<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>

<p><strong>Put your downloads in the spotlight by giving them a sale price!</strong></p>
<p>Numerous studies have shown that people are more likely to buy a product, no matter what, if it is has a discount. Specially if it is something they already wanted to have. The discount will trigger the potential customer to buy your products fast.</p>
<p>Setting up a discount correctly is important, of course you can just lower the price, but then most people will not know the product is discounted. With EDD Sale Price the regular price will be shown with a strikethrough so people will see how much it regularly costs, and what the new sale price is!</p>
<p>Works with both simple downloads and variable priced downloads.</p>
<p><strong>Look at the screenshots!</strong></p>
<p><strong>Feature requests, ratings and donations are welcome and appreciated!</strong></p>
