amazon-pay-api-sdk-java's Introduction

Maven Central

Amazon Pay API SDK (Java)

Amazon Pay Integration

Requirements

SDK Installation

To use the SDK in a Maven project, add a reference in your pom.xml file's section:

<dependencies>
    <dependency>
        <groupId>software.amazon.pay</groupId>
        <artifactId>amazon-pay-api-sdk-java</artifactId>
        <version>2.6.2</version>
    </dependency>
</dependencies>

To use the SDK in a Gradle project, add the following line to your build.gradle file::

implementation 'software.amazon.pay:amazon-pay-api-sdk-java:2.6.2'

For legacy projects, you can just grab the binary jar file from the GitHub Releases page.

Public and Private Keys

MWS access keys, MWS secret keys, and MWS authorization tokens from previous MWS-based integrations cannot be used with this SDK.

You will need to generate your own public/private key pair to make API calls with this SDK.

In Windows 10 this can be done with ssh-keygen commands:

ssh-keygen -t rsa -b 2048 -f private.pem
ssh-keygen -f private.pem -e -m PKCS8 > public.pub

In Linux or macOS this can be done using openssl commands:

openssl genrsa -out private.txt 2048
openssl rsa -in private.txt -pubout > public.pub

The first command above generates a private key and the second line uses the private key to generate a public key.

To associate the key with your account, follow the instructions here to Get your Public Key ID.

Namespace

Namespace for this package is com.amazon.pay.api to differentiate this SDK from the original Amazon Pay MWS SDK that uses just the com.amazon.pay namespace.

Here are some common imports you may need depending on your situation:

import com.amazon.pay.api.AmazonPayClient;
import com.amazon.pay.api.AmazonPayResponse;
import com.amazon.pay.api.InstoreClient; // not needed if using WebstoreClient
import com.amazon.pay.api.PayConfiguration;
import com.amazon.pay.api.RequestSigner; // not needed if using WebstoreClient
import com.amazon.pay.api.WebstoreClient;
import com.amazon.pay.api.exceptions.AmazonPayClientException;
import com.amazon.pay.api.types.Environment;
import com.amazon.pay.api.types.Region;

// to construct/parse arbitrary JSON objects
import org.json.JSONArray;
import org.json.JSONObject;

// for generating an idempotency key
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

// for loading your private key
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;

Versioning

The pay-api.amazon.com|eu|jp endpoint uses versioning to allow future updates. The major version of this SDK will stay aligned with the API version of the endpoint.

If you are using version 1.x.y of this SDK, $version in below examples would be "v1". 2.x.y would be "v2", etc.

Configuration

You will need your public key id and the file path to your private key.

You will need to specify either Environment.SANDBOX for Sandbox mode, or Environment.LIVE for Production mode.

PayConfiguration payConfiguration = null;
try {
    payConfiguration = new PayConfiguration()
                .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                .setRegion(Region.YOUR_REGION_CODE)
                .setPrivateKey("YOUR_PRIVATE_KEY_STRING".toCharArray())
                .setEnvironment(Environment.SANDBOX)
                .setAlgorithm("AMZN-PAY-RSASSA-PSS-V2"); // Amazon Signing Algorithm, Optional: uses AMZN-PAY-RSASSA-PSS if not specified
} catch (AmazonPayClientException e) {
    e.printStackTrace();
}

// If you have created envrionment specific keys (i.e Public Key Starts with LIVE or SANDBOX) in seller central, then use those PublicKeyId & PrivateKey. In this case, no need to set Environment
PayConfiguration payConfiguration = null;
try {
    payConfiguration = new PayConfiguration()
                .setPublicKeyId("YOUR_PUBLIC_KEY_ID") // LIVE-XXXXX or SANDBOX-XXXXX
                .setRegion(Region.YOUR_REGION_CODE)
                .setPrivateKey("YOUR_PRIVATE_KEY_STRING".toCharArray())
                .setAlgorithm('AMZN-PAY-RSASSA-PSS-V2'); // Amazon Signing Algorithm, Optional: uses AMZN-PAY-RSASSA-PSS if not specified
} catch (AmazonPayClientException e) {
    e.printStackTrace();
}

