Opn Payments is a payment service provider currently operating in Thailand. Opn Payments provides a set of clean APIs that help merchants of any size accept cards online.
Opn Payments Android SDK provides Android bindings for the Opn Payments Token and Source API and components for entering credit card information.
It is imperative that you use at least the minimum recommended SDK version of 4.3.1 for security reasons. Any version below this poses severe risks of security vulnerabilities, bugs, and unexpected behaviors, which can be detrimental to your application. To avoid these risks and ensure the best user experience, it is highly recommended that you upgrade to the latest supported SDK version. Opn strongly advises the use of version 5.0.0 for superior performance and top-notch security.
- Public key. Register for an Opn Payments account to obtain your API keys.
- Android 5.0+ (API 21) target or higher.
- Android Studio and Gradle build system.
Card data should never transit through your server. We recommend that you follow our guide on how to safely collect credit information.
To be authorized to create tokens server-side, you must have a currently valid PCI-DSS Attestation of Compliance (AoC) delivered by a certified QSA Auditor.
This SDK provides the means to tokenize card data on an end-user mobile phone without the data having to go through your server.
Add the following line to your project's build.gradle file inside the dependencies
block:
implementation 'co.omise:omise-android:4.3.1'- UI Customization Overhaul: Introducing a new theme-based UI customization approach. Previously customized UI configurations must be updated. This offers configurations for
DefaultTheme,DarkTheme, andMonoChromeTheme. SeeCheckoutActivity.ktin the example app for a detailed implementation. - Charge Authorization: A new parameter named
EXTRA_THREE_DS_REQUESTOR_APP_URLhas been introduced and is required for charge authorization. Ensure this parameter is passed during the start ofAuthorizingPaymentActivityto prevent errors. - Automatic Initialization: The function
initializeAuthoringPaymentConfig()has been removed and is no longer needed. The SDK now handles initialization automatically. Removed functions:
val threeDSConfig = ThreeDSConfig.Builder()
.uiCustomization(uiCustomization)
.timeout(5)
.build()
val authPaymentConfig = AuthorizingPaymentConfig.Builder()
.threeDSConfig(threeDSConfig)
.build()
AuthorizingPaymentConfig.initialize(authPaymentConfig)The simplest way to use this SDK is to integrate the provided CreditCardActivity
directly into your application. This activity contains a pre-made credit form and will
automatically tokenize card
information for you.
To use it, first declare the availability of the activity in your AndroidManifest.xml
file as follows:
<activity
android:name="co.omise.android.ui.CreditCardActivity"
android:theme="@style/OmiseTheme" />Then, in your activity, declare the method that will start this activity. Launching the activity depends on which version of Android/AGP you are using. Here is a simple example using registerForActivityResult:
private val OMISE_PKEY: String = "pkey_test_123"
private val REQUEST_CC: Int = 100
private lateinit var creditCardLauncher: ActivityResultLauncher<Intent>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
creditCardLauncher = registerForActivityResult(
ActivityResultContracts.StartActivityForResult()
) { result: ActivityResult ->
handleActivityResult(
CREDIT_CARD_REQUEST_CODE,
result.resultCode,
result.data
)
}
}
private fun payByCreditCard() {
Intent(this, CreditCardActivity::class.java).run {
putExtra(OmiseActivity.EXTRA_PKEY, PUBLIC_KEY)
creditCardLauncher.launch(this)
}
}Replace the string pkey_test_123 with the public key obtained from your Opn Payments dashboard.
We discuss the handleActivityResult function in the following section.
After the end-user completes entering credit card information, the activity result callback will be called; handle it as follows:
private fun handleActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (resultCode == RESULT_CANCELED) {
snackbar.setText(R.string.payment_cancelled).show()
return
}
}Unless you are working on a project with specific backward compatibility requirements,
we recommend using registerForActivityResult to handle activity results in your Android apps.
You can then attach a function to handle the activity result inside the registerForActivityResult.
You do not need to set the requestCode explicitly in your handle function, but it is included here for simplicity.
You can have a specific function for each intent that you launch, and that function will handle the particular
result logic of that intent without the need for the request code.
