The Braintree PHP library provides integration access to the Braintree Gateway.

The Payment Card Industry (PCI) Council has mandated that early versions of TLS be retired from service. All organizations that handle credit card information are required to comply with this standard. As part of this obligation, Braintree is updating its services to require TLS 1.2 for all HTTPS connections. Braintree will also require HTTP/1.1 for all connections. Please see our technical documentation for more information.

PHP version >= 5.4.0 is required.

The following PHP extensions are required:

• curl
• dom
• hash
• openssl
• xmlwriter

<?php

require_once 'PATH_TO_BRAINTREE/lib/Braintree.php';

Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('your_merchant_id');
Braintree_Configuration::publicKey('your_public_key');
Braintree_Configuration::privateKey('your_private_key');

$result = Braintree_Transaction::sale([
    'amount' => '1000.00',
    'paymentMethodNonce' => 'nonceFromTheClient',
    'options' => [ 'submitForSettlement' => true ]
]);

if ($result->success) {
    print_r("success!: " . $result->transaction->id);
} else if ($result->transaction) {
    print_r("Error processing transaction:");
    print_r("\n  code: " . $result->transaction->processorResponseCode);
    print_r("\n  text: " . $result->transaction->processorResponseText);
} else {
    print_r("Validation errors: \n");
    print_r($result->errors->deepAll());
}

Both PSR-0 and PSR-4 namespacing are supported. If you are using composer with --classmap-authoritative or
--optimize-autoloader enabled, you'll have to reference classes using PSR-4 namespacing:

Braintree\Configuration::environment('sandbox');
Braintree\Configuration::merchantId('your_merchant_id');
Braintree\Configuration::publicKey('your_public_key');
Braintree\Configuration::privateKey('your_private_key');

The Braintree PHP library will run on HHVM >= 3.4.2.

Version 2.40.0 is compatible with PHP 5.2 and 5.3. You can find it on our releases page.

• Official documentation

The unit specs can be run by anyone on any system, but the integration specs are meant to be run against a local development server of our gateway code. These integration specs are not meant for public consumption and will likely fail if run on your system. To run unit tests use rake: rake test:unit.

The benefit of the rake tasks is that testing covers default hhvm and php interpreters. However, if you want to run tests manually simply use the following command:

phpunit tests/unit/
