Who should use this guide

This guide is intended for merchants who:

• Use Payrails as a payment orchestrator
• Use Adyen Payments
• Are approved to process raw card data

We use a server-to-server integration with Adyen, so your account must be enabled to process raw card data. If this isn’t enabled, payments won’t work in production. Please contact your Adyen account manager or support team to activate it.

How to request access to raw card data processing

1. Email [email protected] and copy [email protected].
2. Optionally copy the Payrails Support team.
3. In your request, confirm that Payrails will act as the payment orchestrator and handle card data processing.
4. Include:
   • The WS user associated with your Adyen account
   • The Payrails PCI compliance document
