PayPal Checkout (REST) for Webasyst Shop-Script

The stock PayPal plugin for Webasyst still uses the legacy Payments Standard form and IPN. That means redirects, lost "return to merchant" clicks and orders stuck unpaid when IPN fails. PayPal Checkout (REST) replaces it with PayPal's current Orders v2 API.

What changes for your buyers

Customers pay without leaving your order page — PayPal, Pay Later and debit/credit cards through PayPal's Smart Buttons. The order is marked paid the moment the capture completes.

What changes for you

No IPN to configure. Your server builds the amount, and after capture it re-reads the PayPal order and checks the order id, currency and amount before marking anything paid — a tampered browser cannot underpay. Refund in full or in part from the Shop-Script order screen. A dashboard widget shows open disputes, balances and recent transactions.

What you get

  • PayPal Orders v2 REST API with client ID + secret
  • In-page Smart Buttons and card payments — no redirect
  • Server-side amount, currency and order checks before marking paid
  • Full and partial refunds from the Shop-Script backend
  • Hides itself for currencies PayPal cannot settle (e.g. INR)
  • Sandbox mode for testing
  • No IPN required
  • Dashboard widget: open disputes, balances, latest transactions
