For most merchants, Redirect / Hosted Checkout is the recommended payment mode. Customers complete card entry on the hosted payment page instead of entering card details directly into WordPress. S2S / Direct API is also available as an advanced integration option for merchants whose payment environment and compliance requirements support direct card-data processing. #### Multi-Gateway support Version 2.3.0 registers four independent WooCommerce payment methods from one plugin: * AcquirerOS – Credit Card: Redirect / Hosted Checkout or S2S / Direct API. * AcquirerOS – PayPal: Redirect / Hosted Checkout only, with a single Hosted Checkout URL. * AcquirerOS – Apple Pay: Redirect / Hosted Checkout only, with a single Hosted Checkout URL. * AcquirerOS – Google Pay: Redirect / Hosted Checkout only, with a single Hosted Checkout URL. Each payment method has its own Merchant Number, Gateway Number, Signature Key, endpoint and optional merchant-selected checkout logo. The Credit Card payment method keeps the original `acquireros_gateway` ID and existing settings for backwards compatibility. Availability of PayPal, Apple Pay and Google Pay depends on the merchant’s AcquirerOS/ acquiring configuration. Apple Pay and Google Pay may also require payment-provider, merchant, domain, device or browser eligibility. Each gateway defaults to no logo. Merchants can optionally upload their own authorized payment-method image to the WordPress Media Library and select it per gateway. No third-party payment-brand artwork is bundled with the plugin. #### Payment modes * Redirect / Hosted Checkout (Recommended): WooCommerce sends the required order and customer information to the configured Hosted Checkout endpoint and redirects the customer to the returned secure payment URL. Card number, expiry date and CVV/CVC are not collected by this plugin in Redirect mode. * S2S / Direct API (Advanced): Card number, expiry date and CVV/CVC are entered during WooCommerce checkout and transmitted server-to-server to the configured payment endpoint for payment processing. Merchants using this mode are responsible for confirming their PCI DSS scope and compliance obligations with their payment provider and qualified compliance advisers. #### WooCommerce integration The plugin integrates with standard WooCommerce payment and order workflows and includes support for: * Classic WooCommerce checkout. * WooCommerce Checkout Block. * High-Performance Order Storage (HPOS). * Redirect / Hosted Checkout payment flows. * S2S / Direct API payment flows. * 3D Secure payment returns. * Asynchronous payment notifications. * WooCommerce order status updates. * Duplicate callback protection. * Diagnostic logging for troubleshooting. #### External service This plugin connects to the payment endpoint configured by the merchant in WooCommerce > Settings > Payments > AcquirerOS. This external service is required to create and process payment transactions. Depending on the selected payment mode and transaction requirements, information sent to the configured payment endpoint can include: * Order number and transaction identifiers. * Order amount and currency. * Product and order item information. * Billing and shipping details. * Customer name, email address and phone number. * Customer IP address. * Browser and user-agent information. * Payment return and notification callback URLs. In S2S / Direct API mode only, card number, expiry date and CVV/CVC are also transmitted to the configured payment endpoint for payment processing. AcquirerOS service: https://acquireros.com/ AcquirerOS Privacy Policy: https://acquireros.com/privacy/ AcquirerOS Terms of Service: https://acquireros.com/terms/ Merchants should publish appropriate privacy disclosures and ensure that their use of the configured payment service complies with applicable laws, contractual requirements and payment-card security requirements. #### Security notes * Redirect / Hosted Checkout is the recommended mode for most merchants. * Hosted Checkout is the default payment mode for new installations. * Card numbers and CVV/CVC are not stored in WordPress order metadata by this plugin. * Card numbers and CVV/CVC are not written to the plugin diagnostic log. * In Redirect mode, card details are not collected by the plugin in WordPress. * Payment callbacks use per-order random callback tokens. * Asynchronous notification callbacks require a valid gateway signature. * Callback merchant, gateway, order number, amount and currency are validated before an order is updated. * Asynchronous notification callbacks accept POST requests only. * Configured payment endpoints must use public HTTPS URLs. * Duplicate successful callbacks are handled idempotently through WooCommerce payment status checks. * Payment requests use the WordPress HTTP API. ## Installation 1. Install and activate WooCommerce. 