This plugin adds Piraeus Bank paycenter as a payment gateway for WooCommerce. A contract between you and the Bank must be previously signed. Based on original plugin “Piraeus Bank Greece Payment Gateway for WooCommerce” by emspace.gr [https://wordpress.org/plugins/woo-payment-gateway-piraeus-bank-greece/] and 
 on “Piraeus Bank WooCommerce Payment Gateway” by enartia [https://el.wordpress.org/plugins/woo-payment-gateway-for-piraeus-bank/] 
It uses the redirect method, and SSL is not required.
The main diferrences from the original versions that lead to a creation of a new plugin, rather than improving those in existance are: 
* The code has been rewritten and altered significally to implement an object oriented approach and rich commenting has been added 
* It is compatible with the Polylang plugin. This allows a smooth integration with multilingual websites. Moreover, based on the language the visitor chooses to view the checkout page, it presents the same language on Piraeus Bank website. Currently supported languages greek, english 
* Transaction Responses are now stored as custom post types and are easily accessible from the dashoboard. This makes the communication with the bank easy in case an error occurs with the completion of a transaction 
* It uses SESSIONS to store information instead of burdening the database
Requires SOAP installed in the server / hosting.
<h3>Important Notice</h3>
This plugin is compatible with the change in the way that the ”Hash Key” is generated by Piraeus Bank.
<h3>Features</h3>
Provides pre-auth transactions and free installments. 
Note: Piraeus Bank will stop accepting pre-authorized payments in the future. It is best to keep this option disabled
<h3>HTTP Proxy</h3>
In case your server doesn’t provide a static IP address for your website, you can use an HTTP Proxy for outgoing requests from the server to the bank. The following fields need to be filled for http proxying: 
HTTP Proxy Hostname: Required. If empty then HTTP Proxy is not used. 
HTTP Proxy Port: Required if HTTP Proxy Hostname is filled. 
HTTP Proxy Login Username/Password: Optional.

Adds Piraeus Bank paycenter as a payment Gateway for WooCommerce

This plugin adds a WooCommerce payment gateway for Opayo Form integration (Sage Pay Form / Elavon hosted form). Customers pay on Opayo’s secure page, so your site does not collect or store card numbers, which reduces PCI scope compared with on-site card fields.
How it works:
<ul>
<li>At checkout, the shopper is redirected to Opayo with an encrypted payload (Crypt) built from the order.</li>
<li>After payment, Opayo sends the customer back to your site; the plugin decrypts the response, checks the order and amount, and completes the order when the payment is successful.</li>
<li>Supports classic checkout and registers with WooCommerce Blocks checkout when the block checkout is enabled.</li>
</ul>
Requirements:
<ul>
<li>WordPress and WooCommerce (see readme headers for tested versions).</li>
<li>An Opayo account with Form integration and credentials from MyOpayo (Vendor name, Encryption password).</li>
<li>HTTPS is strongly recommended for checkout and payment return URLs.</li>
</ul>
Notes:
<ul>
<li>Uses Elavon’s current Form register hosts (<code>sandbox.opayo.eu.elavon.com</code> / <code>live.opayo.eu.elavon.com</code>) and VPSProtocol 4.00. Override the register URL with the <code>woocommerce_sagepayform_register_url</code> filter if your account requires a different endpoint.</li>
<li>Override the return/notify URL with <code>woocommerce_sagepayform_notify_url</code> if needed.</li>
</ul>
Use Elavon / Opayo’s official documentation for account setup, test cards, and regional rules.
