### Client Instantiation

Source: https://context7.com/square/square-java-sdk/llms.txt

Demonstrates how to instantiate the synchronous SquareClient using various configuration options, including environment selection, explicit token, timeouts, retry limits, custom HTTP clients, and headers.

```APIDOC
## Client Instantiation — `SquareClient.builder()`

The entry point for all API calls; credentials can be supplied explicitly or read from the `SQUARE_TOKEN` environment variable. The builder exposes environment selection, custom base URLs, timeout, retry limits, custom HTTP client, and custom headers.

```java
import com.squareup.square.SquareClient;
import com.squareup.square.core.Environment;
import com.squareup.square.core.RequestOptions;
import okhttp3.OkHttpClient;

// Minimal — token from env var SQUARE_TOKEN
SquareClient client = SquareClient.builder().build();

// Explicit token + sandbox environment
SquareClient client = SquareClient.builder()
    .token("YOUR_SQUARE_TOKEN")
    .environment(Environment.SANDBOX)
    .build();

// Full customisation
OkHttpClient httpClient = new OkHttpClient.Builder()
    .connectTimeout(30, java.util.concurrent.TimeUnit.SECONDS)
    .build();

SquareClient client = SquareClient.builder()
    .token("YOUR_SQUARE_TOKEN")
    .environment(Environment.PRODUCTION)
    .timeout(60)           // seconds
    .maxRetries(3)
    .httpClient(httpClient)
    .addHeader("X-App-Version", "2.0.0")
    .build();
```
```

### Start Transfer Order in Java

Source: https://github.com/square/square-java-sdk/blob/master/reference.md

Use this to change a DRAFT transfer order to STARTED status. This action decrements inventory at the source location and marks it as in-transit. The order must be in DRAFT status and cannot be deleted after being started. An idempotency key is required for this operation.

```java
client.transferOrders().start(
    StartTransferOrderRequest
        .builder()
        .transferOrderId("transfer_order_id")
        .idempotencyKey("EXAMPLE_IDEMPOTENCY_KEY_789")
        .version(1753109537351L)
        .build()
);
```

### Instantiate New and Legacy Square SDK Clients

Source: https://context7.com/square/square-java-sdk/llms.txt

Demonstrates how to instantiate both the new Square SDK client and the legacy Square SDK client. Use the new client for new code paths and the legacy client for existing ones during the migration process.

```java
import com.squareup.square.SquareClient;
import com.squareup.square.core.Environment;

// New SDK client
SquareClient newClient = SquareClient.builder()
    .environment(Environment.PRODUCTION)
    .token("YOUR_TOKEN")
    .build();

// Legacy SDK client (same token, old builder pattern)
com.squareup.square.legacy.SquareClient legacyClient =
    new com.squareup.square.legacy.SquareClient.Builder()
        .environment(com.squareup.square.legacy.Environment.PRODUCTION)
        .accessToken("YOUR_TOKEN")
        .build();

// Use new client for new code paths, legacy client for existing ones
newClient.payments().list().streamItems().forEach(p -> System.out.println(p.getId()));
legacyClient.getPaymentsApi().listPayments(null, null, null, null, null, null, null, null, null);
```
