What is Amazon Selling Partner API

SP-API is the next-generation API functionality suite for sellers and their agents to sell their products on the Amazon marketplace efficiently. Amazon Marketplace Web Services (Amazon MWS) APIs preceded SP-APIs and have been utilized extensively for over ten years. Amazon states in their documentation that the SP-API is the future and that SP APIs will receive any new updates and enhancements. However, one can expect a transition period from MWS to SP-API while the new system is stabilized and offers parity with the existing MWS APIs.

    'role_arn' => '', // AWS IAM Role ARN for example: arn:aws:iam::123456789:role/Your-Role-Name
];

2. Use refresh_token to exchange access_token

$oAuth = new \AmazonSellingPartnerAPI\OAuth($auth['client_id'], $auth['client_secret']);
$auth['access_token'] = $oAuth->getAccessToken($auth['refresh_token'])->access_token;

$sign = new \AmazonSellingPartnerAPI\Signature\V4Signature();

4. Fetch role info

$assumedRole = new \AmazonSellingPartnerAPI\AssumeRole($auth['region'], $auth['access_key'], $auth['secret_key'], $sign);
$credentials = $assumedRole->assume($auth['role_arn']);
$auth['access_key'] = $credentials['AccessKeyId'];
$auth['secret_key'] = $credentials['SecretAccessKey'];
$auth['session_token'] = $credentials['SessionToken'];