// If you have your private key in a file, you can set it in the payConfiguration in the following way:

try {
    payConfiguration = new PayConfiguration()
                   .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                   .setRegion(Region.YOUR_REGION_CODE)
                   .setPrivateKey(new String(Files.readAllBytes(Paths.get("private.pem"))).toCharArray())
                   .setEnvironment(Environment.SANDBOX)
                   .setAlgorithm('AMZN-PAY-RSASSA-PSS-V2'); // Amazon Signing Algorithm, Optional: uses AMZN-PAY-RSASSA-PSS if not specified
} catch (AmazonPayClientException e) {
     e.printStackTrace();
}

// You can also set your private key as a java.security.PrivateKey object

PrivateKey privateKey = ...

try {
    payConfiguration = new PayConfiguration()
                .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                .setRegion(Region.YOUR_REGION_CODE)
                .setPrivateKey(privateKey)
                .setEnvironment(Environment.SANDBOX)
                .setAlgorithm('AMZN-PAY-RSASSA-PSS-V2'); // Amazon Signing Algorithm, Optional: uses AMZN-PAY-RSASSA-PSS if not specified
} catch (AmazonPayClientException e) {
     e.printStackTrace();
}

// If you have want to enable proxy support, you can set it in the payConfiguration in the following way:

try {
    ProxySettings proxySettings = new ProxySettings()
                .setProxyHost("localhost")
                .setProxyPort(8080)
                .setProxyUser("user")
                .setProxyPassword("password".toCharArray());
    
    payConfiguration = new PayConfiguration()
                   .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                   .setRegion(Region.YOUR_REGION_CODE)

                   .setEnvironment(Environment.SANDBOX)
                   .setAlgorithm('AMZN-PAY-RSASSA-PSS-V2'); // Amazon Signing Algorithm, Optional: uses AMZN-PAY-RSASSA-PSS if not specified
                   .setProxySettings(proxySettings);
} catch (AmazonPayClientException e) {
     e.printStackTrace();
}

// If you want to enable the Custom Connection Pool, you can set it in the payConfiguration in the following way:

try {
    int MAX_CLIENT_CONNECTIONS = 30; // This value should be decided according to your requirement
    payConfiguration = new PayConfiguration()
                    .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                    .setRegion(Region.YOUR_REGION_CODE) 
                    .setPrivateKey("YOUR_PRIVATE_KEY_STRING".toCharArray())
                    .setEnvironment(Environment.SANDBOX)
                    .setClientConnections(MAX_CLIENT_CONNECTIONS); // Default is set to 20
} catch (AmazonPayClientException e) {
    e.printStackTrace();
}

// If you want to set client request configuration, connection, connect and socket timeout, the payConfiguration looks like below:

try {
    payConfiguration = new PayConfiguration()
                    .setPublicKeyId("YOUR_PUBLIC_KEY_ID")
                    .setRegion(Region.YOUR_REGION_CODE)
                    .setPrivateKey("YOUR_PRIVATE_KEY_STRING".toCharArray())
                    .setEnvironment(Environment.SANDBOX)
                    .setRequestConfig(new RequestConfig(1000, 2000, 4000);//connection timeout = 1s, connect timeout = 2s, socket timeout = 4s
} catch (AmazonPayClientException e) {
    e.printStackTrace();
}

Convenience Functions (Overview)

Make use of the built-in convenience functions to easily make API calls. Scroll down further to see example code snippets.

When using the convenience functions, the request payload will be signed using the provided private key, and a HTTPS request is made to the correct regional endpoint. In the event of request throttling, the HTTPS call will be attempted up to three times using an exponential backoff approach.

Single Page Checkout API

  • WebstoreClient: finalizeCheckoutSession(String checkoutSessionId, JSONObject payload[, Map<String, String> header]) → POST to "$version/checkoutSessions/$checkoutSessionId/finalize"

Using Convenience Functions

Four quick steps are needed to make an API call:

Step 1. Construct a AmazonPayClient (using the previously defined PayConfiguration object).

AmazonPayClient client = new AmazonPayClient(payConfiguration);
    // -or-
WebstoreClient webstoreClient = new WebstoreClient(payConfiguration);
    // -or-
InstoreClient instoreClient = new InstoreClient(payConfiguration);

Step 2. Generate the payload.

