$ composer require akamai-open/edgegrid-auth

Download the PHAR file from the releases page and include it inside your code:

include 'akamai-open-edgegrid-auth.phar';

// Library is ready to use

Clone or download

  2. Use the composer autoloader and install the dependencies.

      $ composer install
  3. Include the autoloader.

    require_once 'vendor/autoload.php';

    If you don't use the autoloader, include all the required classes manually in your code.

    require_once 'src/Authentication.php';
    require_once 'src/Authentication/Timestamp.php';
    require_once 'src/Authentication/Nonce.php';
    require_once 'src/Authentication/Exception.php';
    require_once 'src/Authentication/Exception/ConfigException.php';
    require_once 'src/Authentication/Exception/SignerException.php';
    require_once 'src/Authentication/Exception/SignerException/InvalidSignDataException.php';


Once you have installed the library, you can create the header value by calling the appropriate \Akamai\Open\Edgegrid\Authentication::set*() methods.

For example, using it with the built-in streams HTTP client might look like the following:

$auth = \Akamai\Open\EdgeGrid\Authentication::createFromEdgeRcFile('default', '/.edgerc');

$context = array(
  'http' => array(
    'header' => array(
      'Authorization: ' . $auth->createAuthHeader(),
      'Content-Type: application/json'

$context = stream_context_create($context);

$response = json_decode(file_get_contents('https://' . $auth->getHost() . $auth->getPath(), null, $context));
