The Payment widget is an integrated tool that allows you to offer multiple payment methods to end customers.

The Payment widget supports:

Alternative payment methods (APMs): Such as OXXO, KueskiPay, Aplazo, among others.
Credit and debit cards: Such as MasterCard, Visa, American Express, among others.

Initialize the widget

Before integrating the Payment widget, complete the Getting Started - Android.

1. Display the widget

Display the widget within your application using one of two options:

Display the widget in a DialogFragment dialog
Display the widget embedded in Jetpack Compose

Display the widget in a dialog

To display the Payment Widget in a DialogFragment, call the initPaymentWidget function passing the following data:

let deunaSDK: DeunaSDK = ....

deunaSDK.initPaymentWidget(
  context = YOUR_ACTIVITY_CONTEXT,
  orderToken = "<DEUNA order token>",
  userToken = "<DEUNA user token>", // Optional
  styleFile: "<DEUNA theme ID to customize the look and feel of the widget>", // Optional
  callbacks = PaymentWidgetCallbacks().apply {
    onSuccess = { data ->
      deunaSDK.close() // Close the DialogFragment of the payment widget
      // Your additional code
    }
    onCardBinDetected = { metadata, refetchOrder ->
      if (metadata != null) {
        // Your code here
      }
    }
    onInstallmentSelected = { metadata, refetchOrder ->
      // Your code here
    }
    onError = { error ->
      // Error handling
      when (error.type) {
        PaymentsError.Type.PAYMENT_ERROR -> {
          // YOUR CODE HERE
        }
        else -> {}
      }
    }
    onClosed = { action ->
      // Widget closed
    }
  },
)

Display the widget embedded (Jetpack Compose)

To display the payment widget embedded in your application with Compose, use the AndroidView composable and the DeunaWidget view.

📘
DeunaWidget does not support dynamic dimensions so the AndroidView container must define the dimensions that the DEUNA widget will use.

@Composable
fun YourScreen(
    deunaSDK: DeunaSDK,
    orderToken: String,
    userToken: String,
) {
    // Maintains the Deuna WebView instance across recompositions
    val deunaWidget = remember { mutableStateOf<DeunaWidget?>(null) }

    Column(modifier = Modifier.padding(16.dp)) {
        // Container for the embedded payment widget
        // MUST specify dimensions (e.g., .height(400.dp) or .weight(1f) in parent Column)
        Box(
            modifier = yourModifier
        ) {
            AndroidView(
                modifier = Modifier.fillMaxSize(),
                factory = { context ->
                    DeunaWidget(context).apply {
                        this.widgetConfiguration = PaymentWidgetConfiguration(
                            sdkInstance = deunaSDK,
                            hidePayButton = true, // (Optional) Hide the pay button in the embedded widget
                            orderToken = orderToken,
                            userToken = userToken,
                            callbacks = PaymentWidgetCallbacks().apply {
                                onEventDispatch = { event, data ->
                                    // Handle event dispatch
                                }
                                onSuccess = { data ->
                                    // Handle success
                                }
                                onError = { error ->
                                    // Handle error
                                }
                            },
                        )

                        this.build() // Render the DEUNA widget
                        // Store reference for later submission
                        deunaWidget.value = this
                    }
                }
            )
        }

        Spacer(modifier = Modifier.height(16.dp))

        // Custom payment submission button
        // Only needed when hidePayButton = true
        Button(
            onClick = {
                // Programmatically submit payment details to DEUNA
                // Required when hidePayButton = true
                deunaWidget.value?.submit { result ->
                    // Handle submission result
                    // result.status: "success"|"error"
                    // result.message: Detailed status message
                }
            },
            modifier = Modifier.fillMaxWidth()
        ) {
            Text("Complete Payment")
        }
    }

    // Critical: Clean up DeunaWidget resources when composable leaves composition
    DisposableEffect(Unit) {
        onDispose {
            deunaWidget.value?.destroy()
            Log.d("DeunaWidget", "WebView resources cleaned up")
        }
    }
}

DeunaWidget Auto-Resize Integration Guide (Android))

By default, DeunaWidget fills its parent container with a fixed height. When you configure an AutoResizeConfig, the widget switches to auto-resize mode: it grows and shrinks dynamically to match the height of its content. This is ideal for embedding the widget inside a scrollable container (ScrollView or a Jetpack Compose Column with vertical scroll) alongside other elements in your interface.

