        )

## Make Calls with the API Client

```php
<?php

require_once "vendor/autoload.php";

use Square\SquareClientBuilder;
use Square\Authentication\BearerAuthCredentialsBuilder;
use Square\Environment;

$client = SquareClientBuilder::init()
    ->bearerAuthCredentials(
        BearerAuthCredentialsBuilder::init(
            'AccessToken'
        )
    )
    ->squareVersion('2025-01-23')
    ->environment(Environment::PRODUCTION)
    ->customUrl('https://connect.squareup.com')
    ->build();

$apiResponse = $client->getLocationsApi()->listLocations();

if ($apiResponse->isSuccess()) {
    $listLocationsResponse = $apiResponse->getResult();
} else {
    $errors = $apiResponse->getErrors();
}

// Getting more response information
var_dump($apiResponse->getStatusCode());
var_dump($apiResponse->getHeaders());
```
