CJ API Product Catalog Search Service using REST

Hello everyone, I am a newbie when it comes to using the CJ APIs to try to get the information I require, so I managed to find some code that someone else had written and modified it slightly. It seems error-free and should in theory work. Here is the code:

CJ_API_call_test.php

<?php
// Commission Junction Product Catalog Search Service (REST) API
if(!isset($_GET["test"]))
{
  $keyword_string = "Mini";
}
else
{
  $keyword_string = $_GET["test"];
}
$keyword_string = urlencode($keyword_string); // handles spaces etc.
$count = "2";

// send request to API
$cURL = curl_init();
curl_setopt($cURL, CURLOPT_URL, 'http://xxx/CJ_API_test.php?keyword='.$keyword_string.'&amp;max='.$count);
curl_setopt($cURL, CURLOPT_HEADER, 0); // we do not want the header unless troubleshooting
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, 1);
$strPage = curl_exec($cURL);
curl_close($cURL);
echo($strPage);
?>

PHP:

CJ_API_test.php

<?php
$websiteid= "xxx"; // I've used the correct one
$CJ_DevKey= xxx"; // I've used the correct one here too
$currency="USD";
$advs="joined"; // results from (joined), (CIDs), (Empty String), (notjoined)
// begin building the URI and GETting variables passed
$targeturl="https://product-search.api.cj.com/v2/product-search?";
if (isset($_GET["keyword"]))
{
$keywords = $_GET["keyword"];
$keywords = urlencode($keywords);
$targeturl.="&amp;keywords=$keywords";
}
 
if (isset($_GET["max"]))
{
$maxresults = $_GET["max"];
$targeturl.="&amp;records-per-page=".$maxresults;
}
 
$targeturl.="&amp;website-id=$websiteid";
$targeturl.="&amp;advertiser-ids=$advs";
$targeturl.="&amp;currency=$currency";
// end building targeturl
 
$ch = curl_init($targeturl);
curl_setopt($ch, CURLOPT_POST, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$CJ_DevKey)); // send development key
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
$xml = new SimpleXMLElement($response);
curl_close($ch);
 
if ($xml)
{
foreach ($xml->products->product as $item) {
$link  = $item->xpath('buy-url');
$link  = (string)$link[0];
 
$title = $item->xpath('name');
$title = (string)$title[0];
 
$imgURL = $item->xpath('image-url');
$imgURL = (string)$imgURL[0];
 
$price = $item->xpath('price');
$price = '<br />$'.number_format($price[0],2,'.',',');
 
$merchantname = $item->xpath('advertiser-name');
$merchantname = (string)$merchantname[0];
 
$description = $item->xpath('description');
$description = (string)$description[0];
 
 
if($link != "")
$results .="<div id=\"product\">
<div id=\"product_img\"><a href=\"$link\" target=\"_blank\"><img src=\"$imgURL\"/></a></div>
<div id=\"product_link\"><a href=\"$link\" target=\"_blank\">$title</a></div>
<div id=\"product_desc\">".$description."</div>
<div id=\"product_price\"><a href=\"$link\" target=\"_blank\">".$price."</a></div>
</div><br /><br />";
 
}
}
 
if ($results == '') { $results = "<div id=\"product\">There are no available products at this time or no search parameters were specified.  Please try again later.</div>"; }
 
print $results;
// print curl_error($ch);
print "\n\r".$_GET["keyword"]."\n\r".$targeturl."\n\r";
var_dump(simplexml_load_string($response));
?>

PHP:

Now when I run the file CJ_API_call_test.php I get this result:

The problem is that I can't see the use of an invalid key, so what is going on?

Thanks.

 

I tried your code and I am getting the same thing thing. My key is 261 characters long, is that the right key?

 

This thread is old now but I'm having a similar problem. Only in my case it returns no results with this code example:

<?php
$websiteid= "MySiteID";
// register for your developer's key here: http://webservices.cj.com/ (input dev key below)
$CJ_DevKey= "MyDeveloperKey";
$currency="USD";
$advs="joined"; // results from (joined), (CIDs), (Empty String), (notjoined)
// begin building the URL and GETting variables passed
$targeturl="https://product-search.api.cj.com/v2/product-search?";
if (isset($_GET["keyword"]))
{
$keywords = $_GET["keyword"];
$keywords = urlencode($keywords);
$targeturl.="&amp;keywords=$keywords";
}
if (isset($_GET["max"]))
{
$maxresults = $_GET["max"];
$targeturl.="&amp;records-per-page=".$maxresults;
}
$targeturl.="&amp;website-id=$websiteid";
$targeturl.="&amp;advertiser-ids=$advs";
$targeturl.="&amp;currency=$currency";
// end building targeturl
$ch = curl_init($targeturl);
curl_setopt($ch, CURLOPT_POST, FALSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$CJ_DevKey)); // send development key
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
$xml = new SimpleXMLElement($response);
curl_close($ch);
if ($xml)
{
foreach ($xml-<span>></span>products-<span>></span>product as $item) {
$link = $item-<span>></span>xpath('buy-url');
$link = (string)$link[0];
$title = $item-<span>></span>xpath('name');
$title = (string)$title[0];
$imgURL = $item-<span>></span>xpath('image-url');
$imgURL = (string)$imgURL[0];
$price = $item-<span>></span>xpath('price');
$price = '
$'.number_format($price[0],2,'.',',');
$merchantname = $item-<span>></span>xpath('advertiser-name');
$merchantname = (string)$merchantname[0];
$description = $item-<span>></span>xpath('description');
$description = (string)$description[0];
if($link != "")
$results .="
$title
".$description."
".$price."
";
}
}
if ($results == '') { $results = "
There are no available products at this time or no search parameters were specified. Please try again later.
"; }
print $results;
?>

If you use the CJ API, can you please post an example that works? I have to admit that I did just copy this example from a website I found when Googling the problem. A couple of others didn't work either (whether it was on my PC or to a remote server that I uploaded it to.) I do have cURL installed. Ideally I'd prefer to use JavaScript for this, but I don't know a whole lot about coding to begin with.
