Clover SDK for Javascript Integration

Current version: 1.2.0

Overview

This SDK provides an API to allow your application using Javascript to interface with a Clover® Mini device (https://www.clover.com/pos-hardware/mini)

The API is available on GitHub for download, and can be used:

• in conjunction with the proper browser framework from a NodeJS require directive, hosted on NPM
• in conjunction with a server based NodeJS application by including a compatible WebSocket and XMLHttpRequest library.

1. The remotepay/ICloverConnector is the high-level API with methods like Sale(), VoidTransaction(), ManualRefund(), etc.
2. The remotepay/ICloverConnectorListener is the high-level listener API that defines callback methods like onSaleResponse, onRefundPaymentResponse, etc.
3. The API includes objects that map to standard Clover objects such as Payment, CardTransaction, Order, etc. These objects will match those defined in clover-android-sdk

If used from a browser, the library requires the browser you use to support WebSockets. See WebSocket Browser Support.

var $ = require('jQuery');

var clover = require("remote-pay-cloud");
var log = clover.Logger.create();

var connector = new clover.CloverConnectorFactory().createICloverConnector({
    "oauthToken": "1e7a9007-141a-293d-f41d-f603f0842139",
    "merchantId": "BBFF8NBCXEMDV",
    "clientId": "3RPTN642FHXTX",
    "remoteApplicationId": "com.yourname.yourapplication:1.0.0-beta1",
    "deviceSerialId": "C031UQ52340015",
    "domain": "https://sandbox.dev.clover.com/"
});

var ExampleCloverConnectorListener = function(cloverConnector) {
    clover.remotepay.ICloverConnectorListener.call(this);
    this.cloverConnector = cloverConnector;
};

ExampleCloverConnectorListener.prototype = Object.create(clover.remotepay.ICloverConnectorListener.prototype);
ExampleCloverConnectorListener.prototype.constructor = ExampleCloverConnectorListener;

ExampleCloverConnectorListener.prototype.onReady = function (merchantInfo) {
    var saleRequest = new clover.remotepay.SaleRequest();
    saleRequest.setExternalId(clover.CloverID.getNewId());
    saleRequest.setAmount(10000);
    this.cloverConnector.sale(saleRequest);
};

ExampleCloverConnectorListener.prototype.onVerifySignatureRequest = function (request) {
    log.info(request);
    this.cloverConnector.acceptSignature(request);
};

ExampleCloverConnectorListener.prototype.onConfirmPaymentRequest = function (request) {
  this.cloverConnector.acceptPayment(request.payment);
};

ExampleCloverConnectorListener.prototype.onSaleResponse = function (response) {
    log.info(response);
    connector.dispose();
    if(!response.getIsSale()) {
        console.error("Response is not an sale!");
        console.error(response);
    }
};

var connectorListener = new ExampleCloverConnectorListener(connector);
connector.addCloverConnectorListener(connectorListener);
connector.initializeConnection();

// Close the connection cleanly on exit.  This should be done with all connectors.
$(window).on('beforeunload ', function () {
    try {
        connector.dispose();
    } catch (e) {
        console.log(e);
    }
});

Breakdown

Import the libraries needed to create the clover object.

var clover = require("remote-pay-cloud");

Create the Clover Connector object.

This will require gathering the configuration information to create the connector. In this example, the configuration is hard coded. The creation of the connector is done using the connector factory.

var connector = new clover.CloverConnectorFactory().createICloverConnector({
    "merchantId": "BBFF8NBCXEMDT",
    "clientId": "3RPTN642FHXTC",
    "remoteApplicationId": "com.yourname.yourapplication:1.0.0-beta1",
    "deviceSerialId": "C031UQ52340045",
    "domain": "https://sandbox.dev.clover.com/"
});

There are several ways the Clover Connector object can be configured.

Examples of configurations that can be used when creating the Clover Connector object:

1. With a clientID, domain, merchantId, deviceSerialId

{
  "clientId" : "3BZPZ6A6FQ8ZM",
  "remoteApplicationId": "com.yourname.yourapplication:1.0.0-beta1",
  "domain" : "https://sandbox.dev.clover.com/",
  "merchantId" : "VKYQ0RVGMYHRS",
  "deviceSerialId" : "C021UQ52341078"
}

1. With a oauthToken, domain, merchantId, clientId, deviceSerialId

{
  "oauthToken" : "6e6313e8-fe33-8662-7ff2-3a6690e0ff14",
  "domain" : "https://sandbox.dev.clover.com/",
  "merchantId" : "VKYQ0RVGMYHRS",
  "clientId" : "3BZPZ6A6FQ8ZM",
  "remoteApplicationId": "com.yourname.yourapplication:1.0.0-beta1",
  "deviceSerialId" : "C021UQ52341078"
}

Define a listener that will listen for events produced byt the Clover Connector.

The functions implemented will be called as the connector encounters the events. These functions can be found in the clover.remotepay.ICloverConnectorListener.

