You can sign up for a Stripe account at https://stripe.com.

Java 1.7 or later.

Add this dependency to your project's POM:

<dependency>
  <groupId>com.stripe</groupId>
  <artifactId>stripe-java</artifactId>
  <version>6.3.0</version>
</dependency>

Add this dependency to your project's build file:

compile "com.stripe:stripe-java:6.3.0"

You'll need to manually install the following JARs:

• The Stripe JAR from https://github.com/stripe/stripe-java/releases/latest
• Google Gson from https://repo1.maven.org/maven2/com/google/code/gson/gson/2.8.2/gson-2.8.2.jar.

If you're planning on using ProGuard, make sure that you exclude the Stripe bindings. You can do this by adding the following to your proguard.cfg file:

-keep class com.stripe.** { *; }

Please see the Java API docs for the most up-to-date documentation.

StripeExample.java

import java.util.HashMap;
import java.util.Map;

import com.stripe.Stripe;
import com.stripe.exception.StripeException;
import com.stripe.model.Charge;
import com.stripe.net.RequestOptions;

public class StripeExample {

    public static void main(String[] args) {
        Stripe.apiKey = "sk_test_...";

        Map<String, Object> chargeMap = new HashMap<String, Object>();
        chargeMap.put("amount", 100);
        chargeMap.put("currency", "usd");
        chargeMap.put("source", "tok_1234"); // obtained via Stripe.js

        try {
            Charge charge = Charge.create(chargeMap);
            System.out.println(charge);
        } catch (StripeException e) {
            e.printStackTrace();
        }
    }
}

See the project's functional tests for more examples.

For apps that need to use multiple keys during the lifetime of a process, like one that uses Stripe Connect, it's also possible to set a per-request key and/or account:

RequestOptions requestOptions = new RequestOptionsBuilder()
    .setApiKey("sk_test_...")
    .setStripeAccount("acct_...")
    .build();

Charge.list(null, requestOptions);

Charge.retrieve("ch_18atAXCdGbJFKhCuBAa4532Z", requestOptions);

Connect and read timeouts can be configured globally:

Stripe.setConnectTimeout(30 * 1000); // in milliseconds
Stripe.setReadTimeout(80 * 1000);

Or on a finer grain level using RequestOptions:

RequestOptions options = RequestOptions.builder()
    .setConnectTimeout(30 * 1000) // in milliseconds
    .setReadTimeout(80 * 1000)
    .build();
Charge.create(params, options);

Please take care to set conservative read timeouts. Some API requests can take some time, and a short timeout increases the likelihood of a problem within our servers.

If you're writing a plugin that uses the library, we'd appreciate it if you identified using Stripe.setAppInfo():

Stripe.setAppInfo("MyAwesomePlugin", "1.2.34", "https://myawesomeplugin.info");

This information is passed along when the library makes calls to the Stripe API.

The test suite depends on stripe-mock, so make sure to fetch and run it from a background terminal (stripe-mock's README also contains instructions for installing via Homebrew and other methods):

go get -u github.com/stripe/stripe-mock
stripe-mock

You must have Gradle installed. To run the tests:

./gradlew test

You can run particular tests by passing --tests Class#method. Make sure you use the fully qualified class name. For example:

./gradlew test --tests com.stripe.model.AccountTest
./gradlew test --tests com.stripe.functional.ChargeTest
./gradlew test --tests com.stripe.functional.ChargeTest.testChargeCreate

The library uses Project Lombok. While it is not a requirement, you might want to install a plugin for your favorite IDE to facilitate development.
