SagePay Form Gateway for MarketPress

SagePay Form Gateway Plugin for accepting payments on your MarketPress Store.

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.
