<p>Paymentfor Gateway for WooCommerce is a free plugin that integrates Payment for, Inc. payment services with WooCommerce, enabling secure acceptance of multiple payment methods. To use this plugin, you must have an active merchant account with Payment for, Inc. The plugin operates in compliance with PCI DSS standards and supports EMV 3-D Secure 2.0 authentication for enhanced security.<br />
Supported payment methods include credit card payments (non-pass-through token-based or link-based), convenience store online payments, and PayPay mobile wallet payments. Recurring subscription payments are supported through the WooCommerce Subscriptions plugin.</p>
<h3>Minimum Requirements</h3>
<ul>
<li>WordPress 5.6 or newer.</li>
<li>PHP 7.4 or newer.</li>
<li>WooCommerce 3.0 or newer.</li>
<li>WooCommerce Subscriptions tested up to 8.2.1 (for subscription payments).</li>
<li>SSL certificate required (SHA2 algorithm, TLS 1.2 only).</li>
<li>Merchant account with Payment for, Inc.</li>
</ul>
<h3>Build Process</h3>
<p>This plugin includes minified JavaScript files in the <code>build/</code> directory for the block-based checkout functionality. These files are generated using @wordpress/scripts and webpack.</p>
<p>The source files for the block checkout are developed using React and modern JavaScript, then compiled into the production-ready files you see in the <code>build/</code> directory.</p>
<p><strong>Build dependencies:</strong><br />
– Node.js and npm<br />
– @wordpress/scripts package</p>
<p>If you need to rebuild the JavaScript files from source, you would need to set up a Node.js development environment with @wordpress/scripts. However, for normal plugin use, this is not necessary as the compiled files are included.</p>
<h3>Setup</h3>
<p>Before using this plugin, you must have an active merchant account with Payment for, Inc. Contact Payment for, Inc. at https://www.paymentfor.com/ to apply.<br />
Once approved, you will receive an IP Code and IP Password required for configuration.<br />
To configure each payment method, go to WooCommerce > Settings > Payments and click Manage for the desired payment method. Enter your credentials and configure the settings as needed. Save your changes.<br />
For convenience store and PayPay payments, you must register payment notification URLs with Payment for, Inc. to receive payment confirmations. The required URLs are displayed in the payment settings.</p>
<h3>Payment Processing</h3>
<p>All payment operations (sales confirmation, cancellation, refund) must be performed through the WooCommerce order management interface, not through the Payment for, Inc. merchant dashboard. Performing operations outside of WooCommerce may cause synchronization failures.<br />
Do not delete order records before completing payment adjustments, as this will prevent WooCommerce from processing payment modifications. If an order is deleted, contact Payment for, Inc. merchant support for transaction adjustments.</p>
<h3>Testing</h3>
<p>Verify all payment settings are configured correctly before testing. Obtain test card numbers from the Payment for, Inc. merchant dashboard. Complete test purchases using the test cards and verify transactions appear in the Payment for, Inc. merchant dashboard. Test payment operations including sales confirmation and cancellation. If testing with real cards, always cancel the test transaction afterward.</p>
<h3>Important Notes</h3>
<p>SSL certificate installation is mandatory. Signature algorithm must be SHA2 and communication protocol must be TLS 1.2 only (TLS 1.3 not supported). Contact your hosting provider for SSL configuration verification.<br />
This plugin complies with PCI DSS standards. Credit card information is never stored on your server. It is securely transmitted and stored only in Payment for, Inc. systems.<br />
For convenience store and PayPay payments, payment completion notifications are only received if notification URLs are properly registered with Payment for, Inc.</p>
