Akamai EdgeGrid Authentication for PHP

This library requires PHP 8+ and implements the Akamai EdgeGrid Authentication scheme on top of Guzzle as both a drop-in replacement client and middleware.


To install, use composer:

$ composer require akamai-open/edgegrid-client

Alternative installation method

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


The Akamai\Open\EdgeGrid\Client extends \GuzzleHttp\Client as a drop-in replacement. It works transparently to sign API requests without changing other ways you use Guzzle.

To use the client, call \Akamai\Open\EdgeGrid\Client->setAuth() or provide an instance of \Akamai\Open\EdgeGrid\Authentication to the constructor prior to making a request to an API.

$client = new Akamai\Open\EdgeGrid\Client([
  'base_uri' => 'https://akab-h05tnam3wl42son7nktnlnnx-kbob3i3v.luna.akamaiapis.net'

$client->setAuth($client_token, $client_secret, $access_token);

// use $client just as you would \Guzzle\Http\Client
$response = $client->get('/identity-management/v3/user-profile');


To generate your credentials, see Create authentication credentials.

We recommend using a local .edgerc authentication file. Place your credentials under a heading of [default] at your local home directory or the home directory of a web-server user.

client_secret = C113nt53KR3TN6N90yVuAgICxIRwsObLi0E67/N8eRN=
host = akab-h05tnam3wl42son7nktnlnnx-kbob3i3v.luna.akamaiapis.net
access_token = akab-acc35t0k3nodujqunph3w7hzp7-gtm6ij
client_token = akab-c113ntt0k3n4qtari252bfxxbsl-yvsdj

You can call your .edgerc file one of two ways:

  • Use the factory method \Akamai\Open\EdgeGrid\Client::createFromEdgeRcFile().

    $client = \Akamai\Open\EdgeGrid\Client::createFromEdgeRcFile();
    // use $client just as you would \Guzzle\Http\Client
    $response = $client->get('/identity-management/v3/user-profile');
  • Specify a credentials section and/or .edgerc location:

    $client = \Akamai\Open\EdgeGrid\Client::createFromEdgeRcFile('example', '../config/.edgerc');
    // use $client just as you would \Guzzle\Http\Client
    $response = $client->get('/identity-management/v3/user-profile');

Command line interface

This library provides a command line interface (CLI) with a limited set of capabilities that mimic httpie.


Install the CLI with composer vendor/bin/http or execute the PHAR file.

# Composer installed
$ ./vendor/bin/http --help

# For Windows
> php ./vendor/bin/http --help

# PHAR download
php akamai-open-edgegrid-client.phar --help


You can set authentication and specify an HTTP method (case insensitive), its headers, and any JSON body fields.

Note: Our CLI shows all HTTP and body data. JSON is formated.

Argument Description
--auth-type={edgegrid,basic,digest} Set the authentication type. The default is none.
--auth user: or --a user: Set the .edgerc section to use. Unlike httpie-edgegrid, the colon (:) is optional.
Header-Name:value Headers and values are colon (:) separated.
jsonKey=value Sends {"jsonKey": "value"} in the POST or PUT body. This will also automatically set the Content-Type and Accept headers to application/json.
jsonKey:=[1,2,3] Allows you to specify raw JSON data, sending {"jsonKey": [1, 2, 3]} in the body.


  • You cannot send multipart/mime (file upload) data.
  • Client certs are not supported.
  • Server certs cannot be verified.
  • Output cannot be customized.
  • Responses are not syntax highlighted.

Guzzle Middleware

This package provides three different middleware handlers you can add transparently when using the Client, to a standard \GuzzleHttp\Client or as a handler.

  • The \Akamai\Open\EdgeGrid\Handler\Authentication for transparent API request signing.
  • The \Akamai\Open\EdgeGrid\Handler\Verbose for output (or log) responses.
  • The \Akamai\Open\EdgeGrid\Handler\Debug for output (or log) errors.

Transparent Use

Handler Call
Authentication Client->setAuthentication() or pass in an instance of \Akamai\EdgeGrid\Authentication to Client->__construct().
Verbose Client->setInstanceVerbose() or Client::setVerbose() passing in on of `true
Debug Client->setInstanceDebug(), Client::setDebug(), or set the debug config option with `true


Handler Example
// Create the Authentication Handler
$auth = \Akamai\Open\EdgeGrid\Handler\Authentication::createFromEdgeRcFile();
// or:
$auth = new \Akamai\Open\EdgeGrid\Handler\Authentication;
$auth->setAuth($client_token, $client_secret, $access_token);
// Create the handler stack
$handlerStack = \GuzzleHttp\HandlerStack::create();
// Add the Auth handler to the stack
// Add the handler to a regular \GuzzleHttp\Client
$guzzle = new \GuzzleHttp\Client([
"handler" => $handlerStack

// Create the handler stack
$handlerStack = HandlerStack::create();

// Add the Auth handler to the stack
$handlerStack->push(new \Akamai\Open\EdgeGrid\Handler\Verbose());

// Add the handler to a regular \GuzzleHttp\Client
$guzzle = new \GuzzleHttp\Client([
    "handler" => $handlerStack
// Create the handler stack
$handlerStack = HandlerStack::create();

// Add the Auth handler to the stack
$handlerStack->push(new \Akamai\Open\EdgeGrid\Handler\Debug());

// Add the handler to a regular \GuzzleHttp\Client
$guzzle = new \GuzzleHttp\Client([
    "handler" => $handlerStack
