Setting Configuration

Your Amazon Pay keys are available in your Seller Central account

Setting configuration while instantiating the Client object

<?php
namespace AmazonPay;

require_once 'Client.php';
// or, instead of using require_once, you can use the phar file instead
// include 'amazon-pay.phar';

// PHP Associative array
$config = array(
    'merchant_id' => 'YOUR_MERCHANT_ID',
    'access_key'  => 'YOUR_ACCESS_KEY',
    'secret_key'  => 'YOUR_SECRET_KEY',
    'client_id'   => 'YOUR_LOGIN_WITH_AMAZON_CLIENT_ID',
    'region'      => 'REGION');

// or, instead of setting the array in the code, you can
// initialze the Client by specifying a JSON file
// $config = 'PATH_TO_JSON_FILE';

// Instantiate the client class with the config type
$client = new Client($config);

Testing in Sandbox Mode

The sandbox parameter is defaulted to false if not specified:

<?php
namespace AmazonPay;

$config = array(
    'merchant_id' => 'YOUR_MERCHANT_ID',
    'access_key'  => 'YOUR_ACCESS_KEY',
    'secret_key'  => 'YOUR_SECRET_KEY',
    'client_id'   => 'YOUR_LOGIN_WITH_AMAZON_CLIENT_ID',
    'region'      => 'REGION',
    'sandbox'     => true);

$client = new Client($config);

// Also you can set the sandbox variable in the config() array of the Client class by

$client->setSandbox(true);

Setting Proxy values

Proxy parameters can be set after Instantiating the Client Object with the following setter

$proxy =  array();
$proxy['proxy_user_host'] // Hostname for the proxy
$proxy['proxy_user_port'] // Hostname for the proxy
$proxy['proxy_user_name'] // If your proxy requires a username
$proxy['proxy_user_password'] // If your proxy requires a password

$client->setProxy($proxy);

Making an API Call

Below is an example on how to make the GetOrderReferenceDetails API call:

<?php
namespace AmazonPay;

$requestParameters = array();

// AMAZON_ORDER_REFERENCE_ID is obtained from the Amazon Pay Address/Wallet widgets
// ACCESS_TOKEN is obtained from the GET parameter from the URL.

// Required Parameter
$requestParameters['amazon_order_reference_id'] = 'AMAZON_ORDER_REFERENCE_ID';

// Optional Parameter
$requestParameters['address_consent_token']  = 'ACCESS_TOKEN';
$requestParameters['mws_auth_token']         = 'MWS_AUTH_TOKEN';

$response = $client->getOrderReferenceDetails($requestParameters);

See the API Response section for information on parsing the API response.

Below is an example on how to make the GetMerchantAccountStatus API call:

$requestParameters = array();

// Optional Parameter
$requestParameters['mws_auth_token']         = 'MWS_AUTH_TOKEN';

$response = $client->getMerchantAccountStatus($requestParameters);
echo $response->toXml() . "\n";

// Sample Response
<GetMerchantAccountStatusResponse xmlns="http://mws.amazonservices.com/schema/OffAmazonPayments/2013-01-01">
  <GetMerchantAccountStatusResult>
    <AccountStatus>ACTIVE</AccountStatus>

// Optional Parameter
$requestParameters['mws_auth_token'] = 'MWS_AUTH_TOKEN';
$configArray['page_size']            = "1";

$response = $client->listOrderReference($requestParameters);
echo $response->toXml() . "\n";

// Sample Response

IPN Handling

To receive IPN's successfully you will need an valid SSL on your domain.
You can set up your Notification endpoints by either (a) using the Seller Central Integration Settings page Settings tab, or (b) by using the SetMerchantNotificationConfiguration API call.
IpnHandler.php class handles verification of the source and the data of the IPN

Add the below code into any file and set the URL to the file location in Merchant/Integrator URL by accessing Integration Settings page in the Settings tab.

<?php
namespace AmazonPay;

require_once 'IpnHandler.php';

// Get the IPN headers and Message body
$headers = getallheaders();
$body = file_get_contents('php://input');

// Create an object($ipnHandler) of the IpnHandler class
$ipnHandler = new IpnHandler($headers, $body);

See the IPN Response section for information on parsing the IPN response.

Setting notification endpoints using SetMerchantNotificationConfiguration API

$client = new AmazonPay\Client($config);

// possible array values: ALL, ORDER_REFERENCE, PAYMENT_AUTHORIZE, PAYMENT_CAPTURE, PAYMENT_REFUND, BILLING_AGREEMENT, CHARGEBACK_DETAILED
$notificationConfiguration['https://dev.null/ipn/onetime'] = array('ORDER_REFERENCE', 'PAYMENT_AUTHORIZE', 'PAYMENT_CAPTURE');
$notificationConfiguration['https://dev.null/ipn/recurring'] = array('BILLING_AGREEMENT');
$notificationConfiguration['https://dev.null/ipn/refunds'] = array('PAYMENT_REFUND', 'CHARGEBACK_DETAILED');
$requestParameters['notification_configuration_list'] = $notificationConfiguration;

// or, if you prefer all IPNs come to the same endpoint, do this one-liner instead:
// $requestParameters['notification_configuration_list'] = array('https://dev.null/ipn' => array('ALL'));

// if you are calling on behalf of another merhcant using delegated access, be sure to set the merchant ID and auth token:
// $requestParameters['merchant_id'] = 'THE_MERCHANT_ID';
// $requestParameters['mws_auth_token'] = 'THE_MWS_AUTH_TOKEN';

$response = $client->setMerchantNotificationConfiguration($requestParameters);
if ($response->toArray()['ResponseStatus'] !== '200') {
    print "error occured calling API";
}

// to troubleshoot, you can call GetMerchantNotificationConfiguration to view current IPN settings
$response = $client->getMerchantNotificationConfiguration($requestParameters);
print $response->toXml();

Convenience Methods

Charge Method

The charge method combines the following API calls:

Standard Payments / Recurring Payments

SetOrderReferenceDetails / SetBillingAgreementDetails
ConfirmOrderReference / ConfirmBillingAgreement
Authorize / AuthorizeOnBillingAgreement

For Standard payments the first charge call will make the SetOrderReferenceDetails, ConfirmOrderReference, Authorize API calls. Subsequent call to charge method for the same Order Reference ID will make the call only to Authorize.

For Recurring payments the first charge call will make the SetBillingAgreementDetails, ConfirmBillingAgreement, AuthorizeOnBillingAgreement API calls. Subsequent call to charge method for the same Billing Agreement ID will make the call only to AuthorizeOnBillingAgreement.

Capture Now can be set to true for digital goods . For Physical goods it's highly recommended to set the Capture Now to false and the amount captured by making the capture API call after the shipment is complete.

$config = array(
    'client_id' => 'YOUR_LWA_CLIENT_ID',
    'region'    => 'REGION');

$client = new Client($config);

// Client ID can also be set using the setter function setClientId($client_id)
$client->setClientId(‘YOUR_LWA_CLIENT_ID’);

// Get the Access Token from the URL
$access_token = 'ACCESS_TOKEN';
// Calling the function getUserInfo with the access token parameter returns object
$userInfo = $client->getUserInfo($access_token);

// Buyer name
$userInfo['name'];
// Buyer Email
$userInfo['email'];
// Buyer User Id
$userInfo['user_id'];

// Returns an object($response) of the class ResponseParser.php
$response = $client->getOrderReferenceDetails($requestParameters);

// XML response
$response->toXml();

// Associative array response
$response->toArray();

// JSON response
$response->toJson();

IPN Response
