Interswitch payment SDK allows you to accept payments from customers within your mobile application. The first step to using the Android SDK is to register as a merchant. This is described [here] (http://merchantxuat.interswitchng.com/paymentgateway/getting-started/overview/sign-up-as-a-merchant)
Download the latest SDK from the link below
https://github.com/techquest/isw-payment-sdk-android/releases
It consists of 5 libraries:
- core.jar
- payment.jar
- payment-android-release.aar
- gson-2.3.1.jar
- deviceprint-release-2.2.0.aar
Use Android Studio’s dependency management tool (Gradle) to add the libraries to your project.
- Download Android Studio 1.2.2 or later
- Create a new project
- Add core.jar, payment.jar, payment-android-release.aar, deviceprint-release-2.2.0.aar and gson-2.3.1.jar to your project by putting them in the libs folder of the app.
- To add the payment-android-release.aar library, navigate to File -> New -> New Module -> Import .JAR/.AAR Package option in Android Studio.
- Select the payment-android-release.aar
- Repeat step 4 to step 5 to add deviceprint-release-2.2.0.aar to your project. Then select deviceprint-release-2.2.0.aar where apllicable.
- Finally, rebuild the project
Ask the user for card details
In the onClick method of the button that asks the user to pay, add this code Please note, supply your client id and client secret you got after registering as a merchant
//Setup client id and secret
RequestOptions options = RequestOptions.builder()
.setClientId("IKIA3E267D5C80A52167A581BBA04980CA64E7B2E70E")
.setClientSecret("SagfgnYsmvAdmFuR24sKzMg7HWPmeh67phDNIiZxpIY=").build(); //Setup request parameters
final PurchaseRequest request = new PurchaseRequest();
//Optional email, mobile no, BVN etc to uniquely identify the customer
request.setCustomerId(“1234567890");
request.setAmount(“100"); //Amount in Naira
request.setCurrency("NGN");
request.setPan(“5060100000000000012"); //Card No
request.setPinData("1111"); //Card PIN
request.setExpiryDate("2004"); // expiry date in YYMM format
request.setTransactionRef(RandomString.numeric(12)); //unique transaction reference
Context context = this; // reference to your Android Activity //Send payment
new PaymentSDK(context, options).purchase(request, new IswCallback<PurchaseResponse>() {
@Override
public void onError(Exception error) {
// Handle and notify user of error
}
@Override
public void onSuccess(PurchaseResponse response) {
if (StringUtils.hasText(response.getOtpTransactionIdentifier())) {
//OTP required
//Ask user for OTP and authorize transaction using the otpTransactionIdentifier
}
else {
//OTP not required
//Handle and notify user of successful transaction
}
}
});
First set your client id and client secret
//Setup client id and secret
RequestOptions options = RequestOptions.builder()
.setClientId("IKIA3E267D5C80A52167A581BBA04980CA64E7B2E70E")
.setClientSecret("SagfgnYsmvAdmFuR24sKzMg7HWPmeh67phDNIiZxpIY=").build();To load Verve wallet, add this code, use the resulting payment methods array to populate a spinner
//Load Wallet
final WalletRequest request = new WalletRequest();
request.setTransactionRef(RandomString.numeric(12));
Context context = this; // reference to your Android Activity
new WalletSDK(context, options).getPaymentMethods(request, new IswCallback<WalletResponse>() {
@Override
public void onError(Exception error) {
// Handle and notify user of error
}
@Override
public void onSuccess(WalletResponse response) {
PaymentMethod[] paymentMethods = response.getPaymentMethods();
//Display payment methods in a Spinner
}
});
After populating the spinner, when the user selects an item and then clicks pay, use this code
//Setup request parameters using wallet item
final PurchaseRequest request = new PurchaseRequest();
//Optional email, mobile no, BVN etc to uniquely identify the customer
request.setCustomerId(“1234567890");
//Amount in Naira
request.setAmount("100");
request.setCurrency("NGN");
if (paymethodSpinner.getSelectedItem() == null) {
return;
}
request.setPan(((PaymentMethod) paymethodSpinner.getSelectedItem()).getToken());
request.setPinData(pin.getText().toString());
request.setTransactionRef(RandomString.numeric(12)); //Send payment
new WalletSDK(context, options).purchase(request, new IswCallback<PurchaseResponse>() {
@Override
public void onError(Exception error) {
// Handle and notify user of error
}
@Override
public void onSuccess(PurchaseResponse response) {
if (StringUtils.hasText(response.getOtpTransactionIdentifier())) {
//OTP required
//Ask user for OTP and authorize transaction using the otp Transaction Identifier
} else { //OTP not required
//Handle and notify user of successful transaction
}
}
##Checking status of payment
To check the status of a payment made, use the code below
//pass the transaction ref and the amount as the parameters to getPaymentStatus()
new WalletSDK(context, options).getPaymentStatus("117499114589", "100", new IswCallback<PaymentStatusResponse>() {
@Override
public void onError(Exception error) {
// Handle and notify user of error
}
@Override
public void onSuccess(PaymentStatusResponse response) {
//print response message
}
