README

PHP client implementation and samples for the paydirekt REST API.

The source code demonstrates how to create valid requests for the paydirekt REST API using PHP.

Requirements

• PHP 5.5 or later
• random_compat (for cryptographically secure pseudo-random bytes)

Dev-Dependencies

• PHP cURL support (for integration tests)
• PHPUnit

Usage

With Composer installed, clone this repository and install with:

composer install

Run the unit and integration tests with:

composer test

The integration tests run against the actual sandbox endpoint.

HMAC Signature

The HMAC signature (to be used in the X-Auth-Code header) can be created using the Hmac.php class.

$randomNonce = Nonce::createRandomNonce();
$signature = Hmac::signature($requestId, $timestamp, $apiKey, $apiSecret, $randomNonce)

API-Key and API-Secret for the your shop are provided via the paydirekt merchant portal. Be aware that there are different credentials for sandbox and production.

Please refer to ObtainTokenIntegrationTest.php for a full example how to build an http request with all header fields and payload.

Security Advice

Do never print sensitive information to log files. The following values should never be logged:

• API-Secret
• OAuth2 Access Token
