Configure, Run and Test the PayServer

First download the PayServer bundle for Windows:

Configure

Before running the PayServer you have to supply a configuration file, which tells the server how it should run and what devices it has connected. The file has to be named config.yaml and it has to be placed in the server folder (the same folder as the server Jar and the run script).

The configuration file is defined in YAML format and should have the following structure. This is a full sample configuration file with all currently available options annotated with comments.

server: - protocol: P3 # P3 protocol transport: WEBSOCKET # over WebSocket connection port: 8080 # port number - protocol: P3 # P3 protocol transport: FRAMED_TCP # over framed TCP connection port: 8081 # port number devices: # sample configuration for a mock device which can be used for testing - name: Mock Device # human readable device name identifier: mockDevice # unique identifier (will be generated randomly if omitted) type: MOCK # device type comlink: MOCK # connection type # sample configuration for a Miura reader connected via USB - name: USB Miura # human readable device name identifier: usbMiura # unique identifier (will be generated randomly if omitted) type: MIURA # device type comlink: USB # connection type port: COM3 # virtual port name keep_alive: true # the device will be kept connected between transactions (false by default) idle_text: ["custom text", "with multiple", "lines", " centered"] # custom text that appears when the reader is in idle state # sample configuration for a Verifone reader connected via USB - name: USB Verifone # human readable device name identifier: usbVerifone # unique identifier (will be generated randomly if omitted) type: VERIFONE # device type comlink: USB # connection type port: COM0 # virtual port name keep_alive: true # the device will be kept connected between transactions (false by default) # sample configuration for a Verifone reader connected on WiFi or Ethernet - name: Network Verifone # human readable device name identifier: networkVerifone # unique identifier (will be generated randomly if omitted) type: VERIFONE # device type comlink: WIFI # connection type remote: 192.168.254.58 # address or DNS name of the reader port: 16107 # port number of the reader information: # optional extra information location: 3rd Room # human readable name of the server location settings: locale: en # locale to be used independent from the system one # transactions: # enable_signature_actions: true # specifies if transaction process will send out signature actions 

The server can handle serving multiple protocols at the same time but for most use cases only one server configuration is needed. If you intend to use the .NET Pay Client, use P3 as server protocol and WEBSOCKET as transport option.

The location and name for a device are not required — they are returned in some responses from the server so that you can display them in your UI if you would like to.

In the PayServer Windows bundle we include a sample configuration file named config-example.yaml located in the server subfolder. This file is correctly configured to be used with the .NET Pay Client but make sure to review the device list before applying it.

Set optional settings.transactions.enable_signature_actions to true, if you want to capture the shopper’s signature digitally and not on the physical receipt. After enabling this option, the signature action messages will be sent out during transaction processing and you need to implement the accompanying signature capture logic in your POS.

Set optional devices[].keep_alive to true, if you want the PayServer to stay connected to that particular device after you execute a transaction on it. This will increase the transaction speed but also prevent the device from entering standby mode. Beware that the device will be connected until you disconnect from the PayServer or until you use another device for a transaction.

Set optional devices[].idle_text to any custom idle text that should be shown while the device is in keep-alive state (i.e. no transaction is done, but the connection to the device is kept alive). Provide max 4 lines with 20 characters each and prefix the text with spaces to center it.

Run

The PayServer is meant to run as a Windows Service in the background. In the PayServer bundle you’ll find a Install PayServer Service shortcut on the top level: Just double click it and it will install and run the PayServer as a Windows Service.

The PayServer will then automatically start up and shutdown with the PC, so that your merchants do not have worry about running the PayServer. The service is also monitored and automatically restarted in case there was an issue with the PayServer. In case there appears to be a problem with the PayServer and you want to restart it, you can do so using the Restart PayServer Service shortcut.

Keep in mind that you need to restart the service every time you change the configuration via the server/config.yamlfile.

To stop the PayServer and uninstall the service use the Remove PayServer Service shortcut.