2. Install and activate AcquirerOS Payment Gateway for WooCommerce. 3. Go to WooCommerce > Settings > Payments. 4. Configure and enable AcquirerOS – Credit Card, AcquirerOS – PayPal, AcquirerOS – Apple Pay and/or AcquirerOS – Google Pay. 5. Enter the Merchant Number, Gateway Number and Signature Key for each enabled payment method. Credit Card can use Payment Gateway URL and Hosted Checkout URL; PayPal, Apple Pay and Google Pay use only Hosted Checkout URL. 6. Optionally choose a Payment Method Logo from the WordPress Media Library for each gateway. 7. For Credit Card, choose Redirect / Hosted Checkout (Recommended) or S2S / Direct API (Advanced). 8. Test every enabled payment method before production use. For production use, verify that payment creation, Hosted Checkout or 3D Secure returns, asynchronous notifications and WooCommerce order status updates are working correctly for your integration. ## FAQ ### Can Credit Card, PayPal, Apple Pay and Google Pay be enabled together? Yes. Version 2.3.0 registers them as separate WooCommerce payment methods from the same plugin. Each one can be enabled and configured independently. ### Do PayPal, Apple Pay and Google Pay use S2S card fields? No. In 2.3.0, PayPal, Apple Pay and Google Pay use Redirect / Hosted Checkout only. Credit Card can use Hosted Checkout or S2S / Direct API. ### Does enabling PayPal, Apple Pay or Google Pay automatically activate those services? No. Your AcquirerOS/acquiring configuration must support the selected payment method. Apple Pay and Google Pay may require additional merchant, domain, device, browser or payment-provider configuration. ### How do I add a payment method logo? By default no logo is displayed. Upload an image you are authorized to use under Media > Add New, then open WooCommerce > Settings > Payments, select the AcquirerOS gateway, and use Payment Method Logo > Select Image. The image is stored in the merchant’s WordPress Media Library and displayed next to that payment method at checkout. The AcquirerOS plugin does not bundle Visa, Mastercard, PayPal, Apple Pay, Google Pay or other third-party brand artwork. ### Can the Hosted Checkout notice be customized? ### Can the checkout description contain text and images? Yes. Checkout description is empty by default. Merchants can add formatted text, links and images selected from the WordPress Media Library. The content is sanitized with WordPress allowed post HTML before it is displayed at checkout. ### Which payment mode should I use? Redirect / Hosted Checkout is recommended for most merchants because card details are entered on the hosted payment page rather than directly in WordPress. S2S / Direct API should only be enabled when your organization, payment provider and compliance environment are prepared for the additional cardholder-data security requirements. ### Does the plugin store card numbers or CVV/CVC? No. The plugin does not save card numbers or CVV/CVC to WordPress order metadata or its diagnostic logs. In Redirect / Hosted Checkout mode, card details are not collected by the plugin in WordPress. In S2S / Direct API mode, card details are used to create the payment request and are transmitted to the configured payment endpoint, but they are not stored in WordPress order metadata by this plugin. ### Does it support WooCommerce Checkout Block? Yes. AcquirerOS supports the WooCommerce Checkout Block as well as classic WooCommerce checkout. ### Is HPOS supported? Yes. The plugin uses WooCommerce order APIs and declares compatibility with High- Performance Order Storage (HPOS). ### Does it support 3D Secure? The plugin supports payment flows that return customers to WooCommerce after 3D Secure authentication when this is required by the configured payment service. Actual 3D Secure availability and behavior depend on your AcquirerOS merchant configuration and payment provider. ### Does it support payment notifications? Yes. The plugin supports asynchronous payment notifications through WooCommerce callback endpoints. Notification requests are validated before the corresponding WooCommerce order is updated. ### Where are diagnostic logs? When diagnostic logging is enabled, logs are available under WooCommerce > Status > Logs using the AcquirerOS gateway log source. Diagnostic logs are intended for troubleshooting and do not include card numbers or CVV/CVC. ### Where do I get my AcquirerOS credentials? Your payment credentials and endpoint information are provided as part of your AcquirerOS merchant integration.
