<h3>External Services</h3>
<p>This plugin relies on the Payment4 API, a third-party external service, to process cryptocurrency payments. The plugin will not function without connecting to this service.</p>
<h4>What is the Payment4 API?</h4>
<p>Payment4 (https://payment4.com) is a cryptocurrency payment gateway service that processes crypto transactions, monitors blockchain confirmations, and manages payment verification.</p>
<h4>When does the plugin connect to Payment4 services?</h4>
<p>The plugin connects to Payment4 external services in the following situations:</p>
<ol>
<li><strong>During Checkout</strong> – When a customer selects Payment4 as their payment method and proceeds to pay</li>
<li><strong>Payment Verification</strong> – When verifying that a cryptocurrency payment has been received and confirmed on the blockchain</li>
<li><strong>Payment Callbacks</strong> – When Payment4 sends webhook notifications about payment status updates</li>
<li><strong>Language Files</strong> – When loading translation files for the plugin interface</li>
</ol>
<h4>What data is transmitted?</h4>
<p>When processing payments, the following data is sent to Payment4 services:</p>
<ul>
<li>Order amount and currency</li>
<li>Order ID and description</li>
<li>Customer email address (optional, for payment notifications)</li>
<li>Return and callback URLs for your website</li>
<li>API credentials (API key) for authentication</li>
</ul>
<p>No sensitive financial information (credit card details, bank accounts, etc.) is transmitted. Cryptocurrency transactions are handled directly on the blockchain.</p>

<p>This plugin requires <a href="https://wordpress.org/plugins/easy-digital-downloads/" rel="ugc">Easy Digital Downloads</a>.</p>
<p>If you’ve created a custom landing page or purchase funnel, hide the default product page of an Easy Digital Downloads product from users, and redirect them to your funnel. This allows you to optimize your purchase funnel and increase revenue.</p>
<p>EDD Hide Download allows you to:<br />
1. Hide a download so it doesn’t appear on the custom post type archive page, anywhere where the [downloads] shortcode is being used, or any custom query on a page template<br />
1. Prevent direct access to the download product page. The browser will redirect the user to the site’s homepage.<br />
1. Do a combination of hiding the download and preventing direct access to it</p>
<p>This plugin is extremely useful in the following situations:</p>
<ol>
<li>You’ve created a product landing page and inserted a buy now button to your product. Since the landing page contains all the required product information, you can hide the product on the rest of your site and even prevent direct access to it.</li>
<li>You’ve added a product (eg support package) that shouldn’t sit with your other products you have listed. In this case we can simply hide it from appearing with the other products and insert it where we’d like it to appear using the shortcode.</li>
</ol>
<p><strong>Filter example</strong></p>
<p>Example filter of how you can change the redirect based on the download ID. Copy this function to your child theme’s functions.php or custom plugin</p>
<pre><code>function sumobi_custom_edd_hide_download_redirect( $url ) {
    // download has ID of 17
    if ( '17' == get_the_ID() ) {
        $url = 'http://easydigitaldownloads.com'; // redirect user to another external URL
    }

    // download has ID of 15
    if( '15' == get_the_ID() ) {
        $url = get_permalink( '8' ); // redirect to another download which has an ID of 8
    }

    // return our new URL
    return $url;
}
add_filter( 'edd_hide_download_redirect', 'sumobi_custom_edd_hide_download_redirect' );
</code></pre>
<p>Example filter of how you can globally change the redirect. Copy this function to your child theme’s functions.php or custom plugin</p>
<pre><code>function sumobi_custom_edd_hide_download_redirect_url( $url ) {
    $url = get_permalink( '8' ); // redirect to another download, post or page

    return $url;
}
add_filter( 'edd_hide_download_redirect', 'sumobi_custom_edd_hide_download_redirect' );
</code></pre>
