Walmart API Search Products - php

Question

I am trying to get search products for a keyword
My code:
$searchquery = "ipod";
$api_endpoint = "http://api.walmartlabs.com/v1/search";
$postfields = "apiKey=". $appid ."&query=" . $searchquery;
//$postfields = array('apiKey' => $appid, 'query' => $searchquery);
$connection = curl_init();
curl_setopt($connection, CURLOPT_URL, $api_endpoint);
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, false);
//curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 0);
//curl_setopt($connection, CURLOPT_HTTPHEADER, $headers);
curl_setopt($connection, CURLOPT_POST, true);
curl_setopt($connection, CURLOPT_POSTFIELDS, $postfields);
curl_setopt($connection, CURLOPT_HEADER, true);
//curl_setopt($connection, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($connection, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($connection);
curl_close($connection);
print_r($api_endpoint);
print_r($response);
When i go in browser and visit api.walmartlabs.com/v1/search?apiKey={appid}&query=ipod , it shows results, but when i try to do with curl , it shows
"Action Not Found"
Here is the Screenshot
Any help would be appreciated.

Answer 1

looking on the doc (https://developer.walmartlabs.com/io-docs) it appears that the server expects a GET request.
Just replace your POST request with a GET request and all should be fine
$searchquery = "ipod";
$api_endpoint = "http://api.walmartlabs.com/v1/search";
$urlParams = "apiKey=". $appid ."&query=" . $searchquery;
$fullUrl = $api_endpoint . '?' . $urlParams;
$connection = curl_init();
curl_setopt($connection, CURLOPT_URL, $fullUrl);
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($connection, CURLOPT_HEADER, true);
curl_setopt($connection, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($connection);
curl_close($connection);
print_r($api_endpoint);
print_r($response);
