The official [Stripe][stripe] Java client library.



## Installation



### Requirements



- Java 1.8 or later



### Gradle users



Add this dependency to your project's build file:



```groovy

implementation "com.stripe:stripe-java:26.5.1"

```



### Maven users



Add this dependency to your project's POM:



```xml



  com.stripe

  stripe-java

  26.5.1



```



### Others



You'll need to manually install the following JARs:



- [The Stripe JAR](https://search.maven.org/remotecontent?filepath=com/stripe/stripe-java/26.5.1/stripe-java-26.5.1.jar)

- [Google Gson][gson] from .



### [ProGuard][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][api-docs] for the most

up-to-date documentation.



See [video demonstrations][youtube-playlist] covering how to use the library.



You can also refer to the [online Javadoc][javadoc].



## Usage



StripeExample.java



```java

import java.util.HashMap;

import java.util.Map;



import com.stripe.StripeClient;

import com.stripe.exception.StripeException;

import com.stripe.model.Customer;

import com.stripe.net.RequestOptions;

import com.stripe.param.CustomerCreateParams;



public class StripeExample {



    public static void main(String[] args) {

        StripeClient client = new StripeClient("sk_test_...");

        CustomerCreateParams params =

            CustomerCreateParams

                .builder()

                .setDescription("Example description")

                .setEmail("[email protected]")

                .setPaymentMethod("pm_card_visa")  // obtained via Stripe.js

                .build();



        try {

            Customer customer = client.customers().create(params);

            System.out.println(customer);

        } catch (StripeException e) {

            e.printStackTrace();

        }

    }

}

```



See the project's [functional tests][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][idempotency-keys], if you are

using [Stripe Connect][connect-auth], or if you want to pass the secret API

key on each method.



```java

RequestOptions requestOptions = RequestOptions.builder()

    .setApiKey("sk_test_...")

    .setIdempotencyKey("a1b2c3...")

    .setStripeAccount("acct_...")

    .build();



client.customers().list(requestOptions);



client.customers().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:



```java

StripeClient client = StripeClient.builder()

        .setMaxNetworkRetries(2)

        .build();

```



Or on a finer grain level using `RequestOptions`:



```java

RequestOptions options = RequestOptions.builder()

    .setMaxNetworkRetries(2)

    .build();

client.customers().create(params, options);

```



[Idempotency keys][idempotency-keys] are added to requests to guarantee that

retries are safe.



### Configuring Timeouts



Connect and read timeouts can be configured globally:



```java

StripeClient client = StripeClient.builder()

        .setConnectTimeout(30 * 1000); // in milliseconds

        .setReadTimeout(80 * 1000);

        .build();

```



Or on a finer grain level using `RequestOptions`:



```java

RequestOptions options = RequestOptions.builder()

    .setConnectTimeout(30 * 1000) // in milliseconds

    .setReadTimeout(80 * 1000)

    .build();

client.customers().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.



### Configuring DNS Cache TTL



We cannot guarantee that the IP address of the Stripe API will be static.

Commonly, default JVM configurations can have their DNS cache TTL set to

forever. If Stripe's IP address changes, your application's requests to

Stripe will all fail until the JVM restarts. Therefore we recommend that

you modify the JVM's [networkaddress.cache.ttl

property](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/net/doc-files/net-properties.html)

to `60` seconds.



### How to use undocumented parameters and properties



stripe-java is a typed library and it supports all public properties or parameters.



Stripe sometimes has beta which introduces new properties or parameters that are not immediately public. The library does not support these properties or parameters until they are public but there is still an approach that allows you to use them.



#### Parameters



To pass undocumented parameters to Stripe using stripe-java you need to use the `putExtraParam()` method, as shown below:



```java

CustomerCreateParams params =

  CustomerCreateParams.builder()

    .setEmail("[email protected]")

    .putExtraParam("secret_feature_enabled", "true")

    .putExtraParam("secret_parameter[primary]", "primary value")

    .putExtraParam("secret_parameter[secondary]", "secondary value")

    .build();



client.customers().create(params);

```



#### Properties



To retrieve undocumented properties from Stripe using Java you can use an option in the library to return the raw JSON object and return the property as a native type. An example of this is shown below:



```java

final Customer customer = client.customers().retrieve("cus_1234");

Boolean featureEnabled =

  customer.getRawJsonObject()

    .getAsJsonPrimitive("secret_feature_enabled")

    .getAsBoolean();

String primaryValue =

  customer.getRawJsonObject()

    .getAsJsonObject("secret_parameter")

    .getAsJsonPrimitive("primary")

    .getAsString();

String secondaryValue =

  customer.getRawJsonObject()

    .getAsJsonObject("secret_parameter")

    .getAsJsonPrimitive("secondary")

    .getAsString();

```



### Writing a plugin



If you're writing a plugin that uses the library, we'd appreciate it if you

identified using `Stripe.setAppInfo()`:



```java

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:



```java

Stripe.enableTelemetry = false;

```



### Beta SDKs



Stripe has features in the beta phase that can be accessed via the beta version of this package.

We would love for you to try these and share feedback with us before these features reach the stable phase.

To install a beta version of stripe-java follow steps [installation steps above](#installation) using the beta library version.



> **Note**

> There can be breaking changes between beta versions. Therefore we recommend pinning the package version to a specific version. This way you can install the same version each time without breaking changes unless you are intentionally looking for the latest beta version.



We highly recommend keeping an eye on when the beta feature you are interested in goes from beta to stable so that you can move from using a beta version of the SDK to the stable version.



If your beta feature requires a `Stripe-Version` header to be sent, set the `Stripe.stripeVersion` field by calling `Stripe.addBetaVersion`:



> **Note**

> Beta version headers can only be set in beta versions of the library.



```java

Stripe.addBetaVersion("feature_beta", "v3");

```



## Support



New features and bug fixes are released on the latest major version of the Stripe Java client library. If you are on an older major version, we recommend that you upgrade to the latest in order to use the new features and bug fixes including those for security vulnerabilities. Older major versions of the package will continue to be available for use, but will not be receiving any updates.



## Development



JDK 17 is required to build the Stripe Java library. By default, tests use the same Java runtime as the build.

To use a custom version of Java runtime for tests set the `JAVA_TEST_HOME` environment variable to runtime's

home directory.



The test suite depends on [stripe-mock], so make sure to fetch and run it from a

background terminal ([stripe-mock's README][stripe-mock] also contains

instructions for installing via Homebrew and other methods):



```sh

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

stripe-mock

```



To run all checks (tests and code formatting):



```sh

./gradlew check

```



To run the tests:



```sh

./gradlew test

```



You can run particular tests by passing `--tests Class#method`. Make sure you

use the fully qualified class name. For example:



```sh

./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][spotless] along with

[google-java-format][google-java-format] for code formatting. Code must be

formatted before PRs are submitted, otherwise CI will fail. Run the formatter

with:



```sh

./gradlew spotlessApply

```



The library uses [Project Lombok][lombok]. While it is not a requirement, you

might want to install a [plugin][lombok-plugins] for your favorite IDE to

facilitate development.
