SaleMint Paddle Checkout for WooCommerce connects your WooCommerce store to <a href="https://paddle.com" rel="nofollow ugc">Paddle</a>, a merchant-of-record payment platform built for digital products. Paddle handles the checkout, tax calculation, and invoicing, while this plugin keeps your WooCommerce orders fully in sync.
<h4>How it works</h4>
When a customer places an order, the plugin opens Paddle’s hosted checkout (modal or full-page). After the customer completes payment, the Paddle transaction ID is captured and attached to the WooCommerce order. The plugin then fetches the authoritative order totals from Paddle — including any tax Paddle applied — and updates the WooCommerce order to match, so your records are always accurate.
<h4>Key features</h4>
<ul>
<li>Classic checkout & WooCommerce Blocks — Works with both the classic WooCommerce checkout and the modern block-based checkout.</li>
<li>Modal or full-page checkout — Choose between an overlay modal or a full-page Paddle checkout, configurable from the gateway settings.</li>
<li>Sandbox / live mode — Toggle between Paddle’s sandbox environment for testing and the live environment for production, without touching any code.</li>
<li>Digital-only enforcement — The Paddle payment option is automatically hidden whenever the cart contains a physical product that requires shipping. This prevents it from appearing for orders Paddle cannot fulfil.</li>
<li>Paddle tax categories — Assign a Paddle tax category (e.g. standard, digital-goods, ebooks, SaaS, software) to products, with a configurable store-wide default. Supports all 13 Paddle tax classifications.</li>
<li>Coupon sync — WooCommerce coupons applied at checkout are forwarded to Paddle as discounts, so the transaction amount in Paddle always reflects the discounted total.</li>
<li>Cart fee sync — Extra fees added to the cart (e.g. handling fees or surcharges) are passed to Paddle as line items and synced back after payment, keeping both records consistent.</li>
<li>Automatic order totals sync — After payment, the plugin synchronises WooCommerce order totals — including line-item subtotals, discounts, fees, tax lines, and the grand total — with the values reported by Paddle. An order note is added documenting the sync for auditing purposes.</li>
<li>Transaction & invoice ID tracking — The Paddle transaction ID and invoice ID are saved directly to the WooCommerce order and visible on the order detail screen.</li>
<li>Transaction URL — A direct link to the Paddle transaction is saved with each order so you can jump straight to the Paddle dashboard from WooCommerce.</li>
<li>Refund support — Initiate full or partial refunds from the standard WooCommerce refund interface; the plugin forwards the refund to Paddle automatically.</li>
<li>Invoice button on order screen — A one-click button on the admin single-order page lets you open or download the Paddle-generated invoice without leaving WooCommerce.</li>
<li>Order-pay page support — Customers can retry a failed or pending payment from the WooCommerce order-pay page; billing details are pre-populated automatically.</li>
<li>Light and dark themes — Choose between Paddle’s light and dark checkout UI to match your store’s design.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>PHP 8.1 or higher</li>
<li>WordPress 6.0 or higher</li>
<li>WooCommerce (latest recommended)</li>
<li>A <a href="https://paddle.com" rel="nofollow ugc">Paddle account</a> with an API key and client-side token</li>
</ul>

<ul>
<li>Production: <code>https://cdn.paddle.com/paddle/v2/paddle.js</code></li>
<li>Sandbox: same URL (environment is set via the client-side token)</li>
</ul>
This script is provided by Paddle.com Inc. and is required to open the hosted checkout modal.

<li><a href="https://www.paddle.com/legal/privacy" rel="nofollow ugc">Paddle Privacy Policy</a></li>
</ul>
<h4>Paddle REST API</h4>
The plugin communicates with the Paddle REST API from your server to create transactions and retrieve order details:
<ul>
<li>Production: <code>https://api.paddle.com</code></li>
<li>Sandbox: <code>https://sandbox-api.paddle.com</code></li>
</ul>
Data sent includes order line items, customer billing information (email, country, postcode), and currency. No data is sent unless a customer initiates checkout.
