README

This repository contains the open source PHP SDK that allows you to access the Product Advertising API from your PHP app.

Copy of Amazon's Provided Code

This is a near identical public copy of Amazon's provided code, as their version is not available through Packagist as of writing.

We have not changed the API in any way, however we did cleanup portions of the code and have updated dependencies. A listing of changes are provided below.

Changes from Amazon

Replaced usage of \GuzzleHttp\Psr7\build_query with \GuzzleHttp\Psr7\Query::build #8
Added Support for Guzzle 7 #6
Removed Deprecation Warnings when using PHP 8 #13
Removed Dynamic Property Creation Warnings when using PHP 8 #13
Updated PHP Minimum Version to PHP 8 #13
CodeSniffed to PSR-2 #13
Updated Dev Dependencies to reflect PHP 8 version requirement #13

Installation

The Product Advertising API PHP SDK can be installed with Composer. The SDK is available via Packagist under the thewirecutter/paapi5-php-sdk package. If Composer is installed globally on your system, you can run the following in the base directory of your project to add the SDK as a dependency:

composer require thewirecutter/paapi5-php-sdk

Usage

Note: This version of the Product Advertising API SDK for PHP requires PHP 5.5 or greater.

Simple example for SearchItems to discover Amazon products with the keyword 'Harry Potter' in Books category:
