Clover Device Server settings page

From here you can:

Select the connection protocol

By default, the connection between a point of sale (POS) and Clover device is over WebSocket Secure (WSS). The Clover Device Server also supports an unencrypted WebSocket (WS) connection. A non-secure WS connection should only be used if needed for development and testing. WSS connections must be enabled in production.

To change the connection type:

  1. Access Clover device server settings.
  2. Select the Server is Secured check box.Click Configure and Restart Server.
    The lock icon changes from green to red. On the Network Pay Display screen, the device URLs change from wss:// to ws://.

Work with device server certificates

To establish trust between the point of sale (POS) and the device server certificate issued by the Clover CA, you must install a Clover Device Server Root CA certificate on the POS. Clover provides separate certificates for development and production use.

🚧

IMPORTANT

The certificate must be installed in the Trusted Root Certification Authorities store. If the certificate is not installed in the correct store, a certificate chain error message appears when you attempt to connect.

Sandbox (development)

The device server certificate is issued by the Clover Device Server Root CA. The CA certificate is hosted at:

Certificate URLs (links) for development:

  1. https://sandbox.dev.clover.com/v2/device_ca_certificate
  2. https://sandbox.dev.clover.com/v2/device_ca_certificate.der
  3. https://sandbox.dev.clover.com/v2/device_ca_certificate.crt

Production

The device server certificate is issued by the Clover Prod Terminal Server Root CA. The CA certificate is hosted at different locations for each region—United States (US), Europe, and Latin America (LATAM):

  1. Access Clover device server settings.
  2. Select the Enable Development Certificate checkbox.
  3. Select Configure and Restart Server. Once the server is restarted, the CA is updated.
