This add-on connects Gravity Forms to Opayo Direct (formerly Sage Pay Direct), so you can take payments inside your forms without sending shoppers to an external payment page.
What you get
<ul>
<li>On-form card fields: number, expiry, and security code are submitted securely to Opayo using the Direct integration.</li>
<li>Test and live modes, plus global settings for vendor name and transaction type (Payment, Deferred, or Authenticate).</li>
<li>Optional per-form feed overrides for vendor name, mode, and transaction type when you need different Opayo settings per form.</li>
<li>3-D Secure support: when Opayo requires authentication, the shopper is guided through the challenge and returns to your site to complete the payment.</li>
<li>Gravity Forms payment features: product and donation pricing, feed conditional logic (where configured in Gravity Forms), delayed notifications until payment succeeds, and payment-related notification events.</li>
</ul>
Requirements
<ul>
<li>Gravity Forms 2.5 or newer with the Payment Add-On framework (required by this plugin).</li>
<li>An Opayo merchant account with Direct enabled.</li>
<li>HTTPS (SSL) on your site. Card data is collected on your domain; you are responsible for PCI DSS compliance for your environment.</li>
</ul>

Opayo Direct Gateway for Gravity Forms

Accept card payments on Gravity Forms with Opayo (Elavon) Direct—customers stay on your site while cards are processed through your Opayo account.

This plugin adds Opayo Direct as a WooCommerce payment gateway so customers can pay by card without leaving your store.
Highlights
<ul>
<li>On-site card entry using the standard WooCommerce credit card form (customisable card fields).</li>
<li>Supports WooCommerce Checkout Block (cart/checkout blocks) in addition to classic checkout.</li>
<li>Declares compatibility with WooCommerce HPOS (High-Performance Order Storage / custom order tables).</li>
<li>PSD2, Strong Customer Authentication (SCA), and 3D Secure v2 flows for eligible transactions.</li>
<li>Vendor test and live modes, configurable card types, and optional shipping data to Opayo.</li>
</ul>
Opayo Direct is a server-to-server integration: you control branding and the checkout experience while card data is handled according to your PCI scope. You need an Opayo merchant account with Direct integration enabled.
Requirements
<ul>
<li>WordPress and WooCommerce installed and up to date.</li>
<li>A valid SSL certificate (HTTPS) on your checkout site.</li>
<li>PCI DSS compliance is your responsibility for how you collect and transmit card data; consult Opayo and your QSA as needed.</li>
</ul>
