AcquirerOS Payment Gateway for WooCommerce

AcquirerOS Payment Gateway for WooCommerce adds the AcquirerOS-compatible payment method to WooCommerce, with support for both classic checkout and the WooCommerce Checkout Block.

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

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.

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.
