## Usage

### API Usage

```java
import com.apple.itunes.storekit.client.APIException;
import com.apple.itunes.storekit.client.AppStoreServerAPIClient;
import com.apple.itunes.storekit.model.Environment;
import com.apple.itunes.storekit.model.SendTestNotificationResponse;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;

public class APIExample {
    public static void main(String[] args) throws Exception {
        String issuerId = "99b16628-15e4-4668-972b-eeff55eeff55";
        String keyId = "ABCDEFGHIJ";
        String bundleId = "com.example";
        Path filePath = Path.of("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8");
        String encodedKey = Files.readString(filePath);
        Environment environment = Environment.SANDBOX;

        AppStoreServerAPIClient client =
                new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment);

        try {
            SendTestNotificationResponse response = client.requestTestNotification();
            System.out.println(response);
        } catch (APIException | IOException e) {
            e.printStackTrace();
        }
    }
}
```

### Verification Usage

```java
import com.apple.itunes.storekit.model.Environment;
import com.apple.itunes.storekit.model.ResponseBodyV2DecodedPayload;
import com.apple.itunes.storekit.verification.SignedDataVerifier;
import com.apple.itunes.storekit.verification.VerificationException;

import java.io.FileInputStream;
import java.io.InputStream;
import java.util.Set;

public class ExampleVerification {
    public static void main(String[] args) {
        String bundleId = "com.example";
        Environment environment = Environment.SANDBOX;
        Set<InputStream> rootCAs = Set.of(
                new FileInputStream("/path/to/rootCA1"),
                new FileInputStream("/path/to/rootCA2")
        );

        SignedDataVerifier signedPayloadVerifier = new SignedDataVerifier(rootCAs, bundleId, null, environment, true);
        
        String notificationPayload = "ey...";

        try {
            ResponseBodyV2DecodedPayload payload = signedPayloadVerifier.verifyAndDecodeNotification(notificationPayload);
            System.out.println(payload);
        } catch (VerificationException e) {
            e.printStackTrace();
        }
    }
}
```

### Receipt Usage

```java
import com.apple.itunes.storekit.client.AppStoreServerAPIClient;
import com.apple.itunes.storekit.migration.ReceiptUtility;
import com.apple.itunes.storekit.model.Environment;
import com.apple.itunes.storekit.model.HistoryResponse;
import com.apple.itunes.storekit.model.TransactionHistoryRequest;

import java.nio.file.Files;
import java.nio.file.Path;
import java.util.LinkedList;
import java.util.List;

public class ExampleMigration {
    public static void main(String[] args) throws Exception {
        String issuerId = "99b16628-15e4-4668-972b-eeff55eeff55";
        String keyId = "ABCDEFGHIJ";
        String bundleId = "com.example";
        Path filePath = Path.of("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8");
        String encodedKey = Files.readString(filePath);
        Environment environment = Environment.SANDBOX;

        AppStoreServerAPIClient client =
                new AppStoreServerAPIClient(encodedKey, keyId, issuerId, bundleId, environment);

        String appReceipt = "MI...";
        ReceiptUtility receiptUtil = new ReceiptUtility();
        String transactionId = receiptUtil.extractTransactionIdFromAppReceipt(appReceipt);
        if (transactionId != null) {
            TransactionHistoryRequest request = new TransactionHistoryRequest()
                    .sort(TransactionHistoryRequest.Order.ASCENDING)
                    .revoked(false)
                    .productTypes(List.of(TransactionHistoryRequest.ProductType.AUTO_RENEWABLE));
            HistoryResponse response = null;
            List<String> transactions = new LinkedList<>();
            do {
                String revision = response != null ? response.getRevision() : null;
                response = client.getTransactionHistory(transactionId, revision, request);
                transactions.addAll(response.getSignedTransactions());
            } while (response.getHasMore());
            System.out.println(transactions);
        }
    }
}
```

### Promotional Offer Signature Creation

```java
import com.apple.itunes.storekit.offers.PromotionalOfferSignatureCreator;

import java.nio.file.Files;
import java.nio.file.Path;
import java.util.UUID;

public class ExampleSignatureCreation {
    public static void main(String[] args) throws Exception {
        String keyId = "ABCDEFGHIJ";
        String bundleId = "com.example";
        Path filePath = Path.of("/path/to/key/SubscriptionKey_ABCDEFGHIJ.p8");
        String encodedKey = Files.readString(filePath);

        PromotionalOfferSignatureCreator signatureCreator = new PromotionalOfferSignatureCreator(encodedKey, keyId, bundleId);
        
        String productId = "<product_id>";
        String subscriptionOfferId = "<subscription_offer_id>";
        String applicationUsername = "<application_username>";
        UUID nonce = UUID.randomUUID();
        long timestamp = System.currentTimeMillis();
        String encodedSignature = signatureCreator.createSignature(productId, subscriptionOfferId, applicationUsername, nonce, timestamp);
        System.out.println(encodedSignature);
    }
}
```

## Support

Only the latest major version of the library will receive updates, including security updates. Therefore, it is recommended to update to new major versions.
