Access Amazon Marketplace Data in PHP through Connect Cloud

Connect to Amazon Marketplace through the standard MySQL libraries in PHP.

You can use CData Connect Cloud to access Amazon Marketplace data from MySQL clients, without needing to perform an ETL or cache data. Follow the steps below to create a virtual MySQL database for Amazon Marketplace and connect to Amazon Marketplace data in real time through PHP's standard MySQL interfaces, mysqli and PDO_MySQL.

CData Connect Cloud provides a pure MySQL, cloud-to-cloud interface for Amazon Marketplace, allowing you to easily query live Amazon Marketplace data in PHP — without replicating the data to a natively supported database. As you query data in PHP, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc) directly to Amazon Marketplace, leveraging server-side processing to quickly return Amazon Marketplace data.

Create a Virtual MySQL Database for Amazon Marketplace Data

CData Connect Cloud uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Connect Cloud and click Databases.
  2. Select "Amazon Marketplace" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Amazon Marketplace.

    To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Amazon Marketplace data from any MySQL client.

Connect in PHP

The following examples show how to use object-oriented interfaces to connect and execute queries. Initialize the connection object with the following parameters to connect to the virtual MySQL database:

  • Host: Specify the remote host location where the service is running. In this case "myinstance.cdatacloud.net" is used for the remote host setting since the service is running on the local machine.
  • Username: Specify the username for a user you authorized in Connect Cloud.
  • Password: Specify the password for the authorized user account.
  • Database Name: Specify the name of the virtual database you created for Amazon Marketplace.
  • Port: Specify the port the service is running on, port 3306 in this example.

mysqli

<?php
$mysqli = mysqli_init();

$mysqli->ssl_set("C:/certs/cloudclient.key",
                 "C:/certs/cloudclient.pem",
                 "C:/certs/myCA.pem",
                 NULL,NULL);

$mysqli->real_connect("mysintance.cdatacloud.net", "admin", "mypassword", "amazonmarketplacedb",3306,NULL,MYSQLI_CLIENT_SSL_DONT_VERIFY_SERVER_CERT);
?>

PDO

<?php
$pdo = new PDO('mysql:host=myinstance.cdatacloud.net;dbname=amazonmarketplacedb;port=3306;','admin', 'mypassword', array(
    PDO::MYSQL_ATTR_SSL_KEY                => 'C:/certs/cloudclient.key',
    PDO::MYSQL_ATTR_SSL_CERT               => 'C:/certs/cloudclient.pem',
    PDO::MYSQL_ATTR_SSL_CA                 => 'C:/certs/myCA.pem',
    PDO::MYSQL_ATTR_SSL_VERIFY_SERVER_CERT => false
    )
);
?>

Query in PHP

With the connection established, you can then access tables. The following steps walk through the example:

  1. Query the table; for example, Orders. The results will be stored as an associative array in the $result object.
  2. Iterate over each row and column, printing the values to display in the PHP page.
  3. Close the connection.

mysqli

$result = $mysqli->query("SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True");
while($row = $result->fetch_assoc()) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$mysqli->close();

PDO

$result = $pdo->query("SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True");
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
  foreach ($row as $k=>$v) {
    echo "$k : $v";
    echo "<br />"; 
  }
}
$result = null;
$pdo = null;
