This comprehensive guide walks you through migrating your Android application from the standalone Xen BRI SDK (version 0.3.1) to the new Terminal H2H SDK (version 0.4.0) and Terminal API (H2H) (version 0.4.1). The new architecture provides better integration with the Xendit In-Person Payment platform and supports multiple terminal providers.
This migration involves significant architectural changes. We recommend testing thoroughly in your development environment before deploying to production.

​
Overview of Changes

The new architecture separates the concerns of direct terminal communication (handled by the Terminal H2H SDK) and payment session management (handled by the Terminal API (H2H)). This provides a more unified approach for different terminal providers and better integration with the Xendit In-Person Payment platform. Key Changes:
  • SDK Consolidation: The XenBriTerminal SDK is replaced by the Terminal H2H SDK, which acts as a common interface for various terminal providers (e.g., TerminalBRI).
  • API for Payment Sessions: Instead of direct saleIntent calls from the SDK, payment sessions are now managed via the Terminal API (H2H).
  • Simplified Connection Management: Device registration and connection state observation are now handled more uniformly through TerminalH2H.
  • Unified Error Handling: Error codes are standardized across the Terminal H2H SDK.

​
Migration Steps

1

Update SDK Dependencies

Remove the old Xen BRI SDK dependency and add the new Terminal H2H SDK dependencies in your module’s build.gradle file.Old Dependency (to remove):
implementation("co.xendit:xen_edc_sdk-android:0.3.0")
New Dependencies (to add):
implementation("co.xendit.terminal:h2h-android:<latest_version>")
implementation("co.xendit.terminal:core-android:<latest_version>")
implementation("co.xendit.terminal:id-bri-android:<latest_version>") // For BRI terminals
// If you support NTT, also add:
// implementation("co.xendit.terminal:th-ntt-android:<latest_version>")
Also, ensure your project’s build.gradle or settings.gradle has the maven local repository:
repositories {
  ...
  maven("./repository") // in the project's settings.gradle, or
  // maven("../repository") // in project's build.gradle
  ...
}
2

Initialize the SDK

The initialization process changes from XenBriTerminal.initialize() to TerminalApp.initialize() and TerminalH2H.addProvider().Old Initialization:
override fun onCreate() {
    super.onCreate()
    XenBriTerminal.initialize(this, TEST_CLIENT_KEY,
        XenTerminalMode.INTEGRATION)
    // ...
}
New Initialization:
override fun onCreate() {
    super.onCreate()
      TerminalApp.initialize(this, TEST_CLIENT_KEY,
        TerminalMode.INTEGRATION) // Use TerminalMode from new SDK
      TerminalH2H.addProvider(TerminalBRI) // Add the BRI provider
      // If you support NTT, also add:
      // TerminalH2H.addProvider(TerminalNTT)
    // ...
}
Client Key: Note that for the Terminal API (H2H), you will need an API_KEY from the Xendit In-Person Payment team, which is different from the CLIENT_KEY used in the SDK initialization. The TerminalApp.initialize still uses a CLIENT_KEY.
TerminalMode: The XenTerminalMode enum is replaced by TerminalMode. Use TerminalMode.INTEGRATION for testing with physical terminals and TerminalMode.LIVE for production. TerminalMode.SIMULATION is no longer available directly in the TerminalApp.initialize method; instead, you would create payment sessions with appropriate simulation parameters via the Terminal API (H2H) if needed.
3

Register Terminal Devices

Instead of XenBriTerminal.useWifi() or XenBriTerminal.useBluetooth(), you now register devices using TerminalH2H.registerDevices().Old Device Connection (Example for WiFi):
XenBriTerminal.useWifi(TID, "127.0.0.1")
New Device Registration:
// Replace with your TID (Terminal ID) and IP address.
val devices = listOf(
    TerminalDevice(id = Terminal_ID_1, ipAddress = Terminal_IP_1, active = true),
    TerminalDevice(id = Terminal_ID_2, ipAddress = Terminal_IP_2, active = true),
    TerminalDevice(id = Terminal_ID_3, ipAddress = Terminal_IP_3, active = true)
)

TerminalH2H.registerDevices(
    devices = devices,
    restart = true // restart to apply the refreshed list immediately
)
Registration errors (such as authentication failures) are emitted through observeError. For obtaining TID and IP address for BRI terminals, continue using the BRI FMS App for TID and the ECRLink app for IP address.
4

Create Payment Transactions

The saleIntent method is replaced by a two-step process:
  1. Create a Payment Session via Terminal API (H2H): Your backend (or a direct API call from your app if applicable) initiates a payment session with the Xendit’s Payment Terminal API (H2H).
  2. The SDK will then handle the interaction with the physical terminal to process the payment based on the created session.
Old Payment Creation:
val payment = PaymentIntentParametersBuilder(
    transactionId = "123456",
    amount = 1000,
    method = SaleMethod.PURCHASE // Or other SaleMethod enums
).build()
XenBriTerminal.saleIntent(payment = payment) { result, error ->
    // handle result & error
}
New Payment Creation (High-Level Flow):
  1. Your Application/Backend (using Terminal API (H2H)):
    • Make a POST request to /v1/terminal/sessions to create a payment session.
    • Endpoint: https://terminal-dev.xendit.co (Development) or https://terminal.xendit.co (Live)
    • Headers:
      • Content-Type: application/json
      • Authorization: Basic <Base64Encode(API_KEY:)>
      • Idempotency-key: A unique key for preventing duplicate requests.
    • Request Body Example:
{
  "reference_id": "your-transaction-ref-123",
  "session_type": "PAY",
  "country": "ID",
  "currency": "IDR",
  "amount": 10000,
  "mode": "TERMINAL",
  "channel_properties": {
    "terminal_id": "YOUR_TERMINAL_ID",
    "order_id": "your-order-id-abc", // Required for IDR
    "payment_methods": ["ID_INSERT_CARD"] // Or other valid methods
  },
  "description": "Payment for goods",
  "metadata": {
    "key": "value"
  }
}
  • The API will return a payment_session_id. The Terminal H2H SDK on the terminal device, observing the commands from the API, will then initiate the payment process on the physical terminal.
  1. Terminal H2H SDK (Observing Connection and Error States):
    The Terminal H2H SDK will automatically process the payment command received from the API for the registered terminal. Your app can observe the connection and error states to react to the payment flow.
5

Handle Optional Methods

The Terminal H2H SDK provides new methods for these operations, often correlating with the Terminal API (H2H)‘s “Push Operation Command” functionality.

​
Reprint Receipt

Old:
XenBriTerminal.printReceiptIntent(result = result) { result, error ->
    // handle result & error
}
// or by using trace number
XenBriTerminal.printReceiptIntent(method = SaleMethod.PURCHASE, traceNumber = "A001") { result, error ->
    // handle result & error
}
New (using Terminal API (H2H)‘s Push Operation Command - only supported for Indonesia’s BRI terminals):Your application/backend would make a POST request to /v1/terminal/commands.
{
  "terminal_id": "YOUR_TERMINAL_ID",
  "command": "PRINT_RECEIPT",
  "payment_id": "OPTIONAL_PAYMENT_ID_TO_REPRINT_SPECIFIC_RECEIPT"
  // For reprint last, payment_id might be omitted based on API spec
}
The Terminal H2H SDK would then receive this command and execute the print operation.

​
Settlement

Old:
XenBriTerminal.settlementIntent(method = SaleMethod.PURCHASE) { result, error ->
    // handle result & error
}
New (using Terminal API (H2H)‘s Push Operation Command - only supported for Indonesia’s BRI terminals):Your application/backend would make a POST request to /v1/terminal/commands.
{
  "terminal_id": "YOUR_TERMINAL_ID",
  "command": "SETTLE"
}

​
Cancel Payment (Void Transaction)

Old:
XenBriTerminal.cancelPaymentIntent(result = result) { result, error ->
    // handle result & error
}
// or by using trace number
XenBriTerminal.cancelPaymentIntent(method = SaleMethod.PURCHASE, traceNumber = "A001") { result, error ->
    // handle result & error
}
New (using Terminal API (H2H)‘s Void a Payment):Your application/backend would make a POST request to /v1/terminal/payments/:payment_id/void.Path: /v1/terminal/payments/:payment_id/void
Method: POST
Headers:
  • Content-Type: application/json
  • Authorization: Basic <Base64Encode(API_KEY:)>
The payment_id would be obtained from the response of the “Create Payment Session” or “Get Payment Session Detail” API calls.

Observe Connection and Error States

The methods for observing connection and error states have been updated in the Terminal H2H SDK.

​
Observing Connection State

Old:
XenBriTerminal.observeConnection(CoroutineScope(Dispatchers.IO)) { state ->
   // handle state event
}
// or, using flow
val flow = XenBriTerminal.connectionState
New:
TerminalH2H.observeConnection(
  CoroutineScope(Dispatchers.IO),
  terminalDevice // Pass the specific TerminalDevice instance
) { state ->
   // handle state event
}
// Or with Flow,
val flow = terminalDevice.connectionState
The connection states (CONNECTED, DISCONNECTED, UNKNOWN, CONNECTING, CONNECTING_FAILED, UNSUPPORTED, UNREACHABLE) are similar but are now part of TerminalH2H and tied to a specific TerminalDevice.

​
Observing Error State

Old: Error handling was integrated into the saleIntent callback.New: A dedicated observeError method is available.
TerminalH2H.observeError(
  CoroutineScope(Dispatchers.IO)
) { device, error ->
   // handle state event
}
// Or with Flow,
val flow = TerminalH2H.errorState(terminalDevice)
// or
val flow = terminalDevice.error
The Error Data Structure and Error Codes have been standardized and are detailed in the Terminal H2H SDK for Android (Kotlin) documentation. Review these to update your error handling logic accordingly.

Troubleshooting and Kiosk Mode

The troubleshooting section regarding “Unresponsive EDC Machine” and “No Response from SDK on EDC payment completion” remains relevant and similar in concept.For Kiosk mode, the recommendation to enable “POS only mode” by providing Terminal IDs to the Xendit EDC team remains valid. This ensures transactions are initiated via the SDK/API and not directly on the terminal.
