Usage

Setup

Initilize payment module:

Don't forget to add permissions to your manifest:

<uses-permission android:name="android.permission.INTERNET" />

init of PaymentSdk class

PaymentSdkBuilder().apply {
        setDebugMode(BuildConfig.DEBUG)
        setPublicKey(TestData.PUBLIC_STORE_KEY_3D)
        setCardNumberFieldVisibility(true)
        setCardCVCFieldVisibility(false)
        setCardDateFieldVisibility(true)
        setCardHolderFieldVisibility(true)
        setNFCScanVisibility(true)
        setEndpoint(YOUR_CHECKOUT_ENDPOINT)
    }.build()

in PaymentSdkBuilder you can find full list for of properties

Implement OnResultListener

class MainActivity : AppCompatActivity(), OnResultListener {

    //here you will receive payment token
    override fun onTokenReady(token: String) {
    }
    
    //here you will receive final status of payment and token of credit card
    override fun onPaymentFinished(beGatewayResponse: BeGatewayResponse, cardToken: String?) {
    }
}

BeGatewayResponse parameters:

    val status: ResponseStatus
    //SUCCESS("successful"),
    //ERROR("error"),
    //CANCELED("canceled"),
    //INCOMPLETE("incomplete"),
    //FAILED("failed"),
    //TIME_OUT("time_out");
    
    val message: String?     //details message about `ResponseStatus`

Start payment

You can receive payment token

            sdk.getPaymentToken(
                TokenCheckoutData(
                    Checkout(
                        test = BuildConfig.DEBUG,// true only if you work in test mode
                        transactionType = TransactionType.PAYMENT,
                        order = Order(
                            amount = 100,
                            currency = "USD",
                            description = "Payment description",
                            trackingId = "merchant_id",
                            additionalData = AdditionalData(
                                contract = arrayOf(
                                    Contract.RECURRING,
                                    Contract.CARD_ON_FILE
                                )
                            )
                        ),
                        settings = Settings(
                            returnUrl = "https://DEFAULT_RETURN_URL.com",
                            autoReturn = 0,
                        ),
                    ),
                ).apply {
                    addCustomField("customField", "custom string")
                }
            )

With this payment token you can do:

1. Start payment with card form

            startActivity(
                PaymentSdk.getCardFormIntent(this@MainActivity)
            )

2. Start payment with CheckoutWithTokenData

here you also can use payment token from your server or etc.

    private fun payWithCheckout() {
        sdk.checkoutWithTokenData = CheckoutWithTokenData(
            CheckoutWithToken(
                token = token
            )
        )
        startActivity(
            PaymentSdk.getCardFormIntent(this@MainActivity)
        )
    }

3. To make a payment using a saved card, you must initialize the SDK, receive a payment token, then turn on the "Saver card" switch when paying with the card. The card token will be saved, then you can call the UI of the saved cards using the function:

   private fun payWithCard() {
        val token = binding.tilToken.editText?.text?.toString() ?: return
        startActivity( PaymentSdk.getSaveCardIntent(this@MainActivity, token))
    }

Dynamic Fields

To any object of request you can add dynamic field by using methods that provide AdditionalFields class.

        Checkout(
            test = true,
            transactionType = TransactionType.PAYMENT,
            order = Order(
                amount = 100,
                currency = "USD",
                description = "Payment description",
                trackingId = "merchant_id",
                additionalData = AdditionalData(
                    contract = arrayOf(
                        Contract.RECURRING,
                        Contract.CARD_ON_FILE
                    )
                ).apply {
                    addCustomField("orderCustomBooleanKey", true)
                }
            ).apply {
                    addCustomJsonObject(JsonObject().apply {
                        add("toOrder", JsonArray().apply {
                            add("str")
                            add("str2")
                            add("str3")
                            add(true)
                        })
                    })
            },
            settings = Settings(
                returnUrl = "https://DEFAULT_RETURN_URL.com",
                autoReturn = 0,
            ).apply {
                addCustomField("settingsCustomIntKey", 14006)
            },
        ).apply {
            addCustomField("checkoutCustomStrKey", "checkoutCustomStrValue")
        }

You have access to our serializer CustomSerializer and AdditionalFields.

Encryption

Use PaymentSdk.encryptData(data: String) to get encrypted credit card data

For example:

val encryptedCardNumber = sdk.encryptData("4200000000000000")
val encryptedHolder = sdk.encryptData("IVAN IVANOV")
val encryptedCvv = sdk.encryptData("123")

Customizing

Customize using styles.xml

You can rewrite main style for card form view elements in your styles.xml

    <style name="begateway_Theme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
        <!-- Primary brand color. -->
        <item name="colorPrimary">@color/purple_200</item>
        <item name="colorPrimaryVariant">@color/purple_700</item>
        <item name="colorOnPrimary">@color/black</item>
        <!-- Secondary brand color. -->
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_200</item>
        <item name="colorOnSecondary">@color/black</item>
        <!-- Status bar color. -->
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <!-- Customize your theme here. -->
    </style>

Customize using string.xml

You can rewrite string for card form view elements in your string.xml, just put in your project string with same names but other values

<resources>
    <string name="begateway_form_hint_card_number">Card number</string>
    <string name="begateway_form_hint_expiration">Expiration date</string>
    <string name="begateway_form_hint_cardholder_name">Name on card</string>
</resources>

Customize using dimens.xml

You can rewrite dimens for text size of fields

<resources>
    <dimen name="begateway_card_number_text_size">16sp</dimen>
    <dimen name="begateway_card_holder_text_size">16sp</dimen>
    <dimen name="begateway_card_expire_date_text_size">16sp</dimen>
    <dimen name="begateway_card_cvc_text_size">16sp</dimen>
</resources>

Bank card scanning

NFC

if device has nfc sdk will show to user button for scanning

By Camera

you can choose any library that you want to use, just add to your manifest ScanBankCardActivity activity with our action

        <activity android:name=".ScanBankCardActivity">
            <intent-filter>
                <action android:name="com.begateway.mobilepayments.action.SCAN_BANK_CARD"/>
            </intent-filter>
        </activity>

and implement logic of library that you've chosen and when you will have a result send to our sdk

                setResult(
                      Activity.RESULT_OK,
                      PaymentSdk.getCardDataIntent(
                          scanResult.cardNumber,
                          scanResult.cardholderName,
                          scanResult.expiryMonth.toString(),//02
                          scanResult.expiryYear.toString(),//2021 or 21
                          scanResult.cvv                   // or you can use getCardDataIntentWithExpiryString() where expiryString can be 02/21 or 02/2021
                      )
                  )
                  finish()

Google Pay

if you want pay with google pay add this to your manifest

        <meta-data
            android:name="com.google.android.gms.wallet.api.enabled"
            android:value="true" />
