apple Pay, Google Pay, Swish, MobilePay) are bundled locally within the plugin in SVG format. No external CDN is used for logo display.
SVG files and inline SVG markup use the standard SVG namespace URI http://www.w3.org/2000/svg and xlink namespace URI http://www.w3.org/1999/xlink as static XML identifiers; these are not external network requests.
