[SOLVED] How to setup correct cURL request for X Post?

Issue

I have an API to track the shipment, the API request is below and worked well as excepted,

 curl -X POST 
     --header '17token:xxxxxxxxxxxxxxxxxxxxxxxxx'
     --header 'Content-Type:application/json'
     --data '[{"number":"RR123456789CN"}]'
     https://api.17track.net/track/v1/register

Here is my cURL code to get the response.

<?php

// started curl
$curl = curl_init();

curl_setopt_array($curl, [
    CURLOPT_URL => "https://api.17track.net/track/v1/register",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "POST",
    CURLOPT_POSTFIELDS => "number:RR123456789CN", // SOMETHING IS WRONG HERE.

    //data '[{"number":"RR123456789CN"}]'

    CURLOPT_HTTPHEADER => [
         "17token:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
         "header 'Content-Type:application/json"
        ],
]);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
    echo "cURL Error #:" . $err;
} else {
    echo $response;
}
?>

The above code is showing error.

{"code":0,"data":{"errors":[{"code":-18010013,"message":"Submitted data is invalid."}]}}

I have tried all kinds of data structures like :


 1. CURLOPT_POSTFIELDS => "RR123456789CN", 

 2. CURLOPT_POSTFIELDS => "[{number:RR123456789CN}]",
  
 3. CURLOPT_POSTFIELDS => "{number:RR123456789CN}",   
          
 4. CURLOPT_POSTFIELDS => '{number:RR123456789CN}',   
                
 5. CURLOPT_POSTFIELDS => '{number:RR123456789CN}',    
                    
 6. CURLOPT_POSTFIELDS => "data '[{number:RR123456789CN}]'",

 7. CURLOPT_POSTFIELDS => "{\"number\": \"RR123456789CN\"}",

 8. CURLOPT_POSTFIELDS => "[{\"number\": \"RR123456789CN\"}]",

but all the above data structures are failing and showing the same error.

  1. I think I am doing something wrong with X POST / POST or

  2. I am failing to request properly.

Edit

After doing some research I have written new code..

<?php

// setting the main url
$url = 'https://api.17track.net/track/v1/register';

// the tracking id as array
$post_data = array (
'number' => 'RR123456789CN',);

// start
$ch = curl_init();

// URL
curl_setopt($ch, CURLOPT_URL, $url);

// Returntransfer = true
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

// Post = true
curl_setopt($ch, CURLOPT_POST, 1);

// Header # 1
curl_setopt($ch, CURLOPT_HEADER, "17token:xxxxxxxxxxxxxxxxxxxxxxxxx");

// Header # 2
curl_setopt($ch, CURLOPT_HEADER, 'Content-Type:application/json');

// posting tracking id
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

// Getting data in a string ($output)
$output = curl_exec($ch);

// error msg if fails
if ($output === FALSE){

    echo "cURL Error:" . curl_error($ch);
}

// turning off the cURL
curl_close($ch);

// Printing the output.
print_r($output);
?>

Now i am getting {"code":401,"data":{"errors":[{"code":-18010002,"message":"Access token is invalid."}]}} error.

Note : Token is valid and correct, i think something is wrong with my code.

Thank you.


Solution

You have to send your data as raw body:

$curl = curl_init();
$data = array(0 => array("number" => "CM436202796IN"));
$data = json_encode($data);

curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.17track.net/track/v1/register',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_POST => true,
  CURLOPT_POSTFIELDS => $data, // Mistake is here
  CURLOPT_HTTPHEADER => array(
    '17token: xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    'Content-Type: application/json'
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;