Several results are returned from the activity. You can obtain them from the
resulting Intent with the following code:
data.getStringExtra(OmiseActivity.EXTRA_TOKEN)- The string ID of the token. Use this if you only need the ID and not the card data.data.getParcelableExtra(OmiseActivity.EXTRA_TOKEN_OBJECT)- The fullTokenobject returned from the Opn Payments API.data.getParcelableExtra(OmiseActivity.EXTRA_CARD_OBJECT)- TheCardobject that is part of theTokenobject returned from the Opn Payments API.
The getParcelableExtra(key) function is deprecated and no longer recommended to be used. We advise you to
create your custom function to retrieve the necessary information, as different Android versions may require you to
account for backward compatibility.
If you need to build your card form, components inside CreditCardActivity
can be used on their own. For example, the CreditCardEditText can be used in XML as demonstrated:
<co.omise.android.ui.CreditCardEditText
android:layout_width="match_parent"
android:layout_height="wrap_content" />This component provides automatic spacing into groups of 4 digits as the user inputs their card number. Additionally, the following utility classes are available from the SDK:
co.omise.android.ui.CreditCardEditText- TheCreditCardEditTextclass provides utility methods for validating and formatting credit card numbers.co.omise.android.ui.CardNameEditText- TheCardNameEditTextclass handles formatting and input type for card holder name.co.omise.android.ui.ExpiryDateEditText- TheExpiryDateEditTextclass handles formatting and date range limitation.co.omise.android.ui.SecurityCodeEditText- TheSecurityCodeEditTextclass handles formatting and input type for security code.
If you have built your card or Google Pay form, you can use the SDK to tokenize the
card manually. First, build the Client and supply your public key as follows:
private val client = Client("pkey_test_123")Then, construct the token request with values from your custom form:
// Sample builder for credit card
val cardParam = CardParam(
name = "JOHN Doe",
number = "4242424242424242",
expirationMonth = 10,
expirationYear = 2020,
securityCode = "123"
)
val request = Token.CreateTokenRequestBuilder(cardParam).build()
// Sample builder for Google Pay
val tokenizationParam = TokenizationParam(
method = "googlepay",
data = "{\"signature\":\"MEQCIA+wGZttxT13yz599zQjYugoz5kClNSmVa39vKv6ZOenAiARRtHQ0aYSrfd3oWhB\/ZtEeJs3ilT\/J0pYz1EWnzU2fw\\u003d\\u003d\",\"intermediateSigningKey\":{\"signedKey\":\"{\\\"keyValue\\\":\\\"MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEev+pVoUgtoS+y8Ecz3c72OFBD3d74XJOcnRxVmCV+2TJTW1g4d0UhDkhHeURhHQNvJPyBFHfYIUUj\/EYhYAzgQ\\\\u003d\\\\u003d\\\",\\\"keyExpiration\\\":\\\"1647856171825\\\"}\",\"signatures\":[\"MEYCIQClXfVcil7qaG2btVbyzf6x1\/MqCTbbJM\/tGN4iME4M9wIhANL53daWJHdDPpKxR3M\/Jis4WPVb093PW7fChj\/gCQUS\"]},\"protocolVersion\":\"ECv2\",\"signedMessage\":\"{\\\"encryptedMessage\\\":\\\"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\\\\u003d\\\\u003d\\\",\\\"ephemeralPublicKey\\\":\\\"BGJhfH3jWMmZtIALmYr7fWxYSNSCFoAT9MCOcbCZdO3LmP6njpGk9LISmr+H1Wk9XUZuMvNQmMHE+yFzW\/sA5lg\\\\u003d\\\",\\\"tag\\\":\\\"d9a6aVaoIEQm+bTjd5M2HL7+OeIup0Jb6rM1CN7v3NQ\\\\u003d\\\"}\"}",
// Add your billing information here (optional)
billing_name = "John Doe",
billing_street1 = "1600 Amphitheatre Parkway"
)
val request = Token.CreateTokenRequestBuilder(tokenization = tokenizationParam).build()Then send the request using the client that you have constructed earlier:
client.send(request, object : RequestListener<Token>{
override fun onRequestSucceed(model: Token) {
// you've got a Token!
