The official Stripe Java client library allows you to interact seamlessly with the Stripe API. Whether you are creating customers, managing payments, or using advanced features, this library simplifies the process. In this article, we will guide you through installing and utilizing the Stripe Java client library effectively.

Installation

To begin, ensure that you meet the following requirements:

• Java 1.8 or later

Adding the Dependency

For Gradle Users

Add this dependency to your project’s build file:

implementation 'com.stripe:stripe-java:27.1.0'

For Maven Users

Add this dependency to your project’s POM:

<dependency>
    <groupId>com.stripe</groupId>
    <artifactId>stripe-java</artifactId>
    <version>27.1.0</version>
</dependency>

Other Installation Methods

If you prefer, you can manually install the required JARs:

• The Stripe JAR
• Google Gson

ProGuard Configuration

If you’re using ProGuard, ensure to exclude the Stripe client library by adding the following to your proguard.cfg file:

-keep class com.stripe.**  *;

Using the Library

Once installed, you can start making requests to the Stripe API. Let’s consider an analogy of a restaurant customer relationship. Here, creating a customer in Stripe is like the restaurant taking down your details for a reservation.

Example Code

Below is a simple example of how to create a customer using the library:

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("test@example.com")
            .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();
        }
    }
}

In this analogy, the StripeClient represents the restaurant itself, and the CustomerCreateParams is similar to the details collected for your reservation (like your name and contact number). When you call client.customers().create(params), it’s equivalent to the restaurant confirming your reservation based on the provided details.

Troubleshooting

Here are some common issues and their resolutions:

• Network Issues: If you encounter intermittent network problems, ensure that you have configured the library to automatically retry requests, as discussed in the usage section.
• Timeouts: If you’re receiving timeout errors, consider adjusting your connect and read timeouts to accommodate longer response times.
• Using Undocumented Features: The library supports undocumented parameters using putExtraParam(). Ensure you are familiar with this method if you’re accessing beta features.
