PHP api cURL POST How to get response? - php

Question

I'm trying to validate api data with POST request using cURL but getting no response.
API documentation
<?php
$url = "https://widget.packeta.com/v6/api/pps/api/widget/validate";
$data = array(
"Parameters" => array(
"apiKey" => "XXXXXX",
"id" => "9346",
)
);
$encoded = json_encode($data);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encoded);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$resp = curl_exec($ch);
$decoded = json_decode($resp);
print_r($decoded);
curl_close($ch);
?>
Does anyone know what is wrong?

Answer 1

SOLUTION:
Turns out i was missing CURL_HTTPHEADER.
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type: application/json",
"Accept: application/json"
));

Answer 2

Try to write:
$ch = curl_init();
instead of :
$ch = curl_init($url);
Eventualy you can use a try ... catch to get the error:
<?php
// Define variables
define('API_KEY', 'XXXXXX');
$url = "https://widget.packeta.com/v6/api/pps/api/widget/validate";
$id = "9346";
// Prepare data
$data = array(
"Parameters" => array(
"apiKey" => API_KEY,
"id" => $id,
)
);
$encoded = json_encode($data);
try {
// Initialize cURL
$ch = curl_init();
// Set cURL options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $encoded);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Execute cURL request
$resp = curl_exec($ch);
if($resp === false) {
throw new Exception(curl_error($ch));
}
// Decode response and print it
$decoded = json_decode($resp);
print_r($decoded);
// Close cURL session
curl_close($ch);
} catch (Exception $e) {
echo 'Error: ' . $e->getMessage();
}
?>