}
override fun onRequestFailed(throwable: Throwable) {
// something bad happened
}
})The Client class will automatically dispatch the network call on an internal background
thread, and will call listener methods on the thread that initially calls the send
method.
Another way to use the Opn Payments Android SDK is to integrate the PaymentCreatorActivity
to allow users to create a payment source from the list of sources available for the account.
To use it, first declare the availability of the activity in your AndroidManifest.xml file as follows:
<activity
android:name="co.omise.android.ui.PaymentCreatorActivity"
android:theme="@style/OmiseTheme" />Then in your activity, declare the method that will start this activity as follows:
private val OMISE_PKEY: String = "pkey_test_123"
private val REQUEST_CC: Int = 100
private lateinit var paymentCreatorLauncher: ActivityResultLauncher<Intent>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
paymentCreatorLauncher = registerForActivityResult(
ActivityResultContracts.StartActivityForResult()
) { result: ActivityResult ->
handleActivityResult(
PAYMENT_CREATOR_REQUEST_CODE,
result.resultCode,
result.data
)
}
}
private fun showPaymentCreatorActivity() {
Intent(this, PaymentCreatorActivity::class.java).run {
putExtra(OmiseActivity.EXTRA_PKEY, PUBLIC_KEY)
putExtra(OmiseActivity.EXTRA_AMOUNT, 150000L)
putExtra(OmiseActivity.EXTRA_CURRENCY, "thb")
//You can retrieve your account's capabilities through the SDK (will be explained below)
putExtra(OmiseActivity.EXTRA_CAPABILITY, capability)
paymentCreatorLauncher.launch(this)
}
}Replace the string pkey_test_123 with the public key obtained from your Opn Payments dashboard.
Declare a capability variable as a Capability object and pass it as the value for the OmiseActivity.EXTRA_CAPABILITY key for your Intent. This way, the PaymentCreatorActivity will display the payment methods in the Capability object.
There are two options to retrieve the Capability object.
-
You can retrieve the Capability object from your account's capabilities through the Retrieve Capabilities function.
-
You can also create a
Capabilityobject to create your own capabilities using the helper functionCapability.create().Here is the sample:
val capability = Capability.create( allowCreditCard = true, sourceTypes = listOf(SourceType.PromptPay, SourceType.TrueMoney) )
Note Ensure you are adding payment methods supported by the account. If not, you won't be able to create a source to continue the payment process.
After the end user selects and creates a payment source, the activity result callback will be called; handle it as follows:
private fun handleActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (resultCode == RESULT_CANCELED) {
snackbar.setText(R.string.payment_cancelled).show()
return
}
when (requestCode) {
PAYMENT_CREATOR_REQUEST_CODE -> {
// if the payment method requires both source and token then you will receive both objects
// otherwise one object will be received
if(data.hasExtra(OmiseActivity.EXTRA_TOKEN) && data.hasExtra(OmiseActivity.EXTRA_SOURCE_OBJECT)){
val source = data.parcelable<Source>(OmiseActivity.EXTRA_SOURCE_OBJECT)
val token = data.parcelable<Token>(OmiseActivity.EXTRA_TOKEN_OBJECT)
snackbar.setText((source?.id ?: "No source object.") + "/" + (token?.id ?: "No token object.")).show()
Log.d(TAG, "source: ${source?.id}")
Log.d(TAG, "token: ${token?.id}")
} else if (data.hasExtra(OmiseActivity.EXTRA_SOURCE_OBJECT)) {
val source = data.parcelable<Source>(OmiseActivity.EXTRA_SOURCE_OBJECT)
snackbar.setText(source?.id ?: "No source object.").show()
Log.d(TAG, "source: ${source?.id}")
} else if (data.hasExtra(OmiseActivity.EXTRA_TOKEN)) {
val token = data.parcelable<Token>(OmiseActivity.EXTRA_TOKEN_OBJECT)
snackbar.setText(token?.id ?: "No token object.").show()
Log.d(TAG, "token: ${token?.id}")
}
}
}
}Two different results that could be returned are:
data.hasExtra(OmiseActivity.EXTRA_SOURCE_OBJECT)- TheSourceobject created by the payment creator.data.hasExtra(OmiseActivity.EXTRA_TOKEN)- TheTokenobject created in case the payment source created was a card.
