3DS authentication with Passthrough

Leveraging Passthrough

If you have your own 3DS Authentication service, you can integrate it seamlessly with PayU using Passthrough. This approach lets you manage the authentication process directly with your chosen Merchant Plug-in (MPI) or 3DS Server.

How Passthrough works

• Utilize your existing 3DS service: PayU integrates seamlessly with your preferred provider for a smooth workflow.
• Handle authentication: You manage the communication between your platform and the 3DS service.
• Send response to PayU: Include the authentication response from your 3DS service within your payment request to PayU.

Important considerations

• Independent services: Your 3DS service operates independently of PayU’s authorization service.
• Combined Data Required: For successful payment processing, your PayU authorization request must include the authentication response from your 3DS service.
