Getting error while sending http request via curl - php

Question

I want to send charging request through php which I have sent via postman and it worked, but when I try this with php I m getting error response.
I have tried to send the request using curl and used function to send the request. But, after hitting the php I m getting the response that "invalid request" .
Here is the code snippet:
<?php
define('TML_CHARGE_URL2', 'http://sandbox-apigw.mytelenor.com.mm/v1/mm/en/customers/products/vas');
$client_id="MDq0MdGtZUGZWfanE8k2fva7GsLvwS0I";
$client_secret="GEzAxTE6YYSfLEAD";
$accessToken="ytSxhvjSUfNEurD5M6SOJPm6XAfu";
/* CP & Product Codes */
$cpid="15";
$login="apigwtest";
$password="apigwtestpwd";
$client_id="175612092873562378";
$msisdn="9791000601";
$prod_code = "APIGW_TEST";
$requestParamList = array("cpID" => $cpid,
"clientTransactionId" => $client_id,
"loginName" => $login,
"password" => $password,
"id" => array (
"type" => "MSISDN",
"value" => $msisdn
),
"productCode" => $prod_code
);
function callAPI($apiURL, $requestParamList) {
$jsonResponse = "";
$responseParamList = array();
$JsonData =json_encode($requestParamList);
$postData = 'JsonData='.urlencode($JsonData);
$ch = curl_init($apiURL);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
echo $status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //get status code
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($postData),
'Authorization: Bearer ytSxhvjSUfNEurD5M6SOJPm6XAfu'
)
);
echo $jsonResponse = curl_exec($ch);
$responseParamList = json_decode($jsonResponse,true);
return $responseParamList;
}
function oneshotpayment($requestParamList) {
return callAPI(TML_CHARGE_URL, $requestParamList);
}
function subscription_payment($requestParamList) {
return callAPI(TML_CHARGE_URL2, $requestParamList);
}
echo subscription_payment($requestParamList);
?>
The error response is like below:
{
"transactionId": "",
"timestamp": "2017-08-13T17:28:24+06:30",
"recipientMsisdn": "",
"code": "500.023.003",
"error": "Internal Server Error",
"message": "Request input is malformed or invalid"
}

You need to change your callAPI method.
1) You dont need to do urlencode after you have done json_encode
2) Remove unnecessory concatination of 'JsonData='. in string.
change you method like below
function callAPI($apiURL, $requestParamList) {
$postData = "";
$responseParamList = array();
$postData =json_encode($requestParamList);
$ch = curl_init($apiURL);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);
echo $status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //get status code
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($postData),
'Authorization: Bearer ytSxhvjSUfNEurD5M6SOJPm6XAfu'
)
);
echo $jsonResponse = curl_exec($ch);
$responseParamList = json_decode($jsonResponse,true);
return $responseParamList;
}
