README

Lightweight PHP 8.3 HTTP client for the Amazon Advertising API. Covers OAuth 2.0 authentication, typed request/response models, automatic token refresh, retry with exponential backoff, and optional access-token caching.

Features

• OAuth 2.0 — authorization code exchange, token refresh, pluggable token cache (FileTokenCache included)
• Typed models — enums, DTOs with getters/setters, toArray() / fromArray() serialization
• Full endpoint coverage — Campaigns, Ad Groups, Ads, Targets, Ad Associations, Ad Extensions, Advertising Deals, Brand Stores, Commitments, Recommendations, and more
• Retry logic — automatic retry with exponential backoff on 429 / 504; token refresh and retry on 401
• API exceptions — AmazonAdsApiException with HTTP status code, response error code, and message
• Multi-region — NA, EU, FE base URLs

Requirements

• PHP ≥ 8.3
• ext-curl
• ext-json

Installation

composer require creatissimo/amazon-ads-api

Quick start

use Creatissimo\AmazonAdsApi\Auth\FileTokenCache;
use Creatissimo\AmazonAdsApi\Auth\OAuthClient;
use Creatissimo\AmazonAdsApi\Http\HttpClient;
use Creatissimo\AmazonAdsApi\Api\CampaignsApi;
use Creatissimo\AmazonAdsApi\Model\AdProduct;
use Creatissimo\AmazonAdsApi\Model\CampaignAdProductFilter;
use Creatissimo\AmazonAdsApi\Model\QueryCampaignRequest;

$oauth = new OAuthClient(
    clientId: 'amzn1.application-oa2-client.xxx',
    clientSecret: 'your-secret',
    redirectUri: 'https://your-app.com/callback',
    tokenCache: new FileTokenCache('/tmp/amazon-ads-tokens'),
);

$oauth->setTokens(
    accessToken: 'placeholder',
    refreshToken: 'Atzr|...',
    expiresAt: 0,
);

$http = new HttpClient(
    oauthClient: $oauth,
    clientId: 'amzn1.application-oa2-client.xxx',
    baseUrl: HttpClient::REGION_EU,
    profileId: '123456789',
);

$campaigns = new CampaignsApi($http);

$response = $campaigns->query(new QueryCampaignRequest(
    adProductFilter: new CampaignAdProductFilter(
        include: [AdProduct::SPONSORED_PRODUCTS],
    ),
    maxResults: 10,
));

foreach ($response->getCampaigns() as $campaign) {
    echo $campaign->getName() . PHP_EOL;
}

Token caching

Pass any TokenCacheInterface implementation to OAuthClient. A file-based cache is included:

$cache = new FileTokenCache(__DIR__ . '/var/cache/tokens');

$oauth = new OAuthClient(
    clientId: '...',
    clientSecret: '...',
    redirectUri: '...',
    tokenCache: $cache,
);

Implement TokenCacheInterface for Redis, Memcached, database, or PSR-16 adapters.

Error handling

All API methods throw AmazonAdsApiException on non-success responses:

use Creatissimo\AmazonAdsApi\Http\AmazonAdsApiException;

try {
    $campaigns->query($request);
} catch (AmazonAdsApiException $e) {
    $e->getHttpStatusCode();  // 400, 401, 403, ...
    $e->getResponseCode();    // "INVALID_ARGUMENT", ...
    $e->getResponseMessage(); // "Missing required field"
    $e->getResponseBody();    // full response array
}

Retry behaviour

The HTTP client automatically retries on 429 (Too Many Requests) and 504 (Gateway Timeout) with exponential backoff. On 401 (Unauthorized) it refreshes the access token once and retries. Both maxRetries and retryBaseDelay are configurable:

$http = new HttpClient(
    oauthClient: $oauth,
    clientId: '...',
    maxRetries: 5,
    retryBaseDelay: 2.0, // seconds; delays: 2, 4, 8, 16, 32
);