JSONObject payload = new JSONObject();
payload.put("scanData", "UKhrmatMeKdlfY6b");
payload.put("scanReferenceId", "0b8fb271-2ae2-49a5-b35d890");
payload.put("merchantCOE", "DE");
payload.put("ledgerCurrency", "EUR");

Step 3. Execute the call.

AmazonPayResponse response = instoreClient.merchantScan(payload);

Step 4. Check the result.

response will be an object with the following getters:

  • 'getStatus()' - int HTTP status code (200, 201, etc.)
  • 'getResponse()' - the response serialized into a JSONObject
  • 'getRawResponse()' - the raw JSON String response body received from Amazon Pay
  • 'getRequestId()' - the Request ID from Amazon API gateway
  • 'getUrl()' - the URL for the REST call the SDK calls, for troubleshooting purposes
  • 'getMethod() - POST, GET, PATCH, or DELETE
  • 'getHeaders()' - an Map<String, String> containing the various headers generated by the SDK, for troubleshooting purposes
  • 'getRawRequest()' - the JSON request body String sent to Amazon Pay
  • 'getRetries()' - usually 0, but reflects the number of times a request was retried due to throttling or other server-side issue
  • 'getDuration()' - duration in milliseconds of SDK function call
  • 'isSuccess()' - returns true for a 200, 201, or 202 HTTP status; false otherwise

The first two items (status, response) are critical. The remaining items are useful in troubleshooting situations.

If you are a Solution Provider and need to make an API call on behalf of a different merchant account, you will need to pass along an extra authentication token parameter into the API call.

Convenience Functions Code Samples

Generate Button Signature (helper function)

This method is available in the base client ("AmazonPayClient"). This method does not invoke an API call, it is a helper function only.

The signatures generated by this helper function are only valid for the Checkout v2 front-end buttons. Unlike API signing, no timestamps are involved, so the result of this function can be considered a static signature that can safely be placed in your website JS source files and used repeatedly (as long as your payload does not change).

    String payload = "{\"storeId\":\"amzn1.application-oa2-client.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\",\"webCheckoutDetails\":{\"checkoutReviewReturnUrl\":\"https://localhost/test/CheckoutReview.php\",\"checkoutResultReturnUrl\":\"https://localhost/test/CheckoutResult.php\"}}";
    String signature = client.generateButtonSignature(payload);

Or, if you want to use a JSONObject:

        JSONObject payload = new JSONObject();
        payload.put("storeId", "amzn1.application-oa2-client.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
        JSONObject webCheckoutDetails = new JSONObject();
        webCheckoutDetails.put("checkoutReviewReturnUrl", "https://localhost/test/CheckoutReview.php");
        webCheckoutDetails.put("checkoutResultReturnUrl", "https://localhost/test/CheckoutResult.php");
        payload.put("webCheckoutDetails", webCheckoutDetails);

        String signature = client.generateButtonSignature(payload);

Please note that your Solution Provider account must have a pre-existing relationship (valid and active API V1-style MWS authorization token) with the merchant account in order to use this function.

AmazonPayClient client;
PayConfiguration payConfiguration;
AmazonPayResponse response;
String mwsAuthToken = /* the third part mws auth token */;
String merchantId = /* the third party merchant id */; 
String privateKey = /* your private key */;
String publicKeyId = /* your public key id */;
try {
    payConfiguration = new PayConfiguration();
    payConfiguration.setRegion(Region.EU). // select your region
            setEnvironment(Environment.LIVE). // must be live
            setPrivateKey(privateKey).
            setPublicKeyId(publicKeyId);

    client = new AmazonPayClient(payConfiguration);
    response = client.getAuthorizationToken(mwsAuthToken, merchantId, null);
    // If OK response.getStatus() shall be 200
    // If OK response.getResponse() provides the mwsAuthToken
} catch (Exception e) {
    // System.out.println(e.getMessage());
    /* handle Exception here */
}

Manual Signing (Advanced Use-Cases Only)

This SDK provides the ability to help you manually sign your API requests if you want to use your own code for sending the HTTPS request over the Internet.

}

HttpURLConnection conn = (HttpURLConnection)scanUri.toURL().openConnection();

for (Map.Entry<String, String> entry : postSignedHeaders.entrySet()) {