We support GooglePay as a tokenization method in our payment gateway. This activity contains a pre-made Pay with Google Pay button and will automatically tokenize the Google Pay token for you.
To use it, first declare the availability of the activity in your AndroidManifest.xml
file as follows:
<activity
android:name="co.omise.android.ui.GooglePayActivity"
android:theme="@style/OmiseTheme" />Then in your activity, declare the method that will start this activity as follows:
private val OMISE_PKEY: String = "pkey_test_123"
private val amount: Long = 3000
private val currency: String = "THB"
private val cardBrands: ArrayList<String> = arrayListOf("Visa", "Mastercard")
private val googlepayMerchantId: String = "merchant_123"
private val googlepayRequestBillingAddress: Boolean = false
private val googlepayRequestPhoneNumber: Boolean = false
private val REQUEST_GPAY: Int = 100
override fun navigateToGooglePayForm() {
val intent = Intent(activity, GooglePayActivity::class.java).apply {
putExtra(EXTRA_PKEY, OMISE_PKEY)
putExtra(EXTRA_AMOUNT, amount)
putExtra(EXTRA_CURRENCY, currency)
putStringArrayListExtra(EXTRA_CARD_BRANDS, cardBrands)
putExtra(EXTRA_GOOGLEPAY_MERCHANT_ID, googlepayMerchantId)
putExtra(EXTRA_GOOGLEPAY_REQUEST_BILLING_ADDRESS, googlepayRequestBillingAddress)
putEXTRA(EXTRA_GOOGLEPAY_REQUEST_PHONE_NUMBER, googlepayRequestPhoneNumber)
}
gPayLauncher.launch(this)
}- Replace the
OMISE_PKEYwith your Opn Payments public key obtained from our dashboard. - Replace the
amountwith the amount you want to charge in subunits. - Replace the
currencywith your currency in the ISO 4217 format. - Replace the
cardBrandswith the list from our capability API or leave it blank to use default values. - Replace the
googlepayMerchantIdwith your Google Pay merchant ID (not needed in test mode). - Set the
googlepayRequestBillingAddresstotrueto attach the cardholder's name and billing address to the token. - When the cardholder's billing address is requested, set the
googlepayRequestPhoneNumbertotrueto also attach the cardholder's phone number to the token.
Several results are returned from the activity. You can obtain them from the
resulting Intent with the following code:
data.getStringExtra(OmiseActivity.EXTRA_TOKEN)- The string ID of the token. Use this if you only need the ID and not the card data.data.getParcelableExtra(OmiseActivity.EXTRA_TOKEN_OBJECT)- The fullTokenobject returned from the Opn Payments API.data.getParcelableExtra(OmiseActivity.EXTRA_CARD_OBJECT)- TheCardobject that is part of theTokenobject returned from the Opn Payments API.
You can use your activity if you prefer. We recommend that you follow Google's tutorial and guidelines and make sure that you follow their brand guidelines as well.
You can use our Google Pay request builder request/GooglePay.kt, which includes request builders that you can use to request the Google Pay token.
Configurations for the builders are modifiable through the class constructor to suit your needs. However, you are also welcome to make your own integration and call
our tokens builder yourself.
If you need to create a payment source and use it outside the provided SDK context, follow these steps. First, build the Client and supply your public key in this manner:
private val client = Client("pkey_test_123")Then, construct the Source request:
val request = Source.CreateSourceRequestBuilder(25000L, "thb", SourceType.Installment.Bay)
.description("Item")
.email("e@mail.com")
.storeId("id-123")
.storeName("Store")
.phoneNumber("06207658854")
.installmentTerm(3)
.build()Then, send the request using the Client you have constructed earlier. You will get a Source object in response:
client.send(request, object : RequestListener<Source>{
override fun onRequestSucceed(model: Source) {
// you've got a Source!
