Fusion Satellite

The Fusion Satellite API allows a Sale System running on the POI terminal to communicate with the DataMesh Satellite payment application on the same POI terminal using inter-app communication with Android intents.

Libraries

DataMesh have published a library to Maven Central which wraps the Satellite API. This is the recommended method of interacting with the Fusion Satellite API.

Description	Location
Library	on Maven Central
Library	on GitHub
Demo Application utilising the library	on GitHub	Tested on PAX (PAX 920)
Another POS on Pinpad Demo Application	on GitHub	Tested on PAX (PAX 920) and Ingenico (DX8000)

How to include the library

implementation "com.datameshgroup.fusion:fusion-sdk:1.3.4"

If you are using Android you will need to add Java 8 syntax desugaring. In your app's build.gradle

android {
	compileOptions {
		sourceCompatibility JavaVersion.VERSION_1_8
		targetCompatibility JavaVersion.VERSION_1_8
		coreLibraryDesugaringEnabled true
	}
}
dependencies {
	coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.1.5'
}

Device Specific Changes

If your Sale System on Pinpad uses the device(s) listed below, the following changes need to be included in your application:

Printer

If your Sale System on Pinpad only supports PAX:

• Modify the App Manifest file to add the following permission:
  <uses-permission android:name="com.pax.permission.PRINTER" />

If your Sale System on Pinpad supports Ingenico or

If your Sale System on Pinpad supports both Ingenico and PAX:

Since not all the required changes specific to your application may be listed below, please refer to the POS on Pinpad Demo Application code in GitHub. This POS on Pinpad Demo Application code in GitHub has been tested in both Ingenico (DX8000) and PAX (PAX 920)

Please only copy the code/files relevant to the device(s) that you support.(e.g. copy only the relevant Ingenico code/file(s) if you only support Ingenico)

• Add the relevant Library Files
• Add the relevant device specific files:
  • Ingenico
  • PAX
• Add the DeviceInterface.java file and its references to your code.
• Update your app's build.gradle

    flavorDimensions 'device'
    productFlavors {
        pax {
            dimension "device"
            applicationId = "you_application_id_here"
            buildConfigField 'boolean', 'DEVICE_PAX', 'true'
            buildConfigField 'boolean', 'DEVICE_IGO', 'false'
            buildConfigField 'String', 'VERSION_TYPE', "\"v1\""

        }
        ingenico {
            dimension "device"
            applicationId = "you_application_id_here"
            buildConfigField 'boolean', 'DEVICE_PAX', 'false'
            buildConfigField 'boolean', 'DEVICE_IGO', 'true'
            buildConfigField 'String', 'VERSION_TYPE', "\"v1\""
        }
    }

Sending messages

The Satellite API utilises an Android intent with request/response objects based on the Nexo SaleToPOIRequest and SaleToPOIResponse

Sample code for Sending a Payment Request

Please refer to the method in the file listed below to view sample code handling on how to perform a payment/refund.

Method Name	GitHub File	GitHub Repository
sendPaymentRequest	ActivityPayment.java	pos-on-pinpad-demo

Intent request

The app uses intents to send and receive messages

Intent intent = new Intent(Message.INTENT_ACTION_SALETOPOI_REQUEST);

// All messages to and from the terminal are wrapped inside a Message object.
// Here request is a SaleToPOIRequest object.
Message message = new Message(request);

intent.putExtra(Message.INTENT_EXTRA_MESSAGE, message.toJson());
// name of this app, that get's treated as the POS label by the terminal.
intent.putExtra(Message.INTENT_EXTRA_APPLICATION_NAME, "DemoPOS");
intent.putExtra(Message.INTENT_EXTRA_APPLICATION_VERSION, "1.0.0");

// we are using 100 as the request code - but you can use anything you want.
startActivityForResult(intent, 100);

Intent response

In the same activity, add the following code.

@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data){
    super.onActivityResult(requestCode, responseCode, data);
    if(data != null && data.hasExtra(Message.INTENT_EXTRA_MESSAGE)) {
        this.handleResponseIntent(data);
    }
}

void handleResponseIntent(Intent intent){
    // The response is sent as a Json and we will need to deserialize it.
    Message message = null;
    try{
        message = Message.fromJson(intent.getStringExtra(Message.INTENT_EXTRA_MESSAGE));
    } catch(Exception e){
        // json errors may occur,
        // if this is occuring, make sure you are using the latest fusion-sdk library
        return;
    }
    SaleToPOIResponse response = message.response;
    // we can now access the data.
}

Request/response object

SaleToPOIRequest

{
  "SaleToPOIRequest": {
    "MessageHeader":{...},
    "PaymentRequest":{...}
  }
}

SaleToPOIResponse

{
  "SaleToPOIResponse": {
    "MessageHeader":{...},
    "LoginRequest":{...}
  }
}

All messages use JSON format with UTF-8 encoding.

Supported primitive data elements are:

1. String text string of variable length
2. Boolean true or false
3. Number defined in this document as either integer or decimal. For all number fields the Sale System MUST remove the digits equal to zero on left and the right of the value and any useless decimal point (eg. 00320.00 is expressed 320, and 56.10 is expressed 56.1). This simplifies parsing and MAC calculations.
4. Null optional types can be represented as null

tip

Additional fields will be added to the message specification over time. To ensure forwards compatibility the Sale System must ignore when extra objects and fields are present in response messages.

The base of every message is the SaleToPOIRequest object for requests, and SaleToPOIResponse object for responses.

The SaleToPOIRequest and SaleToPOIResponse contain two objects:

1. A MessageHeader object.
2. A Payload object of variable types.

MessageHeader

MessageHeader

"MessageHeader":{
  "MessageClass":"",
  "MessageCategory":"",
  "MessageType":"",
  "ServiceID":""
}

A MessageHeader is included with each request and response. It defines the protocol and message type.

Attributes	Requ.	Format	Description
MessageClass	✔	String	Informs the receiver of the class of message. Possible values are "Service", "Device", or "Event"
MessageCategory	✔	String	Indicates the category of message. Possible values are "CardAcquisition", "Display", "Login", "Logout", "Payment"
MessageType	✔	String	Type of message. Possible values are "Request", "Response", or "Notification"
ServiceID	✔	String	A unique value which will be mirrored in the response. See ServiceID.

Payload

An object which defines fields for the request/response. The object name depends on the MessageCategory defined in the MessageHeader

e.g. a payment will include a PaymentRequest/PaymentResponse.

The Satellite API Reference outlines the expected payload for each supported request.

Methods

Payment

The payment message is used to perform purchase, purchase + cash out, cash out only, refund, pre-authorisation, and completion requests.

Void/Reversal

A successful payment transaction can be voided/reversed by sending a reversal request message.

warning

There are only specific cases wherein the reversal request message must be sent. In most cases, refund request message should be sent instead.

Please discuss first with the DataMesh Integrations team at integrations@datameshgroup.com if you plan to implement any void/reversal processing.

When the Sale System receives the successful payment response, the Sale System needs to store the TransactionID (Response.POIData.POITransactionID.TransactionID) since this will be used in the reversal request message.

Reversal request

The reversal message is used to perform void/reversal request.
