Upgrading v1.x.x -> v2.x.x -> v3.x.x

V2 introduced PHP >=7.4 support (8.0 is also supported). All you need to do is change version in composer.json file. All resources and methods are the same as in V1, so you don't need to update your code.

V1 will not be maintained anymore, so please upgrade as fast as you can.

Installation

Just use composer:

composer require imper86/php-allegro-api

HTTPlug note

This lib uses HTTPlug so it doesn't depend on any http client. In order to use this lib you must have some PSR-18 http client and PSR-17 http factories. If you don't know which one you shoud install you can require these:

composer require php-http/guzzle6-adapter http-interop/http-factory-guzzle

Authentication & usage

Library has a bunch of mechanisms that allows you to forget about tokens, expirations etc. But in order to start using it you must authorize user using Oauth flow.

use Imper86\PhpAllegroApi\AllegroApi;
use Imper86\PhpAllegroApi\Model\Credentials;
use Imper86\PhpAllegroApi\Oauth\FileTokenRepository;
use Imper86\PhpAllegroApi\Plugin\AuthenticationPlugin;

// first, create Credentials object
$credentials = new Credentials(
    'your-client-id',
    'your-client-secret',
    'your-redirect-uri',
    true //is sandbox
);

// create api client
$api = new AllegroApi($credentials);

// get the authorization URL, and redirect your user:
$state = 'your-random-secret-state';
header(sprintf('Location: %s', $api->oauth()->getAuthorizationUri(true, $state)));

/*
 * after successfull authorization, user will be refirected to your
 * redirect_uri with state and code as query parameters
 */

// verify the state and fetch token
if ($state !== $_GET['state'] ?? null) {
    throw new Exception('CSRF?!');
}

$token = $api->oauth()->fetchTokenWithCode($_GET['code']);

// create TokenRepository object
$tokenRepository = new FileTokenRepository(
    $token->getUserId(), 
    __DIR__ . '/tokens'
);
$tokenRepository->save($token);

/*
 * You can invent your own TokenRepository, just implement
 * Imper86\PhpAllegroApi\Oauth\TokenRepositoryInterface
 * You can use your DB, Redis, or anything you want.
 */

// now you can add AuthenticationPlugin, which will take care
// of maintaining your tokens

$api->addPlugin(new AuthenticationPlugin($tokenRepository, $api->oauth()));

// * note: of course you can use your own plugin, or AuthenticationPlugin from HTTPlug library

// from now you can use these methods on AllegroApi object:
$api->account()->(...);
$api->afterSalesServiceConditions()->(...);
$api->bidding()->(...);
$api->billing()->(...);
$api->me()->(...);
$api->offers()->(...);
$api->order()->(...);
$api->payments()->(...);
$api->pointsOfService()->(...);
$api->pricing()->(...);
$api->sale()->(...);
$api->users()->(...);

// fast example:
var_dump($api->sale()->offers()->tags()->get('123456'));

If you use IDE with typehinting such as PHPStorm, you'll easily figure it out. If not, please take a look in Resource directory

Device Flow

use Imper86\PhpAllegroApi\AllegroApi;
use Imper86\PhpAllegroApi\Model\Credentials;
use Imper86\PhpAllegroApi\Oauth\FileTokenRepository;
use Imper86\PhpAllegroApi\Plugin\AuthenticationPlugin;

// first, create Credentials object
$credentials = new Credentials(
    'your-client-id',
    'your-client-secret',
    'your-redirect-uri',
    true //is sandbox
);

// create api client
$api = new AllegroApi($credentials);

// Create authorization session
$session = $api->oauth()->getDeviceCode();

// Provide device code and/or url to user
echo 'Please visit: ' . $session->getVerificationUriComplete();

// Poll for authorization result
$interval = $session->getInterval();
$token = false;
do {
    sleep($interval);
    $device_code = $session->getDeviceCode();
    try{
        $token = $api->oauth()->fetchTokenWithDeviceCode($device_code);
    } catch (AuthorizationPendingException) {
        continue;
    } catch (SlowDownException) {
        $interval++;
        continue;
    }
} while ($token == false);

// create TokenRepository object
$tokenRepository = new FileTokenRepository(
    $token->getUserId(), 
    __DIR__ . '/tokens'
);
$tokenRepository->save($token);
