Use Case Identification

To show you the most relevant upgrade options, we need to understand which PayPal integration you're currently using.

Not sure which integration you have? Look for these clues:
  • Express Checkout – You're currently using NVP/SOAP API to process payments
  • Website Payments Standard – Button-based integration that redirects customers to PayPal
  • SDK Upgrade – You're currently using older checkout.js or JS SDK v5
Select your current integration to see your upgrade options. Need more help identifying your integration?
