PayPal Checkout for WS Form lets you accept PayPal or credit card payments from your forms in WordPress. You can charge a fixed amount with the button on its own, or use WS Form e-commerce fields for more advanced cart options.
The PayPal Checkout button uses PayPal’s latest client-side payment process. When a transaction is completed, WS Form stores the transaction ID with the form submission.
You can configure billing and shipping address mapping, pre-populate payer details, and map transaction breakdown values such as subtotal, shipping, tax, handling fee, shipping discount, insurance, and gift wrap. The payment page must be served over HTTPS.