In auto-resize mode, the DeunaWidget automatically manages and detects the soft keyboard. It calculates the position of the active input field and triggers the exact scroll amount required to prevent the keyboard from covering the input the user is interacting with.

Requirements in AndroidManifest.xml

To ensure the system correctly resizes your layouts when the soft keyboard appears, your checkout Activity must be configured with adjustResize:
```
<activity
    android:name=".CheckoutActivity"
    android:windowSoftInputMode="adjustResize" />
```
Jetpack Compose Integration
In Compose, simply place the DeunaWidget inside a scrollable container (such as a Column with vertical scroll) and bind the SDK's scroll request to your Compose scroll state within the update block:

PaymentWidgetConfiguration(
    orderToken = "...",
    autoResizeConfig = AutoResizeConfig(initialHeightDp = 100),
    callbacks = PaymentWidgetCallbacks().apply { ... },
    sdkInstance = deunaSDK
)
.
.
.


@Composable
fun MyCheckoutScreen(widgetConfig: DeunaWidgetConfiguration) {
    val scrollState = rememberScrollState()
    val coroutineScope = rememberCoroutineScope()
    Column(
        modifier = Modifier
            .fillMaxSize()
            .verticalScroll(scrollState) // Main scrollable container
    ) {
        // ... Your content above the widget ...
        AndroidView(
            modifier = Modifier.fillMaxWidth(),
            factory = { context ->
                DeunaWidget(context).apply {
                    widgetConfiguration = widgetConfig
                    build()
                }
            },
            update = { widget ->
                // 🔥 Wire the SDK's scroll request to the Compose ScrollState
                widget.setOnScrollByCallback { amountPx ->
                    coroutineScope.launch {
                        scrollState.animateScrollBy(amountPx)
                    }
                }
            }
        )
        // ... Your content below the widget ...
    }
}

Parameters

Depending on how you display the payment widget, you should use one of the following options:

Dialog: Through calling the initPaymentWidget function.
Embedded: Through an instance of the PaymentWidgetConfiguration class.

Attributes	Dialog	Embedded	Description
`context`	✅	❌	The context is the context of your Activity in Android. It provides access to application-specific resources and information about the environment in which the application is running.
`orderToken`	✅	✅	The orderToken is a unique token generated for the payment order. This token is generated through DEUNA's API and you must implement the corresponding endpoint in your backend to obtain this information. When creating the order with DEUNA's API, a redirect URL (redirect_url) should not be defined so that the onSuccess callback runs correctly.
`callbacks`	✅	✅	Callbacks are return functions that are responsible for listening to and handling payment widget events. These events allow managing specific actions based on the payment status. The main callbacks include: `onSuccess`, `onError`, `onClosed`, `onCanceled`, `onCardBinDetected`, `onInstallmentSelected` If DEUNA's widget is displayed embedded, the callbacks must be passed within an instance of the `PaymentWidgetBridge` class, as shown in the Compose example code.
`userToken` (optional)	✅	✅	The DEUNA user's bearer token. When this is sent, all actions within the widget will be performed on this DEUNA user. For this userToken to be used and saved cards to be shown to the customer, the email associated with that userToken must be the same as the one sent when creating the order in `billing_address.email`. If both emails don't match, then the flow without showing cards is used for security.
`styleFile` (optional)	✅	✅	UUID provided by DEUNA. This applies if you want to configure a custom `custom styles` file (change colors, texts, logo, and so on). If a valid value is provided for `styleFile` the Payment widget will use the UI configuration provided by the theme configuration that matches the provided UUID.
`paymentMethods` (optional)	✅	✅	A list of allowed payment methods. This parameter determines what type of widget should be rendered.
`language`(optional)	✅	✅	This parameter allows you to specify the language in which the widget interface will be displayed. It must be provided as a valid language code (for example, "es" for Spanish, "en" for English, "pt" for Portuguese). Behavior: If provided: The widget uses the language specified in this parameter, regardless of the merchant's configuration. If not provided: The widget uses the language configured by the merchant.
`behavior` (optional)	✅	✅	Use this parameter to configure the widget's behavior.
`fraudCredentials` (optional)	✅	✅	This allows DEUNA to generate the fraudId and then send it to your anti-fraud provider. Check here for more info on how to configure this attribute
`domain` (optional)	✅	✅	This optional parameter is used to override the base host when the payment widget URL is loaded. It replaces the default host (pay.deuna.io) with the domain you provide. Example: If you pass the domain `https://myhost.com` The default URL: `https://pay.deuna.io/now/{ORDER_TOKEN}` Will become: `https://myhost.com/now/{ORDER_TOKEN}`

