## Description

Coriunder Payment Gateway connects WooCommerce stores to the Coriunder hosted payment
service. During checkout, customers are redirected to Coriunder to enter their payment
details and are then returned to the store.

The plugin supports classic checkout, Cart and Checkout Blocks, and High-Performance
Order Storage (HPOS). A Coriunder merchant account, merchant ID, personal hash, 
and HTTPS-enabled store are required.

### External services

This plugin relies on Coriunder, a third-party payment service provided by Coriunder
Limited. It is required to take payments: without it the plugin does nothing. The
plugin connects to two Coriunder services.

**1. Coriunder hosted payment page** (default `https://uiservices.coriunder.cloud/
hosted/default.aspx`; the URL is configurable in the gateway settings)

 * What it is for: the customer enters their payment details on this page instead
   of on your store, and the payment is processed there.
 * When: each time a customer places an order and chooses Coriunder as the payment
   method. The customer’s browser is redirected to the page.
 * What is sent: your merchant ID, the order number, amount and currency, the payment
   type (capture or authorization), the payment description, the payment-page language,
   the order’s UTM source (if one was recorded at checkout), the return and notification
   URLs of your store, and the customer’s name, email address, phone number, billing
   address, postal code, city and country, together with a signature of these values.

**2. Coriunder transaction status service** (`https://process.coriunder.cloud/member/
getStatus.asp`)

 * What it is for: confirming that a payment really happened, with the right amount
   and currency, before the WooCommerce order is marked as paid or failed.
 * When: each time Coriunder returns the customer to your store or sends a payment
   notification to your store.
 * What is sent: your merchant ID, the order number and a signature. No customer
   data is sent.

## Installation

 1. Upload the plugin ZIP through **Plugins > Add Plugin > Upload Plugin**, or copy
    the `coriunder-payment-gateway` directory to `/wp-content/plugins/`.
 2. Activate **Coriunder Payment Gateway** in WordPress.
 3. Go to **WooCommerce > Settings > Payments > Coriunder Gateway**.
 4. Enter the merchant ID, personal hash, and hosted payment URL supplied by Coriunder.
 5. Choose the payment action and payment-page language, then enable and save the gateway.

## FAQ

### Does the gateway support 3-D Secure?

3-D Secure availability depends on the configuration of your Coriunder merchant 
account. Contact Coriunder to enable or confirm this feature.

### Does this plugin collect card details?

No. Customers enter their payment details on the Coriunder hosted payment page. 
The plugin sends the order and billing information described in the External services
section.

### Which checkout types are supported?

The plugin supports the classic WooCommerce checkout and WooCommerce Cart and Checkout
Blocks.

### How do I refund an order?

Refunds are issued from your Coriunder merchant dashboard. After refunding the transaction
there, open the order in WooCommerce, click **Refund**, enter the amount and choose**
Refund manually** to record it on the order (and restock items if needed).

   before an order can be marked paid or failed
 * Security – Callback verification now checks merchant, order, transaction, amount,
   currency and transaction type where available
 * Security – Debug logs no longer write full payment URLs, customer PII or callback
   signatures
 * Security – Base URL is restricted to a valid HTTPS URL
 * Compatibility – HPOS order metadata now uses the WooCommerce order CRUD API

   currency
 * Compatibility – Updated compatibility metadata for WordPress 7.1 / 7.0.4 and 
   WooCommerce 11.0.1 / 10.9.4

   captured payments

#### Version 1.3.0 – 24082026

 * Feature – Gateway Logo: the logo shown on the settings screen and at checkout
   is now uploaded by the merchant through the WordPress media library. A “Select
   image” / “Remove” picker was added to the General section
 * Change – No logo is bundled with the plugin any more. When no logo has been uploaded,
   the settings header and the checkout payment method render without an image instead
   of falling back to the built-in Coriunder logo
 * Change – Removed the “Test & Debug” sandbox settings: Enable Test Mode, Test 
   Merchant ID, Test Personal Hash and Test Base URL are gone. The gateway always
   uses the Live Credentials
 * Change – Removed the “Test mode is active” admin notice and the “Test Mode Active”
   badge from both the classic and Blocks checkout
 * Change – Debug Logging kept, moved into its own “Debug” section
 * Change – Blocks checkout availability and webhook signature verification now 
   read the live Personal Hash directly; the sandbox branch was removed

   before use

 * Fix – process_payment(): replaced $woocommerce->cart->empty_cart() with WC()-
   >cart->empty_cart()
 * Fix – Orders no longer stuck in pending after payment: reply code and order status
   are now resolved on the thank-you page via the woocommerce_thankyou_coriunder
   hook, which reads Coriunder’s redirect params (replyCode, trans_id, trans_refNum)
   and calls payment_complete() immediately when the customer returns
 * Fix – Signature verification corrected for both the redirect and webhook: Coriunder
   sends raw base64 (not URL-encoded), and the redirect uses SHA256(reply_code .
   trans_id . personal_hash)

   General, Live Credentials, Test & Debug sections)

   2.1 AA compliant focus management)
 * Improvement – All form controls now have explicit labels, aria-describedby help
   text, and visible focus rings
 * Improvement – Settings sections use semantic HTML (section + aria-labelledby,
   role attributes)
 * Improvement – Hash fields use type=”password” and autocomplete=”new-password”
   to prevent credential exposure
 * Improvement – Test-mode banner shown inline on settings page when sandbox is 
   active

   ≤782px)

#### Version 1.1.7 – 09042026
