Ready-to-Use UI

1. Create AmazonPay Config

Create AmazonPay configuration object.

OPPAmazonPayConfig *amazonPayConfig = [[OPPAmazonPayConfig alloc] initWithRegion:OPPAmazonPayRegionUS];

let amazonPayConfig = OPPAmazonPayConfig(region: .US)

2. Create CheckoutSettings

Create CheckoutSettings and set brand configuration.

OPPCheckoutSettings *checkoutSettings = [[OPPCheckoutSettings alloc] init];
        
// Set Amazon Pay payment methods
checkoutSettings.paymentBrands = @"AMAZONPAY";
    
// Set Amazon Pay brand configuration
[checkoutSettings setBrandConfig:amazonPayConfig];

let checkoutSettings = OPPCheckoutSettings()
    
// Set Amazon Pay payment methods
checkoutSettings.paymentBrands = "AMAZONPAY"

// Set Amazon Pay brand configuration
checkoutSettings.setBrandConfig(amazonPayConfig)

1. Create AmazonPay Config

Create AmazonPay config and set it to brand configuration using CheckoutPaymentBrandConfig.Builder.

AmazonPayConfig amazonPayConfig = new AmazonPayConfig(AmazonPayConfig.AmazonPayRegion.US);
CheckoutPaymentBrandConfig brandConfig = new CheckoutPaymentBrandConfig.Builder()
                .setAmazonPayConfig(amazonPayConfig)
                .build();

val amazonPayConfig = AmazonPayConfig(AmazonPayConfig.AmazonPayRegion.US)
val brandConfig = CheckoutPaymentBrandConfig.Builder()
    .setAmazonPayConfig(amazonPayConfig)
    .build()

2. Create CheckoutSettings

Create CheckoutSettings and set brand configuration.

Set<String> paymentBrands = new LinkedHashSet<String>();
paymentBrands.add("AMAZONPAY");
CheckoutSettings checkoutSettings = new CheckoutSettings(checkoutId, paymentBrands, Connect.ProviderMode.TEST);
checkoutSettings.setBrandConfig(brandConfig);

val paymentBrands = hashSetOf("AMAZONPAY") 
val checkoutSettings = CheckoutSettings(checkoutId, paymentBrands, Connect.ProviderMode.TEST)
checkoutSettings.setBrandConfig(brandConfig)

SDK & Your Own UI

In this guide we assume that you have already implemented all steps for performing standard mSDK transaction.

There are several steps that you have to perform to integrate Amazon Pay, which are as follows:

1. Create AmazonPay brand configuration

Create AmazonPay brand configuration with AmazonPayConfig.AmazonPayRegion.

OPPAmazonPayConfig *brandConfig = [[OPPAmazonPayConfig alloc] initWithRegion:OPPAmazonPayRegionUS];

let config = OPPAmazonPayConfig(region: .US)

2. Create AmazonPay payment param

Use checkoutId and brandConfiguration object created earlier to create AmazonPay Payment params.

NSError *error;
OPPAmazonPayPaymentParams *params = [OPPAmazonPayPaymentParams amazonPayPaymentParamsWithCheckoutID:checkoutID
                                                                                      configuration:brandConfig
                                                                                              error:error];
params.shopperResultURL = @"com.companyname.appname.payments://result";

var params: OPPAmazonPayPaymentParams
do {
      params = try OPPAmazonPayPaymentParams.amazonPayPaymentParamsWith(checkoutID: checkoutID, configuration: config)
      params.shopperResultURL = "com.companyname.appname.payments://result"
} catch let error as NSError {
      // Handle the error.
}

3. Submit transaction

Create a payment provider object and call submit transaction.

OPPTransaction *transaction = [OPPTransaction transactionWithPaymentParams:params];
OPPPaymentProvider *provider = [OPPPaymentProvider paymentProviderWithMode:providerMode];
[self.provider submitTransaction:transaction completionHandler:^(OPPTransaction * _Nonnull transaction, NSError * _Nullable error) {
    // Use transaction.redirectURL to get universal link to present AmazonPay.
}];

let transaction = OPPTransaction(paymentParams: params)
let provider = OPPPaymentProvider(mode: providerMode)
let transaction = OPPTransaction(paymentParams: params)
provider.submitTransaction(transaction) { (transaction, error) in
    // Use transaction.redirectURL to get universal link to present AmazonPay.
}

4. Redirect to AmazonPay

Use transaction.redirectURL to present AmazonPay in Amazon shopping app or Safari browser to complete the transaction.

