Adyen’s Terminal API integration allows you to integrate your Point-of-Sale systems to our payment terminal.
The Adyen Terminal API is based on the nexo Retail Protocol. nexo uses JSON messages to communicate to and from the terminal. Messages are in JSON format and are formed as outlined in the nexo standard. Review our guidelines on how to form and validate these messages.
We offer two types of architecture to integrate your POS with our terminals:
- Local communication to the terminal - Directly with the terminal over the local network.
- Cloud-based communication to the terminal - Through our Terminal Gateway Platform at www.adyen.com.
This setup gives you the flexibility to start accepting payments as soon as possible.
After you've reviewed our guidelines on the Terminal API architecture and message structure, you're ready to begin integrating. To get started with your integration, see Make a Payment.