}
override fun onRequestFailed(throwable: Throwable) {
// something bad happened
}
})The Client class will automatically dispatch the network call on an internal background thread and call listener methods on the thread that initially calls the send method.
You can retrieve your capabilities and available payment sources through the SDK in the following manner.
First build the Client and supply your public key this way:
private val client = Client("pkey_test_123")Then, construct the Capability request:
val request = Capability.GetCapabilitiesRequestBuilder().build()And then send the request using the Client that you constructed earlier:
client.send(request, object : RequestListener<Capability> {
override fun onRequestSucceed(model: Capability) {
// you have capabilities!
}
override fun onRequestFailed(throwable: Throwable) {
// something bad happened
}
})The Client class will automatically dispatch the network call on an internal background thread and call listener methods on the thread that initially calls the send method.
If you wish to customize the elements on the CreditCardActivity to
match your application's branding, you can do so by overriding the following styles
as shown in the following snippet:
AndroidManifest.xml
<activity
android:name="co.omise.android.ui.CreditCardActivity"
android:theme="@style/SampleTheme" />style.xml
<resources>
<style name="SampleTheme" parent="Theme.MaterialComponents">
<item name="android:editTextStyle">@style/SampleEditText</item>
<item name="materialButtonStyle">@style/SampleButton</item>
<item name="editTextLabelStyle">@style/SampleEditTextLabel</item>
<item name="editTextErrorStyle">@style/SampleEditTextError</item>
</style>
<style name="SampleEditText" parent="Widget.AppCompat.EditText">
<item name="android:textColor">#FFFFFFFF</item>
<item name="android:textColorHint">#B3FFFFFF</item>
<item name="android:textSize">12sp</item>
<item name="backgroundTint">#FFFFFFFF</item>
</style>
<style name="SampleEditTextLabel">
<item name="android:textColor">#B3FFFFFF</item>
<item name="android:textAppearance">@style/TextAppearance.AppCompat.Body1</item>
</style>
<style name="SampleEditTextError">
<item name="android:textColor">#FFFF0000</item>
</style>
<style name="SampleButton" parent="Widget.MaterialComponents.Button">
<item name="backgroundTint">#FFFFFFFF</item>
<item name="android:textColor">#FF000000</item>
</style>
</resources>
And if you choose to customize the item text sizes for the lists in PaymentCreatorActivity, you
can do so by overriding the following style.
AndroidManifest.xml
<activity
android:name="co.omise.android.ui.PaymentCreatorActivity"
android:theme="@style/SampleTheme" />style.xml
<resources>
<style name="SampleTheme" parent="Theme.MaterialComponents">
...
<item name="android:itemTextAppearance">@style/SampleItemTextAppearance</item>
</style>
<style name="SampleItemTextAppearance" parent="TextAppearance.AppCompat.Body1">
<item name="android:textSize">16sp</item>
<item name="android:textColor">#FFFFFF</item>
</style>
</resources>Some payment methods require the customer to authorize the payment using an authorization URL. This includes 3-D Secure verification, Internet Banking payment, Mobile Banking SCB, etc. Opn Payments Android SDK provides a built-in class to handle the authorization.
On payment methods that require opening the external app (e.g., mobile banking app) to authorize the transaction, set the return_uri to a deep link or app link to be able to open the merchant app. Otherwise, after the cardholder authorizes the transaction on the external app, the flow redirects to the normal link in the return_uri, and opens it on the browser app, resulting in the payment not being completed. Some authorized URLs will be processed using the in-app browser flow, and others will be processed using the native flow from the SDK (3DS v2), and the SDK automatically handles all of this.
