SPAPI

spapi-php is a http client for Amazon's Selling Partner API

Author: Lyubomir Slavilov

Before you start

Spapi is released as Composer package double-break/spapi-php with no warranties or promises.

There are couple classes (such as Signer, Credentials) which are essential for the API calls to work. Most of the issues will live here.

All of the actual API clients are autogenerated and given the disclaimer above - not heavily tested.

Requirements

php 7.3 (never tested on lower version)
composer
a lot of time reading Amazon SP API documentation

Install and update

Now you are ready to do

composer require double-break/spapi-php

composer update double-break/spapi-php

Examples

Simple use

<?php
  include __DIR__ . '/vendor/autoload.php';

  /** The Setup **/

  $config = [
    //Guzzle configuration
    'http' => [
      'verify' => false,    //<--- NOT SAFE FOR PRODUCTION
      'debug' => true       //<--- NOT SAFE FOR PRODUCTION
    ],

    //LWA: Keys needed to obtain access token from Login With Amazon Service
    'refresh_token' => '<YOUR-REFRESH-TOKEN>',
    'client_id' => '<CLINET-ID-IN-SELLER-CONSOLE>',
    'client_secret' => '<CLIENT_SECRET>',

    //STS: Keys of the IAM role which are needed to generate Secure Session
    // (a.k.a Secure token) for accessing and assuming the IAM role
    'access_key' => '<STS-ACCESS_KEY>',
    'secret_key' => '<STS-SECRET-KEY>',
    'role_arn' => '<ROLE-ARN>' ,

    //API: Actual configuration related to the SP API :)
    'region' => 'eu-west-1',
    'host' => 'sellingpartnerapi-eu.amazon.com'
  ];

  //Create token storage which will store the temporary tokens
  $tokenStorage = new DoubleBreak\Spapi\SimpleTokenStorage('./aws-tokens');

  //Create the request signer which will be automatically used to sign all of the
  //requests to the API
  $signer = new DoubleBreak\Spapi\Signer();

  //Create Credentials service and call getCredentials() to obtain
  //all the tokens needed under the hood

  $credentials = new DoubleBreak\Spapi\Credentials($tokenStorage, $signer, $config);
  $cred = $credentials->getCredentials();

  /** The application logic implementation **/

  //Create SP API Catalog client and execute one ot its REST methods.
  $catalogClient = new DoubleBreak\Spapi\Api\CatalogItems($cred, $config);

  //Check the catalog info for B074Z9QH5F ASIN
  $result = $catalogClient->getCatalogItem('B074Z9QH5F', [
      'marketplaceIds' => 'A1PA6795UKMFR9',
  ]);

  print_r($result);

Feed API usage

For Feed API, user can follow Feeds API Use Case Guide.

And in this guide for step 2. Encrypt and upload the feed data: user can use below example:

<?php

// content type of the feed data to be uploaded.
$contentType = 'text/xml; charset=UTF-8';

// create feed document
$feedClient = new \DoubleBreak\Spapi\Api\Feeds($cred, $config);
$response = $feedClient->createFeedDocument(["contentType" => $contentType]);
$payload = $response['payload'];

$feedContentFilePath = './testFeedDoc.xml';

$result = (new \DoubleBreak\Spapi\Helper\Feeder())->uploadFeedDocument($payload,$contentType,$feedContentFilePath);
print_r($result);

And for Step 6. Download and decrypt the feed processing report: user can use below example:

<?php
$feedClient = new \DoubleBreak\Spapi\Api\Feeds($cred, $config);

// $resultFeedDocumentId: from response of getFeed() function.
$resultFeedDocumentId = 'amzn1.tortuga.3.ed4cd0d8-447b-4c22-96b5-52da8ace1207.T3YUVYPGKE9BMY';
$response = $feedClient->getFeedDocument($resultFeedDocumentId);
$payload = $response['payload'];

$result = (new \DoubleBreak\Spapi\Helper\Feeder())->downloadFeedProcessingReport($payload);
print_r($result);

Debugging responses

<?php
  //configuration and initialization here

  $catalogClinet = new DoubleBreak\Spapi\Api\Catalog($cred, $config);
  try {
    $result = $catalogClinet->getCatalogItem('B074Z9QH5F', [
      'MarketplaceId' => 'A1PA6795UKMFR9',
    ])['payload'];
    //do your business here
  } catch (\GuzzleHttp\Exception\ClientException $e) {
    $httpCode = $e->getResponse()->getStatusCode();
    $errorBody =  $e->getResponse()->getBody();

    echo "Amazon SP API responded with HTTP {$httpCode}\n {$errorBody}";

  } catch(\Exception $e) {
    echo "Unexpected exception: " . $e->getMessage();
  }

Accessing response headers

📝Accessing headers by using client's getLastHttpResponse() is available since v1.0.5

<?php
  //configuration and initialization here

  //Create SP API Catalog client and execute one ot its REST methds.
  $catalogClinet = new DoubleBreak\Spapi\Api\Catalog($cred, $config);

  //Check the catalog info for B074Z9QH5F ASIN
  $result = $catalogClinet->getCatalogItem('B074Z9QH5F', [
    'MarketplaceId' => 'A1PA6795UKMFR9',
  ])['payload'];

  $headers = $catalogClinet->getLastHttpResponse()->getHeaders();
  foreach ($headers as $headerName => $values) {
    echo "{$headerName}: " . implode(','. $values);
  }
