SellingPartnerSDK - Facade for all SDK's

Authorization

In order to start using SP API you need to first register as a Developer and create application. Whole process is described in Amazon Official Guides.

Amazon recommends to use Role IAM when creating application however this requires and additional API request in order to obtain access token. It's easier to use User IAM and just make sure that the user has following Inline Policy

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "execute-api:Invoke",
            "Resource": "arn:aws:execute-api:*:*:*"
        }
    ]
}

IAM User

Example of changing refresh token into access token.

<?php

use MehrIt\AmazonSellingPartner\OAuth;
use MehrIt\AmazonSellingPartner\Configuration;
use MehrIt\AmazonSellingPartner\HttpFactory;
use Buzz\Client\Curl;
use Nyholm\Psr7\Factory\Psr17Factory;

$factory = new Psr17Factory();
$client = new Curl($factory);

$oauth = new OAuth(
    $client,
    $httpFactory = new HttpFactory($factory, $factory),
    $config = Configuration::forIAMUser(
        'lwaClientId',
        'lwaClientIdSecret',
        'awsAccessKey',
        'awsSecretKey'
    )
);

$accessToken = $oauth->exchangeRefreshToken('seller_oauth_refresh_token');

IAM Role

<?php

use MehrIt\AmazonSellingPartner\OAuth;
use MehrIt\AmazonSellingPartner\Configuration;
use MehrIt\AmazonSellingPartner\HttpFactory;
use Buzz\Client\Curl;
use Nyholm\Psr7\Factory\Psr17Factory;

$factory = new Psr17Factory();
$client = new Curl($factory);

$sts = new STSClient(
    $client,
    $requestFactory = $factory,
    $streamFactory = $factory
);

$oauth = new OAuth(
    $client,
    $httpFactory = new HttpFactory($requestFactory, $streamFactory),
    $config = Configuration::forIAMRole(
        'lwaClientID',
        'lwaClientID',
        $sts->assumeRole(
            'awsAccessKey',
            'awsSecretKey',
            'arn:aws:iam::.........'
        )
    )
);

$accessToken = $oauth->exchangeRefreshToken('seller_oauth_refresh_token');

Development

99% of code in this library is auto generated from Amazon Selling Partner API Models using OpenAPI Generator tool. Output is later automatically upgraded by RectorPHP to PHP 7.4 version and finally coding standards are also automatically unified by PHP CS Fixer.

Requirements:

In oder to regenerate code (for example when API definitions change), execute following code:

composer generate

Examples

<?php

use MehrIt\AmazonSellingPartner\Marketplace;
use MehrIt\AmazonSellingPartner\Regions;
use MehrIt\AmazonSellingPartner\SellingPartnerSDK;
use Buzz\Client\Curl;
use MehrIt\AmazonSellingPartner\Exception\ApiException;
use MehrIt\AmazonSellingPartner\Configuration;
use Monolog\Handler\StreamHandler;
use Monolog\Logger;
use Nyholm\Psr7\Factory\Psr17Factory;

require_once __DIR__ . '/vendor/autoload.php';

$factory = new Psr17Factory();
$client = new Curl($factory);

$configuration = Configuration::forIAMUser(
    'lwaClientId',
    'lwaClientIdSecret',
    'awsAccessKey',
    'awsSecretKey'
);

$logger = new Logger('name');
$logger->pushHandler(new StreamHandler(__DIR__ . '/sp-api-php.log', Logger::DEBUG));

$sdk = SellingPartnerSDK::create($client, $factory, $factory, $configuration, $logger);

$accessToken = $sdk->oAuth()->exchangeRefreshToken('seller_oauth_refresh_token');

try {
    $item = $sdk->catalogItem()->getCatalogItem(
        $accessToken,
        Regions::NORTH_AMERICA,
        $marketplaceId = Marketplace::US()->id(),
        $asin = 'B07W13KJZC'
    );
    dump($item);
} catch (ApiException $exception) {
    dump($exception->getMessage());
}

Logging

Default log level is set up to DEBUG, but it can be changed in configuration to any other level for all operations in all APIs or only for given operation in given API.

$configuration->setDefaultLogLevel(\Psr\Log\LogLevel::INFO);

Specific API's or only given operations can be also excluded from logging (for example APIs with PII or sensitive data).

$configuration->setLogLevel(CatalogItemSDK::API_NAME, CatalogItemSDK::OPERATION_GETCATALOGITEM, LogLevel::INFO);
$configuration->setSkipLogging(TokensSDK::API_NAME);
$configuration->setSkipLogging(AuthorizationSDK::API_NAME, AuthorizationSDK::OPERATION_GETAUTHORIZATIONCODE);

Finally, you can also ignore specific headers when logging http request/response. By default, configuration is set to ignore following sensitive authorization headers:

'authorization',
'x-amz-access-token',
'x-amz-security-token',
'proxy-authorization',
'www-authenticate',
'proxy-authenticate',

you can also add your own ignored headers:

$configuration->loggingAddSkippedHeader('some-sensitive-key');

Extensions

Each SDK allows you to register custom extensions executed before and after sending API requests.

<?php 

$configuration->registerExtension(new class implements \MehrIt\AmazonSellingPartner\Extension {
    public function preRequest(string $api, string $operation, RequestInterface $request): void
    {
        echo "pre: " . $api . "::" . $operation . " " . $request->getUri() . "\n";
    }

    public function postRequest(string $api, string $operation, RequestInterface $request, ResponseInterface $response): void
    {
        echo "post: " . $api . "::" . $operation . " " . $request->getUri() . " " 
            . $response->getStatusCode() . " rate limit: " . implode(' ', $response->getHeader('x-amzn-RateLimit-Limit')) . "\n";
    }
});