// This overrides/implements the constructor function.  This example
// expects that a clover connector implementation instance is passed to the created listener.
var ExampleCloverConnectorListener = function(cloverConnector) {
    clover.remotepay.ICloverConnectorListener.call(this);
    this.cloverConnector = cloverConnector;
};
ExampleCloverConnectorListener.prototype = Object.create(clover.remotepay.ICloverConnectorListener.prototype);
ExampleCloverConnectorListener.prototype.constructor = ExampleCloverConnectorListener;

// The ICloverConnectorListener function that is called when the device is ready to be used.
// This example starts up a sale for $100
ExampleCloverConnectorListener.prototype.onReady: function (merchantInfo) {
    var saleRequest = new clover.remotepay.SaleRequest();
    saleRequest.setExternalId(clover.CloverID.getNewId());
    saleRequest.setAmount(10000);
    this.cloverConnector.sale(saleRequest);
};

// The ICloverConnectorListener function that is called when the device needs to have a signature
// accepted, or rejected.
// This example accepts the signature, sight unseen
ExampleCloverConnectorListener.prototype.onVerifySignatureRequest = function (request) {
    log.info(request);
    this.cloverConnector.acceptSignature(request);
};

// The ICloverConnectorListener function that is called when the device detects a possible duplicate transaction,
// due to the same card being used in a short period of time. This example accepts the duplicate payment challenge, sight unseen
ExampleCloverConnectorListener.prototype.onConfirmPaymentRequest = function (request) {
  this.cloverConnector.acceptPayment(request.payment);
};

// The ICloverConnectorListener function that is called when a sale request is completed.
// This example logs the response, and disposes of the connector.  If the response is not an expected
// type, it will log an error.
ExampleCloverConnectorListener.prototype.onSaleResponse = function (response) {
    log.info(response);
    connector.dispose();
    if(!response.getIsSale()) {
        console.error("Response is not an sale!");
        console.error(response);
    }
};

Add the listener instance to the connector, and initialize the connection to the device.

var connectorListener = new ExampleCloverConnectorListener(connector);
connector.addCloverConnectorListener(connectorListener);
connector.initializeConnection();

Clean up the connection on exit of the window. This should be done with all connectors.

This example uses jQuery to add a hook for the window beforeunload event that ensures that the connector is displosed of.

$(window).on('beforeunload ', function () {
    try {
        connector.dispose();
    } catch (e) {
        console.log(e);
    }
});

        }
        let saleRequest:Clover.remotepay.SaleRequest = new Clover.remotepay.SaleRequest();
        saleRequest.setExternalId(Clover.CloverID.getNewId());
        saleRequest.setAmount(10);
        console.log({message: "Sending sale", request: saleRequest});
        this.cloverConnector.sale(saleRequest);

    }
    public onSaleResponse(response:Clover.remotepay.SaleResponse): void {
        try{
            console.log({message: "Sale response received", response: response});
            if (!response.getIsSale()) {
                console.error("Response is not a sale!");
            }
            console.log("Test Completed.  Cleaning up.");
            this.cloverConnector.showWelcomeScreen();
            this.cloverConnector.dispose();
        } catch (e) {
            console.error(e);

Breakdown

Import the libraries needed to create the clover object.

import * as Clover from 'remote-pay-cloud';

Create the Clover Device Configuration object.

Depending on the mode of configuration, you may choose to use a WebSocketPairedCloverDeviceConfiguration, or a WebSocketCloudCloverDeviceConfiguration.

export class StandAloneExampleWebsocketPairedCloverDeviceConfiguration extends 
                 Clover.WebSocketPairedCloverDeviceConfiguration {
...
}

There are many ways the Clover Connector object can be configured. This includes a direct connection with a browser as shown here, connecting using a browser via the cloud similar to the above example, and connecting using a NodeJS application.

Define a listener that will listen for events produced byt the Clover Connector.

The functions implemented will be called as the connector encounters the events. These functions can be found in the clover.remotepay.ICloverConnectorListener.

export class StandAloneExampleCloverConnectorListener extends Clover.remotepay.ICloverConnectorListener {
...
}

Create the Clover Connector Factory object.

The factory can be obtained using the builder. If unspecified, the factory will produce 1.1.0 compatible connectors. Here we specify the 1.2 version.

let configuration = {};
configuration[Clover.CloverConnectorFactoryBuilder.FACTORY_VERSION] = 
      Clover.CloverConnectorFactoryBuilder.VERSION_12;
let connectorFactory: Clover.ICloverConnectorFactory = 
      Clover.CloverConnectorFactoryBuilder.createICloverConnectorFactory(configuration);

Create the Clover Connector object.

Using the configuration object you created, call the factory function to get an instance of a Clover Connector.

let cloverConnector: Clover.remotepay.ICloverConnector =
    connectorFactory.createICloverConnector(
      new StandAloneExampleWebsocketPairedCloverDeviceConfiguration());

Add the listener instance to the connector, and initialize the connection to the device.

cloverConnector.addCloverConnectorListener(new StandAloneExampleCloverConnectorListener(cloverConnector));
cloverConnector.initializeConnection();

Clean up the connection on exit of the window. This should be done with all connectors.

This example uses jQuery to add a hook for the window beforeunload event that ensures that the connector is displosed of.

$(window).on('beforeunload ', function () {
    try {
        connector.dispose();
    } catch (e) {
        console.log(e);
    }
});
