WPInterface Checkout with Paddle for Easy Digital Downloads

Paddle is a merchant of record: it sells your products on your behalf and takes care of payments, sales tax and VAT, invoices and compliance in every country. This plugin connects Paddle to Easy Digital Downloads (EDD) 3.x, so buyers pay in a Paddle popup on your own checkout page and EDD delivers the files and licence keys.

Works with both Paddle accounts

• Paddle Billing (accounts created after August 2023): API key and client-side token.
• Paddle Classic (older accounts): Vendor ID, API Auth Code and public key.

Checkout

• Paddle’s secure checkout opens as an overlay on your checkout page. Buyers never leave your site.
• Cards, PayPal, Apple Pay and Google Pay, as enabled in your Paddle account.
• No product setup in Paddle: every order is sent with its own prices, so EDD discount codes, fees, variable prices and multi-item carts just work.
• Light or dark theme, checkout language (automatic or fixed), optional payment icons, your own payment method label.
• Works with the EDD checkout shortcode and the EDD checkout block.
• A Paddle-hosted fallback for buyers without JavaScript.

Reliable and safe

• Every webhook is signature-verified; nothing else can mark an order paid.
• One click sets up the webhook in Paddle Billing and stores its secret.
• Duplicate and simultaneous webhooks are handled, so an order is never completed or refunded twice.
• Several stores can share one Paddle account; each store only acts on its own orders.
• Payments are confirmed directly with Paddle when the buyer returns (Billing), so a slow webhook doesn’t leave anyone waiting.
• Underpaid, wrong-currency or outdated-checkout payments are flagged instead of completing the order.
• Test connection button, clear admin warnings and a debug log.