`fraudCredentials` parameter (optional)

The initPaymentWidget function and the PaymentWidgetConfiguration class accept the fraudCredentials parameter .

Example:

deunaSDK.initPaymentWidget(
    orderToken = "TOKEN",
    // ... otros parámetros
    fraudCredentials = mapOf(
        "RISKIFIED" to mapOf(
            "storeDomain" to "deuna.com"
        )
    )
);

  PaymentWidgetConfiguration(
    sdkInstance = deunaSDK,
    orderToken = "TOKEN",
    ...
    fraudCredentials = mapOf(
        "RISKIFIED" to mapOf(
            "storeDomain" to "deuna.com"
        )
    )
  );

`behavior` parameter (optional)

The initPaymentWidget function and the PaymentWidgetConfiguration class accept the behavior parameter, which must be an instance of the WidgetBehavior class.

This allows you to customize the Payment widget's behavior, including:

Enable payments with multiple cards.
Among other configuration options.

These configurations apply to all payment methods enabled in the widget.

2. Configure payment methods

Payment methods behavior `paymentMethods`

The paymentMethods parameter within behavior allows configuring global behaviors for all payment methods enabled in the widget.

flowType (flow type)

Values (string): twoStep or singleStep

Current compatibility: Exclusive for PayPal.

Controls the display flow for specific payment methods that require showing information prior to the payment form.

  /// DIALOG
  deunaSDK.initPaymentWidget(
    orderToken = "TOKEN",
    ...
    behavior = WidgetBehavior(
      paymentMethods = mapOf(
        "flowType" to "twoStep"
      )
    )
  );

  /// EMBEDDED
  PaymentWidgetConfiguration(
    sdkInstance = deunaSDK,
    orderToken = "TOKEN",
    ...
    behavior =  WidgetBehavior(
      paymentMethods = mapOf(
        "flowType" to "twoStep"
      )
    )
  );

Split payments with multiple cards

The Split Payments feature allows customers to split the payment of a purchase between multiple credit/debit cards.

Requisites:

The option must be enabled in the merchant configuration.
Currently, only splitting between a maximum of two cards is supported.

/// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "TOKEN",
  ...
  behavior = WidgetBehavior(
    paymentMethods = mapOf(
      "creditCard" to mapOf(
      	"splitPayments" to mapOf(
          "maxCards" to 2  // Maximum number of cards allowed
        )
      )
    )
  )
);

/// EMBEDDED
PaymentWidgetConfiguration(
  sdkInstance = deunaSDK,
  orderToken = "TOKEN",
  ...
  behavior = WidgetBehavior(
    paymentMethods = mapOf(
      "creditCard" to mapOf(
      	"splitPayments" to mapOf(
          "maxCards" to 2
        )
      )
    )
  )
);

Auto purchase configuration for PayPal

The auto purchase (automatic purchase) feature for PayPal allows processing payments instantly when:

The customer has previously linked their PayPal account.
Has authorized quick payments in their account.

deunaSDK.initPaymentWidget(
    orderToken = "<DEUNA order token>",
    paymentMethods =
        listOf(
            mapOf(
                "paymentMethod" to "wallet",
                "processors" to listOf("paypal_wallet"),
                "configuration" to mapOf("express" to true)
            )
        )
)

Configuration Parameters

Parameter	Type	Default value	Description
express	Boolean	true	When `true`, processes payment automatically if the customer has PayPal linked. When `false`, allows selecting or confirming the account.

