Stripe Java client library

Maven Central JavaDoc Build Status

The official Stripe Java client library.

Installation

Requirements

  • Java 1.8 or later

Gradle users

Add this dependency to your project's build file:

implementation "com.stripe:stripe-java:20.7.0"

Maven users

Add this dependency to your project's POM:

<dependency>
  <groupId>com.stripe</groupId>
  <artifactId>stripe-java</artifactId>
  <version>20.7.0</version>
</dependency>

Others

You'll need to manually install the following JARs:

ProGuard

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

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

Documentation

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

You can also refer to the online Javadoc.

Usage

StripeExample.java

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

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

public class StripeExample {

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

        Map<String, Object> customerMap = new HashMap<String, Object>();
        customerMap.put("description", "Example descriptipn");
        customerMap.put("email", "test@example.com");
        customerMap.put("payment_method", "pm_card_visa"); // obtained via Stripe.js

        try {
            Customer customer = Customer.create(customerMap);
            System.out.println(customer);
        } catch (StripeException e) {
            e.printStackTrace();
        }
    }
}

See the project's functional tests for more examples.

Per-request Configuration

All of the request methods accept an optional RequestOptions object. This is used if you want to set an idempotency key, if you are using Stripe Connect, or if you want to pass the secret API key on each method.

RequestOptions requestOptions = new RequestOptionsBuilder()
    .setApiKey("sk_test_...")
    .setIdempotencyKey("a1b2c3...")
    .setStripeAccount("acct_...")
    .build();

Customer.list(null, requestOptions);

Customer.retrieve("cus_123456789", requestOptions);

Configuring automatic retries

The library can be configured to automatically retry requests that fail due to an intermittent network problem or other knowingly non-deterministic errors. This can be enabled globally:

Stripe.setMaxNetworkRetries(2);

Or on a finer grain level using RequestOptions:

RequestOptions options = RequestOptions.builder()
    .setMaxNetworkRetries(2)
    .build();
Customer.create(params, options);

Idempotency keys are added to requests to guarantee that retries are safe.

Configuring Timeouts

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();
Customer.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.

Writing a plugin

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.

Request latency telemetry

By default, the library sends request latency telemetry to Stripe. These numbers help Stripe improve the overall latency of its API for all users.

You can disable this behavior if you prefer:

Stripe.enableTelemetry = false;

Development

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

To run all checks (tests and code formatting):

./gradlew check

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.CustomerTest
./gradlew test --tests com.stripe.functional.CustomerTest.testCustomerCreate

The library uses Spotless along with google-java-format for code formatting. Code must be formatted before PRs are submitted, otherwise CI will fail. Run the formatter with:

./gradlew spotlessApply

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.
