Migrate to the Square PHP SDK

Follow the instructions below to migrate your apps from the deprecated square/connect sdk to the new library.

You need to update your app to use the Square PHP SDK instead of the Connect PHP SDK The Square PHP SDK uses the square/square identifier.

1. On the command line, run:

$ php composer.phar require square/square

-or-

2. Update your composer.json:

"require": {
    ...
    "square/square": "^5.0.0",
    ...
}

Update your code

1. Change all instances of use SquareConnect\... to use Square\....
2. Replace SquareConnect models with the new Square equivalents
3. Update client instantiation to follow the method outlined below.
4. Update code for accessing response data to follow the method outlined below.
5. Check $apiResponse->isSuccess() or $apiResponse->isError() to determine if the call was a success.

To simplify your code, we also recommend that you use method chaining to access APIs instead of explicitly instantiating multiple clients.

Client instantiation

Connect SDK

require 'vendor/autoload.php';

use SquareConnect\Configuration;
use SquareConnect\ApiClient;

$access_token = 'YOUR_ACCESS_TOKEN';
# setup authorization
$api_config = new Configuration();
$api_config->setHost("https://connect.squareup.com");
$api_config->setAccessToken($access_token);
$api_client = new ApiClient($api_config);

Square SDK

require 'vendor/autoload.php';

use Square\SquareClient;
use Square\Environment;

// Initialize the Square client.
$api_client = new SquareClient([
  'accessToken' => "YOUR_ACCESS_TOKEN",
  'environment' => Environment::SANDBOX
]); // In production, the environment arg is 'production'

Example code migration

As a specific example, consider the following code for creating a new payment from the following nonce:

# Fail if the card form didn't send a value for `nonce` to the server
$nonce = $_POST['nonce'];
if (is_null($nonce)) {
  echo "Invalid card data";
  http_response_code(422);
  return;
}

With the deprecated square/connect library, this is how you instantiate a client for the Payments API, format the request, and call the endpoint:

use SquareConnect\Api\PaymentsApi;
use SquareConnect\ApiException;

$payments_api = new PaymentsApi($api_client);
$request_body = array (
  "source_id" => $nonce,
  "amount_money" => array (
    "amount" => 100,
    "currency" => "USD"
  ),
  "idempotency_key" => uniqid()
);
try {
  $result = $payments_api->createPayment($request_body);
  echo "<pre>";
  print_r($result);
  echo "</pre>";
} catch (ApiException $e) {
  echo "Caught exception!<br/>";
  print_r("<strong>Response body:</strong><br/>");
  echo "<pre>"; var_dump($e->getResponseBody()); echo "</pre>";
  echo "<br/><strong>Response headers:</strong><br/>";
  echo "<pre>"; var_dump($e->getResponseHeaders()); echo "</pre>";
}

Now consider equivalent code using the new square/square library:

require 'vendor/autoload.php';

use Square\Environment;
use Square\Exceptions\ApiException;
use Square\SquareClient;
use Square\Models\CreatePaymentRequest;
use Square\Models\Money;

$payments_api = $api_client->getPaymentsApi();

$money = new Money();
$money->setAmount(100);
$money->setCurrency('USD');
$create_payment_request = new CreatePaymentRequest($nonce, uniqid(), $money);
try {
  $response = $payments_api->createPayment($create_payment_request);
  if ($response->isError()) {
    echo 'Api response has Errors';
    $errors = $response->getErrors();
    exit();
  }
  echo '<pre>';
  print_r($response);
  echo '</pre>';
} catch (ApiException $e) {
  echo 'Caught exception!<br/>';
  exit();
}

That's it!