📘
The express configuration will only work if only the PayPal configuration is passed in the paymentMethods parameter.

Show or hide payment methods

The Payment widget can display various payment methods available for an order, without the merchant having to individually add each APM button in their frontend.

When invoking the initPaymentWidget function, the paymentMethods parameter defines the payment methods that the widget shows:

If only one method is passed in paymentMethods, then the widget automatically opens the payment method form without showing buttons for other APMs.

// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "<DEUNA order token>",
  userToken = ..., // optional
  styleFile = ..., // optional
  callbacks = ...,
  paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("payu_oxxo_cash")
    )
  )
)

// EMBEDDED
PaymentWidgetConfiguration(
  sdkInstance = deunaSDK,
   orderToken ="<DEUNA order token>",
   userToken = ..., // optional
   paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("payu_oxxo_cash")
    )
  )
)

// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "<DEUNA order token>",
  userToken = ..., // optional
  styleFile = ..., // optional
  callbacks = ...,
  paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("daviplata")
    )
  )
)

// EMBEDDED
PaymentWidgetConfiguration(
   sdkInstance = deunaSDK,
   orderToken ="<DEUNA order token>",
   userToken = ..., // optional
   paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("daviplata")
    )
  )
)

// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "<DEUNA order token>",
  userToken = ..., // optional
  styleFile = ..., // optional
  callbacks = ...,
  paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("nequi_push_voucher")
    )
  )
)

// EMBEDDED
PaymentWidgetConfiguration(
   sdkInstance = deunaSDK,
   orderToken ="<DEUNA order token>",
   userToken = ..., // optional
   paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("nequi_push_voucher")
    )
  )
)

If more than one payment method is specified in the paymentMethods parameter, then the widget only shows those enabled methods that must be configured at the merchant level.

📘
For credit card processing, there is no need to pass the processors's array. You can have multiple processors configured for the use of routing.

// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "<DEUNA order token>",
  userToken = ..., // optional
  styleFile = ..., // optional
  callbacks = ...,
  paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "credit_card"
    ),
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("payu_oxxo_cash")
    ),
     mapOf(
        "paymentMethod" to "bnpl",
        "processors" to listOf("kueski")
    )
  )
)

// EMBEDDED
PaymentWidgetConfiguration(
   sdkInstance = deunaSDK,
   orderToken ="<DEUNA order token>",
   userToken = ..., // optional
   paymentMethods = listOf(
    mapOf(
        "paymentMethod" to "credit_card"
    ),
    mapOf(
        "paymentMethod" to "voucher",
        "processors" to listOf("payu_oxxo_cash")
    ),
     mapOf(
        "paymentMethod" to "bnpl",
        "processors" to listOf("kueski")
    )
  )
)

If no method list is specified in paymentMethods and the include_payment_options parameter was not used when creating the order, then the widget shows all payment methods configured for the merchant.

// DIALOG
deunaSDK.initPaymentWidget(
  orderToken = "<DEUNA order token>",
  userToken = ..., // optional
  styleFile = ..., // optional
  callbacks = ...,
  paymentMethods = null
)

// EMBEDDED
PaymentWidgetConfiguration(
   sdkInstance = deunaSDK,
   orderToken ="<DEUNA order token>",
   userToken = ..., // optional
   callbacks = ...,
   paymentMethods = null
)

Payment method configuration priorities

The following table shows how the Payment widget decides which payment forms to display when the paymentMethods parameter is not passed.

Priority	Configuration Source	Description	Behavior in case of a single payment method
1	Payment methods passed when executing the `.initPaymentWidget` function or `PaymentWidgetConfiguration`	Payment methods are shown according to those passed when starting the widget, as long as they are activated and configured at the merchant level.	If only one payment method is passed, then the widget automatically opens the payment method form without showing buttons.
2	Order and `include_payment_options`	The order is checked to verify if `include_payment_options` has payment methods that are configured and activated at the merchant level. Unconfigured methods are not shown.	If only one payment method is passed, then the widget automatically opens the payment method form without showing buttons.
3	Methods configured at merchant level (API `/payment-methods`)	If no payment method is passed either in the `.initPaymentWidget` function or in `include_payment_options` when creating the order, then the methods configured at the merchant level are taken.	If only one payment method is passed, then the widget automatically opens the payment method form without showing buttons.

