Connect point of sale app to the Clover device

Connection Options

Use one of two methods to connect your point of sale (POS) app to the Clover device:

• Cloud connection uses Clover Cloud Server and the Cloud Pay Display App on the device to broker messages between your POS app and the device.
• Local connection uses an embedded server within the REST Pay Display App on the device to broker messages between your POS app and the device.

Cloud connection

Clover maintains a cloud service for establishing a web socket connection between your application and the Clover device.

This type of connection is simpler to configure but requires a consistent, fast connection to the internet within the merchant's facility for optimal performance.

See Configure a cloud connection for more information.

Local REST connection

Your POS can connect directly to the Clover device over a local area network (LAN). This connection:

• Uses the Clover Device Server app to connect with your POS using WebSocket Secure (WSS) via TLS.
• Requires your POS to trust the Clover certificate authority (CA) that has issued the Clover Device Server certificate.
