Checkout.com Java SDK

Getting started

Version 6.0.0 is here!

We improved the initialization of SDK making it easier to understand the available options.
Now NAS accounts are the default instance for the SDK and ABC structure was moved to a previous prefixes.
If you have been using this SDK before, you may find the following important changes:

Marketplace module was moved to Accounts module, same for classes and references.

In most cases, IDE can help you determine from where to import, but if you’re still having issues don't hesitate to open a ticket.

How to use the SDK

This SDK can be used with two different pair of API keys provided by Checkout. However, using different API keys imply using specific API features. Please find in the table below the types of keys that can be used within this SDK.

Account System	Public Key (example)	Secret Key (example)
Default	pk_pkhpdtvabcf7hdgpwnbhw7r2uic	sk_m73dzypy7cf3gf5d2xr4k7sxo4e
Previous	pk_g650ff27-7c42-4ce1-ae90-5691a188ee7b	sk_gk3517a8-3z01-45fq-b4bd-4282384b0a64

Note: sandbox keys have a sbox_ or test_ identifier, for Default and Previous accounts respectively.

If you don't have your own API keys, you can sign up for a test account here.

PLEASE NEVER SHARE OR PUBLISH YOUR CHECKOUT CREDENTIALS.

Default

Default keys client instantiation can be done as follows:

import com.checkout.CheckoutApi;

public static void main(String[] args) {
    
    final CheckoutApi checkoutApi = CheckoutSdk.builder()
            .staticKeys()
            .publicKey("public_key")  // optional, only required for operations related with tokens
            .secretKey("secret_key")
            .environment(Environment.PRODUCTION)  // required
            .executor() // optional for a custom Executor Service
            .build();
    
    final PaymentsClient client = checkoutApi.paymentsClient();
    
    final CompletableFuture<RefundResponse> refundPayment = client.refundPayment("payment_id");
}

Default OAuth

The SDK supports client credentials OAuth, when initialized as follows:

import com.checkout.CheckoutApi;

public static void main(String[] args) {

final CheckoutApi checkoutApi = CheckoutSdk.builder()
        .oAuth()
        .clientCredentials("client_id", "client_secret")
        // for a specific authorization endpoint
        //.clientCredentials(new URI("https://access.sandbox.checkout.com/connect/token"), "client_id", "client_secret")
        .scopes(OAuthScope.GATEWAY, OAuthScope.VAULT, OAuthScope.FX)
        .environment(Environment.PRODUCTION)  // required
        .executor() // optional for a custom Executor Service
        .build();

final PaymentsClient client = checkoutApi.paymentsClient();

final CompletableFuture<RefundResponse> refundPayment = client.refundPayment("payment_id");
        }

If your pair of keys matches the Previous type, this is how the SDK should be used:

import com.checkout.previous.CheckoutApi;

public static void main(String[] args) {
    final CheckoutApi checkoutApi = CheckoutSdk.builder()
            .previous()
            .staticKeys()
            .publicKey("public_key")  // optional, only required for operations related with tokens
            .secretKey("secret_key")
            .environment(Environment.PRODUCTION)  // required
            .executor() // optional for a custom Executor Service
            .build();
    
    final PaymentsClient client = checkoutApi.paymentsClient();
    
    final CompletableFuture<RefundResponse> refundPayment = client.refundPayment("payment_id");
        }

Exception handling

All the API responses that do not fall in the 2** status codes will cause a CheckoutApiException. The exception encapsulates the requestId, httpStatusCode and a map of errorDetails, if available.

Building from source

Once you check out the code from GitHub, the project can be built using Gradle:

gradlew build

# skip tests
gradlew build -x test

The execution of integration tests require the following environment variables set in your system:

For default account systems: CHECKOUT_DEFAULT_PUBLIC_KEY & CHECKOUT_DEFAULT_SECRET_KEY
For default account systems (OAuth): CHECKOUT_DEFAULT_OAUTH_CLIENT_ID & CHECKOUT_DEFAULT_OAUTH_CLIENT_SECRET
For Previous account systems: CHECKOUT_PREVIOUS_PUBLIC_KEY & CHECKOUT_PREVIOUS_SECRET_KEY