3. Listen to widget events

When a transaction is successful or fails, it's important to update your interface to notify users about the transaction result. You can do this by listening to the Payment widget events through callbacks.

The instance of the PaymentWidgetCallbacks class passed to the initPaymentWidget function or to the PaymentWidgetConfiguration class allows you to listen to widget events through callbacks.

Define the respective callbacks to update your app's interface.

Callbacks

Callback	Modal	Embedded	When is it triggered?
`onSuccess`	✅	✅	It's run when the payment is completed. This callback contains a parameter of type Map<String,Any> with the order information.
`onError`	✅	✅	It's run when an error occurs. This callback contains a parameter of type PaymentsError, which identifies the type of error produced. See an example of the callback response here.
`onClosed` (optional)		❌	It's run when the dialog containing the Payment widget is closed. This callback contains a parameter of type enum `CloseAction` with the following values: `userAction`: When the widget was manually closed by the user, pressing the close button (X) or the back button on Android without the operation being completed. `systemAction`: When the widget is closed due to the execution of the `close` function. NOTE: For embedded implementation the `onClosed` callback does not execute.
`onCardBinDetected` (Optional)	✅	✅	It's run when the Payment widget detects the BIN of an entered credit or debit card or when the user deletes the entered card number. This callback contains a parameter of type Map<String,Any> with the bin information and brand of the entered card. NOTE: The parameter of type `Map<String,Any>` is `null` when the user deletes the text entered in the card number field.
`onInstallmentSelected` (optional)	✅	✅	If the order can be deferred, this callback will execute when the user selects the months to defer. This callback contains a parameter of type Map<String,Any> with the information of the months to defer selected by the user. NOTE*: The parameter of type `Map<String,Any>` is `null` when the user selects current payment (without installments).
`onPaymentProcessing` (optional)	✅	✅	This callback will execute when the user presses the pay button and the payment is being processed. If there is any incorrect field in the payment form this event will not run.
`onEventDispatch` (Optional)	✅	✅	It's run on all events that the widget can produce. This callback contains a parameter of type `CheckoutEvent` and the data associated with that event

📘
Use the onError to identify if the widget could not be displayed or if an error occurred while processing the payment.

onError = { error ->
    when (error.type) {
       // The widget could not be loaded
       PaymentsError.Type.INITIALIZATION_FAILED -> {
          deunaSDK.close()
       }

       // The payment failed
       PaymentsError.Type.PAYMENT_ERROR -> {
           // YOUR CODE HERE
       }

      else -> {}
   }
}

4. Close the widget

By default, when the widget is displayed in a dialog through the initPaymentWidget function, the Payment widget only closes when the user presses the widget's close button or when they press the "back" button on Android.

To close the dialog when a payment is successful or when an error occurs, you must call the close function.

The following example code shows how to close the widget when a payment is successful:

deunaSDK.initPaymentWidget(
  context = YOUR_ACTIVITY_CONTEXT,
  orderToken = "<DEUNA order token>",
  userToken = "<DEUNA user token>", // optional
  callbacks = PaymentWidgetCallbacks().apply {
    onSuccess = { order -> 
      deunaSDK.close() // Close the payment widget
      // Your additional code
    }
  }
)

5. Free widget resources

If DEUNA's widget is displayed embedded, then it's important to free the widget's resources when it's no longer needed.

Example

val deunaWidget = remember { mutableStateOf<DeunaWidget?>(null) }
.
.
.
AndroidView(
    modifier = Modifier.fillMaxSize(),
    factory = { context ->
        DeunaWidget(context).apply {
          .
          .
          .
            // Store reference for later submission
            deunaWidget.value = this
        }
    }
)

DisposableEffect(Unit) {
    onDispose {
        deunaWidget.value?.destroy()
    }
}

Optional features

In addition to the mandatory steps to operate the widget, you have the following customization options.