NSURL *redirectURL = transaction.redirectURL;
NSString *amazonAppName = @"com.amazon.mobile.shopping://";
NSURL *amazonAppUrl = [NSURL URLWithString:amazonAppName];
if ([[UIApplication sharedApplication] canOpenURL:amazonAppUrl]) {
    [[UIApplication sharedApplication] openURL:URL];
} else {
    SFSafariViewController *safariVc = [[SFSafariViewController alloc] initWithURL:URL];
    safariVc.delegate = delegate;
    [self presentViewController:vc animated:YES completion:nil];
}

let amazonAppName = "com.amazon.mobile.shopping://"
if let amazonAppUrl = URL(string: amazonAppName),
     UIApplication.shared.canOpenURL(amazonAppUrl) {
     UIApplication.shared.open(url)
} else {
     self.safariVC = SFSafariViewController(url: url)
     self.safariVC?.delegate = self
     self.present(safariVC!, animated: true, completion: nil)
}

NOTE: A server-to-server FI call needs to be initiated which is further sent to Amazon Pay. This returns an Amazon Pay URL to which the shopper is expected to be redirected. Once redirected, Amazon Pay processes the transaction and redirects the shopper back to the merchant application.

5. Get the payment status

Finally your app should request the payment status from your server.

For more details you can refer to this document.

1. Create AmazonPay brand configuration

Create AmazonPay brand configuration with AmazonPayConfig.AmazonPayRegion.

AmazonPayConfig amazonPayConfig = new AmazonPayConfig(AmazonPayConfig.AmazonPayRegion.US);

val amazonPayConfig = AmazonPayConfig(AmazonPayConfig.AmazonPayRegion.US)

2. Create AmazonPay payment param and submit transaction

Use checkoutId and amazonPayConfig(AmazonPayConfig) object created earlier in step -> 1 to create AmazonPay Payment params.

AmazonPayPaymentParams paymentParams = new AmazonPayPaymentParams(checkoutId, amazonPayConfig);
paymentParams.setShopperResultUrl("com.companyname.appname.payments://result");
	
//Create Transaction object by passing AmazonPayPaymentParams, then create payment provider object and call submit transaction
Transaction transaction = new Transaction(paymentParams);
OppPaymentProvider paymentProvider = new OppPaymentProvider(this, Connect.ProviderMode.TEST);
paymentProvider.submitTransaction(transaction, this);

val paymentParams = AmazonPayPaymentParams(checkoutId, amazonPayConfig)
paymentParams.shopperResultUrl = "com.companyname.appname.payments://result"

//Create Transaction object by passing AmazonPayPaymentParams, then create payment provider object and call submit transaction.
val transaction = Transaction(paymentParams)
val paymentProvider = OppPaymentProvider(this, Connect.ProviderMode.TEST)
paymentProvider.submitTransaction(transaction, this)

3. Implement ITransactionListener

Now, let the class implement the ITransactionListener interface. Implement the following ITransactionListener methods:

 
    @Override
    public void transactionCompleted(Transaction transaction) {
      // method which has been created in step 4 would be called here
      if ("AMAZONPAY".equals(transaction.getPaymentParams().getPaymentBrand())){
          redirectUsingUniversalLink(transaction.getRedirectUrl());
      } else {
        // code for other brands
      }
    }

    @Override
    public void transactionFailed(@NonNull Transaction transaction, @NonNull PaymentError error) {
       // show error message
    }


override fun transactionCompleted(transaction: Transaction) {
    // method which has been created in step 4 would be called here
    if ("AMAZONPAY" == transaction.paymentParams.paymentBrand) {
        redirectUsingUniversalLink(transaction.redirectUrl)
    } else {
     // code for other brands
   }
}

override fun transactionFailed(transaction: Transaction, error: PaymentError) {
    // show error message
}

4. Redirect to AmazonPay

In transactionCompleted() method that you have overriden in step -> 3, call this below method inside it.

public void redirectUsingUniversalLink(String url) {
        String amazonPackageName = "com.amazon.mShop.android.shopping";
        boolean isAmazonAppInstalled;

        try {
            getPackageManager().getPackageInfo(amazonPackageName, PackageManager.GET_ACTIVITIES);
            isAmazonAppInstalled = true;
        } catch (PackageManager.NameNotFoundException e) {
            isAmazonAppInstalled = false;
        }

        if (isAmazonAppInstalled) {
           // if amazon shopping app is available on user device, it will open the app
           Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
           startActivity(intent);
        } else {
          //  else you have to open the url in chrome custom tab
          CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder();
          builder.setShareState(CustomTabsIntent.SHARE_STATE_OFF);
          CustomTabsIntent tabIntent = builder.build();
          tabIntent.launchUrl(context, url);
        }
    }

fun redirectUsingUniversalLink(url: String) {
    val amazonPackageName = "com.amazon.mShop.android.shopping"
    val isAmazonAppInstalled: Boolean = try {
        packageManager.getPackageInfo(amazonPackageName, PackageManager.GET_ACTIVITIES)
        true
    } catch (e: PackageManager.NameNotFoundException) {
        false
    }

    if (isAmazonAppInstalled) {
        // if amazon shopping app is available on user device, it will open the app
        val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
        startActivity(intent)
    } else {
        //else you have to open the url in chrome custom tab
        val builder = CustomTabsIntent.Builder()
        builder.setShareState(CustomTabsIntent.SHARE_STATE_OFF)
        val tabIntent = builder.build()
        tabIntent.launchUrl(context, url)
     }
 }
