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.

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

• PHP cURL support (for integration tests)
• PHPUnit

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.

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.

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

• API-Secret
• OAuth2 Access Token