To use it, first declare the availability of the activity in your AndroidManifest.xml
file as follows:
<activity
android:name="co.omise.android.ui.AuthorizingPaymentActivity"
android:theme="@style/OmiseTheme" />Then in your activity, declare the method that will start this activity as follows:
private fun startAuthoringPaymentActivity() {
Intent(this, AuthorizingPaymentActivity::class.java).run {
putExtra(EXTRA_AUTHORIZED_URLSTRING, authorizeUrl)
putExtra(EXTRA_EXPECTED_RETURN_URLSTRING_PATTERNS, arrayOf(returnUrl))
putExtra(EXTRA_UI_CUSTOMIZATION, uiCustomization)
putExtra(
EXTRA_THREE_DS_REQUESTOR_APP_URL,
"sampleapp://omise.co/authorize_return"
)
authorizingPaymentLauncher.launch(this)
}
}Replace the string EXTRA_AUTHORIZED_URLSTRING with the authorized URL that comes with the created charge and the array of string EXTRA_EXPECTED_RETURN_URLSTRING_PATTERNS with the expected pattern of redirected URLs array.
Replace the string EXTRA_THREE_DS_REQUESTOR_APP_URL with the url of your app to allow the external bank apps to navigate back to your app when required.
The EXTRA_UI_CUSTOMIZATION parameter is used to customize the UI of the built-in 3DS SDK during the 3DS challenge flow.
If you want to customize the title of the authorizing payment activity, you must use the theme customization and pass the headerText in the toolbarCustomization in the DEFAULT theme parameter:
val toolbarCustomization = ToolbarCustomizationBuilder()
.textFontName("font/roboto_mono_bold.ttf")
.textColor("#000000")
.textFontSize(20)
.backgroundColor("#FFFFFF")
.headerText("Secure Checkout")
.buttonText("Close")
.build()
val uiCustomization = UiCustomizationBuilder()
.setDefaultTheme(ThemeConfig(
toolbarCustomization = toolbarCustomization,
))
.build()You can check out the UiCustomization class to see customizable UI elements in the challenge flow.
After the end-user completes the payment authorization process, the activity result callback will be sent, and you will receive different responses based on how the transaction was processed and which flow it used. Handle it in this manner:
fun handleActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
// custom result code when web view is closed
if (resultCode == AuthorizingPaymentActivity.WEBVIEW_CLOSED_RESULT_CODE) {
snackbar.setText(R.string.webview_closed).show()
return
}
if (resultCode == RESULT_CANCELED) {
snackbar.setText(R.string.payment_cancelled).show()
return
}
if (data == null) {
snackbar.setText(R.string.payment_success_but_no_result).show()
return
}
when (requestCode) {
AUTHORIZING_PAYMENT_REQUEST_CODE -> {
with(data.parcelable<AuthorizingPaymentResult>(AuthorizingPaymentActivity.EXTRA_AUTHORIZING_PAYMENT_RESULT)) {
Log.d(TAG, this.toString())
val resultMessage = when (this) {
is AuthorizingPaymentResult.ThreeDS1Completed -> "Authorization with 3D Secure version 1 completed: returnedUrl=${returnedUrl}"
is AuthorizingPaymentResult.ThreeDS2Completed -> "Authorization with 3D Secure version 2 completed: transStatus=${transStatus}"
is AuthorizingPaymentResult.Failure -> {
Log.e(TAG, throwable.message, throwable.cause)
throwable.message ?: "Unknown error."
}
null -> "Authorization result not found"
}
Log.d(TAG, resultMessage)
snackbar.setText(resultMessage).show()
}
}
}
}You can check out the sample implementation in the CheckoutActivity class in the sample app.
The following utility function observes the token until its charge status changes. You can use it to check the charge status after the payment authorization process is completed.
val client = Client("pkey_test_1234")
client.observeTokenUntilChargeStatusChanged("tokn_test_1234", object: RequestListener<Token> {
override fun onRequestSucceed(model: Token) {
TODO("Not yet implemented")
}
override fun onRequestFailed(throwable: Throwable) {
TODO("Not yet implemented")
}
})Some request methods allow the user to authorize the payment with an external app, for example Alipay. When a user needs to authorize the payment with an external app, AuthorizingPaymentActivity will automatically open an external app. However, merchant developers must handle the Intent callback themselves.
If you enable ProGuard, then add these rules to your ProGuard file.
