Amazon Web Services provides a number of benefits for IT organizations which are:cost effective,dependable,flexible.

How  to integrate amazon in your site?
-> You need to get an access_key_id.
-> Authorized your Product API or Access_key.

How to get an access_key_id?
To get an access_key you have to create aws account from the below link:
https://aws-portal.amazon.com/gp/aws/developer/registration/index.html

After submitting the form you will get a mail from amazon. In that mail you will find a link link:
https://aws-portal.amazon.com/gp/aws/developer/account/index.html?ie=UTF8&action=access-key

From this link you will get your access key and private key. Store your public key(access key) and private key(secret key) in your config file. Using this access_key you can access all amazon  books and its details  in your page.

How to make your Product API or Access_key Authorized?
You need to create a two demo files and one function file using below code

1) Function file-  aws_signature.php
2) Example file- example1.php
3) Example file- example2.php

1)Make one file named as aws_signature.php
<?php
function aws_signature($location, $params, $public_key, $private_key)
{
$private_key=”your secret key”;
$method = “GET”;
$hostname = “ecs.amazonaws.”.$location;
$uri = “/onca/xml”;

// additional parameters
$params["Service"] = “AWSECommerceService”;
$params["AWSAccessKeyId"] = $public_key;

// GMT timestamp
$params["Timestamp"] = gmdate(“Y-m-d\TH:i:s\Z”);

// API version
$params["Version"] = “2009-03-31″;

// sort the parameters
ksort($params);

// create the query
$query = array();
foreach ($params as $param=>$value)
{
$param = str_replace(“%7E”, “~”, rawurlencode($param));
$value = str_replace(“%7E”, “~”, rawurlencode($value));
$query[] = $param.”=”.$value;
}
$query = implode(“&”, $query);
$string_to_sign = $method.”\n”.$hostname.”\n”.$url.”\n”.$query;
$signature = base64_encode(hash_hmac(“sha256″, $string_to_sign, $private_key, True));

// create request
$request = “http://”.$hostname.$url.”?”.$query.”&Signature=”.$signature;
// do request
$request=str_replace(” “,”+”,$request);
$response = @file_get_contents($request);
if ($response === False)
{
return False;
}
else
{
// parse XML
$parsed_xml = simplexml_load_string($response);
if ($parsed_xml === False)
{
return False; // no xml
}
else
{
return $parsed_xml;
}
}
//Note:You can use  $parsed_xml as you requested array.You will get all the records from this array.
?>

2)Make one file named as example1.php
//To get the data for particular ISBN.
<?php
include(‘aws_signature.php’);
$isbn=”your book isbn value”;
include(‘aws_signature.php’);
$public_key = “your public key”;
$private_key = “your private key”;

//You can select response group from this site:http://docs.amazonwebservices.com/_
AWSECommerceService/2008-03-03    /DG/index.html?ItemLookup.html

//Operation is ItemLookup for Particular item page.
$parsed_xml = aws_signature(“com”,  array(“Operation”=>”ItemLookup”,”ResponseGroup”=>”VariationSummary,_
SalesRank,Medium,Reviews,ItemAttributes,Offers,Images”,”ItemId”=>$isbn),   $public_key, $private_key);
?>

3)Make one file named as example2.php
//To get all books from amazon without knowing any book isbn value.
<?php
include(‘aws_signature.php’);
$public_key = “YOur public key”;
$private_key = “your private key”;
$new_keyword=”Your keyword”;

//Operation is ItemSearch for all books.
$parsed_xml = aws_signature(“com”,   array(“Operation”=>”ItemSearch”,”SearchIndex”=>”Books”,”ResponseGroup”=>”VariationSummary,_
SalesRank,Medium,Reviews,ItemAttributes,Offers,Images”,”Keywords”=>$new_keyword),  $public_key, $private_key);
?>
