Change the connection protocol

By default, the connection between a POS and Clover device is over WebSocket Secure (WSS). The Clover Device Server also supports an unecrypted WebSocket (WS) connection. To change the connection type, complete the following steps.

🚧

IMPORTANT

A non-secure WS connection should only be used if needed for development and testing. WSS connections must be enabled in production.

  1. Tap the Server is Secured check box.
  2. Tap 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://.

WebSocket (WS) settings

Change the server port

By default, the connection between a POS and Clover device uses port 12345. The port can be modified by doing the following.

  1. Tap Server Port.
  2. On the Enter Server Port Number window, type a new port number.
  3. Tap Save.
  4. Tap Configure and Restart Server. The port change is applied.

📘

NOTE

If the new port is used by another process on the Clover device, an Address already in use message appears. To correct this issue, repeat the previous steps using a different port number.

Ping settings

To change the device's ping settings, modify one or more of the following values.

SettingDescription
Enable PingWhen checked, the device checks that the connection is open at the specified interval
Ping IntervalThe length of time between pings (in milliseconds)
Ping Retry Before DisconnectThe number of times the server will attempt to ping the client before disconnecting

Change the length of auth token validity

The number of days a pairing code is valid can be set for your environment. Once the interval elapses, a new code must be entered.

  1. Tap Auth tokens valid for.
  2. On the Enter # of Days window, change the number and then tap Save.
  3. Tap Configure and Restart Server. The validity interval is changed.

Device pairing screen

Enable the pairing screen

You can choose to display a screen which provides three ways to pair the device: a QR code, the device's DNS name, and the device's IP address.

  1. Tap the Enable pairing screen check box.
  2. Tap Configure and Restart Server.

Use the pairing screen

If the pairing screen is enabled, the Initiate Pairing button appears on the Network Pay Display screen. Tap Initiate Pairing to show the pairing screen.

Device server certificates

To establish trust between the 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 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 (US, EU, and Latin America):

Certificate URLs for US production

  1. https://www.clover.com/v2/env_device_ca_certificate
  2. https://www.clover.com/v2/env_device_ca_certificate.der
  3. https://www.clover.com/v2/env_device_ca_certificate.crt

Certificate URLs for EU production

  2. https://www.eu.clover.com/v2/env_device_ca_certificate.der
  3. https://www.eu.clover.com/v2/env_device_ca_certificate.crt

Certificate URLs for Latin America production

  2. https://www.la.clover.com/v2/env_device_ca_certificate.der
  3. https://www.la.clover.com/v2/env_device_ca_certificate.crt

Change the device certificate for development

By default, the device server certificate is issued by the Clover Prod Terminal Server Root CA. When you are working in the sandbox environment, change your CA using the following steps:

  1. In the SNPD app settings, select the Enable Development Certificate option.
  2. Select Configure and Restart Server. Once the server is restarted, the CA is updated.
  3. Select View Certificate Details and verify that the device certificate is issued by the Clover Device Server Root CA.
