PHP Amazon API Development: How to Obtain User Information and Account Permissions

Introduction
Amazon provides a rich set of APIs that allow developers to easily interact with the Amazon platform. Among them, obtaining user information and account permissions is one of the commonly used functions in development. This article will introduce how to use PHP to develop Amazon API to obtain user information and account permissions.

Step 1: Create an Amazon Developer Account
Before you begin, you need to create an Amazon Developer Account. Visit the Amazon Developer Center (https://developer.amazon.com/) and follow the instructions to register a new account. After completing the registration, you will receive a developer key to access the Amazon API.

Step 2: Install PHP SDK
Amazon provides developers with PHP SDK, making communication with Amazon API more convenient. You can get the latest version of PHP SDK from GitHub (https://github.com/amzn/selling-partner-sdk-php) and install it in your project.

Run the following command in the project directory to install the SDK:

composer require amzn/selling-partner-sdk

Step 3: Obtain authentication credentials
When using Amazon API in a PHP project, you need to sign the request for authentication. Using the "getLwaTokensWithScope" method in the SDK, you can easily obtain the user's authorized credentials.

The following is a code example to obtain authentication credentials:

require 'vendor/autoload.php';

use SellingPartnerApiConfiguration;
use SellingPartnerApiApiAuthorizationApi;
use SellingPartnerApiApiException;

$config = new Configuration();
$config->setAccessKey('YOUR_ACCESS_KEY')
    ->setSecretKey('YOUR_SECRET_KEY')
    ->setRegion('na');

$api = new AuthorizationApi($config);
$scope = 'sellingpartnerapi::notifications';
$refreshToken = 'YOUR_REFRESH_TOKEN';

try {
    $result = $api->getLwaTokensWithScope($refreshToken, $scope);
    $access_token = $result['access_token'];
    $refresh_token = $result['refresh_token'];
    // 使用access_token进行API请求
} catch (ApiException $e) {
    echo '错误: ' . $e->getMessage();
}

Step 4: Obtain user information
Once you have obtained the authentication credentials, you can use it to obtain user information. By calling the corresponding API interface, you can obtain the user's name, email address and other important information.

The following is a code example to obtain user information:

require 'vendor/autoload.php';

use SellingPartnerApiConfiguration;
use SellingPartnerApiApiUsersApi;
use SellingPartnerApiApiException;

$config = new Configuration();
$config->setAccessKey('YOUR_ACCESS_KEY')
    ->setSecretKey('YOUR_SECRET_KEY')
    ->setRegion('na')
    ->setAccessToken('YOUR_ACCESS_TOKEN');

$api = new UsersApi($config);

try {
    $result = $api->getUser();
    $user_id = $result['user']['userId'];
    $email = $result['user']['primaryEmail'];
    // 处理获取的用户信息
} catch (ApiException $e) {
    echo '错误: ' . $e->getMessage();
}

Step 5: Obtain account permissions
In addition to user information, you can also obtain the user's account permissions. By calling the corresponding API interface, you can obtain the user's permission settings on the Amazon platform and access restrictions.

The following is a code example to obtain account permissions:

require 'vendor/autoload.php';

use SellingPartnerApiConfiguration;
use SellingPartnerApiApiAuthorizationApi;
use SellingPartnerApiApiException;

$config = new Configuration();
$config->setAccessKey('YOUR_ACCESS_KEY')
    ->setSecretKey('YOUR_SECRET_KEY')
    ->setRegion('na')
    ->setAccessToken('YOUR_ACCESS_TOKEN');

$api = new AuthorizationApi($config);
$resource = '/sellers/{sellerId}/userPermissions';

try {
    $result = $api->getAuthorizationCode($resource);
    $permissions = $result['payload']['grantList'];
    // 处理获取的账户权限信息
} catch (ApiException $e) {
    echo '错误: ' . $e->getMessage();
}

Conclusion
By using PHP and the API provided by Amazon, we can easily obtain user information and account permissions. This article provides some basic code examples that we hope will help you develop your Amazon API more smoothly. Of course, in actual development, you may need to make appropriate adjustments and expansions based on specific needs. I wish you success in using the Amazon API!