Customize widget appearance

Use the setCustomStyle function to customize the widget appearance:

await DeunaSDK.setCustomStyle({...});

📘
For more information, refer to Style Customization.

Example

// DIALOG
deunaSDK.initPaymentWidget(
  context = YOUR_ACTIVITY_CONTEXT,
  orderToken = "<DEUNA order token>",
  userToken = "<DEUNA user token>", // optional
  callbacks = PaymentWidgetCallbacks().apply {
    onCardBinDetected = { cardBinMetadata ->
         this.deunaSDK.setCustomStyle(
             data = JSONObject(
                        """

Refresh Payment widget

The refetchOrder function updates the Payment widget and returns the updated order data.

This function is useful, for example, when the merchant offers promotions. A common case is a "20% promotion when paying with Mastercard".

In this scenario:
he merchant listens to the onCardBinDetected event to identify the card brand.
The merchant updates the order in DEUNA (being responsible for calculating

In this scenario, the merchant listens to the onCardBinDetected event to identify the card brand. Then, the merchant updates the order in DEUNA (being responsible for calculating the promotions) and, through this function, notifies the widget to update, since the order amount might have changed.

Below is an example of using the refetchOrder function.

// DIALOG
deunaSDK.initPaymentWidget(
  context = YOUR_ACTIVITY_CONTEXT,
  orderToken = "<DEUNA order token>",
  userToken = "<DEUNA user token>", // optional
  callbacks = PaymentWidgetCallbacks().apply {
    onCardBinDetected = { metadata ->
      val cardBrand = metadata["cardBrand"] as String?
      if (cardBrand != null && cardBrand == "Mastercard"){
        deunaSDK.refetchOrder { order ->
          print("ORDER: $order")
        }
      }
    }
   ...
  }
)
// EMBEDDED JETPACK COMPOSE
// Maintains the Deuna WebView instance across recompositions
val deunaWidget = remember { mutableStateOf<DeunaWidget?>(null) }
.
.
.
deunaWidget.value.refetchOrder { order ->
}

Hide the payment button (Embedded Widget)

When the payment widget is displayed in embedded mode, you can use the hidePayButton parameter to hide the payment button from the DeunaWidget.

// Maintains the Deuna WebView instance across recompositions
val deunaWidget = remember { mutableStateOf<DeunaWidget?>(null) }
.
.
.
DeunaWidget(context).apply {
   // Set true to handle payment submission manually via submit()
   // Set false to use Deuna's built-in payment button
   this.widgetConfiguration = PaymentWidgetConfiguration(
     .
     .
     .
     hidePayButton = true,
     .
     .
     .
   )
   .
   .
   .
 }
deunaWidget.value?.isValid { it ->  }
deunaWidget.value?.submit {result -> }

You can use the following functions to validate and execute the payment.

Method	Description	Response
`.isValid{...}`	Validates if the entered information is correct and if the payment can be processed.	`true` if the information is valid, `false` otherwise.
`.submit{...}`	Executes the payment process, equivalent to pressing the pay button. Performs the same internal validations.	`{ status: "success", message: "Payment processed successfully" }` or `{ status: "error", message: "The submit flow is not available" }`

Considerations

It is recommended to use isValid{} before calling submit{} to avoid errors in the payment process.
If the payment flow is not yet available, submit{} will always return an error with the message "The submit flow is not available"

Initialize the widget

1. Display the widget

Display the widget in a dialog

Display the widget embedded (Jetpack Compose)

`DeunaWidget` does not support dynamic dimensions so the `AndroidView` container must define the dimensions that the DEUNA widget will use.

DeunaWidget Auto-Resize Integration Guide (Android))

`fraudCredentials` parameter (optional)

`behavior` parameter (optional)

2. Configure payment methods

Payment methods behavior `paymentMethods`

Split payments with multiple cards

Auto purchase configuration for PayPal

The express configuration will only work if only the PayPal configuration is passed in the `paymentMethods` parameter.

Show or hide payment methods

For credit card processing, there is no need to pass the processors's array. You can have multiple processors configured for the use of routing.
