How can i implement paypal checkout v2 server side / JS sdk

I'm trying to make an implementation for paypal using checkout.js, however, i need to store the details of the transaction once the payment it's completed but first, i'm having trouble getting the button values from the server side, my code goes as follows:
<script>
paypal.Buttons({
// Order is created on the server and the order id is returned
// Call your server to set up the transaction
createOrder: function(data, actions) {
return fetch('php/create.php', {
method: 'post'
}).then(function(response) {
return response.json();
}).then(function(orderData) {
return orderData.id;
});
},
onApprove: function(data, actions) {
return actions.order.capture().then(function(details) {
// Call your server to save the transaction
return fetch('/paypal-transaction-complete.php', {
method: 'post',
headers: {
'content-type': 'application/json'
},
body: JSON.stringify({
orderID: details.id
})
});
});
}
}).render('#paypal-button-container');
</script>```
<?php session_start();
// PayPal configuration
define('PAYPAL_CONFIG', [
'URL' => "https://api-m.sandbox.paypal.com/",
'CLIENT_ID' => 'xxx',
'SECRET' => 'xxx',
]);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, PAYPAL_CONFIG['URL'] . "v2/checkout/orders");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERPWD, PAYPAL_CONFIG['CLIENT_ID'] . ":" . PAYPAL_CONFIG['SECRET']);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-Type: application/json'
]);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = [
"intent" => "sale",
"redirect_urls" => [
"return_url" => "http://localhost:8888/index.php",
"cancel_url" => "http://localhost:8888/index.php"
],
"payer" => [
"payment_method" => "paypal"
],
"transactions" => [
[
"amount" => [
"total" => $_SESSION['price'],
"currency" => "USD"
]
]
]
];
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$response = curl_exec($ch);
$httpStatusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
$result = json_decode($response, true);
if (json_last_error() !== JSON_ERROR_NONE) {
error_log("Invalid JSON response: " . json_last_error_msg());
var_dump($httpStatusCode);
return false;
}
if (!$result) {
error_log("cURL request failed with HTTP status code: " . $httpStatusCode);
var_dump($httpStatusCode);
return false;
}
return $result;
Whenever i try to click the paypal button, i keep getting a console error saying that Error: Unexpected end of Json input and closes the paypal window almost immediately
I've tried debbuging with several methods but i can't get it working, any suggestions?

(That code is not for checkout.js , which is older and deprecated ; you're using the current PayPal JS SDK)
Anyway, this issue:
Error: Unexpected end of Json input
Occurs when your server-side code is outputting something other than a purse JSON string, such as a var_dump or other echo statement. Your create and capture routes must output only a JSON string, never any other text or HTML.
You can get a log of the response being outputted to the XHR request in your browser's dev tools -> Network tab.

PHP call not returning API data

I'm using this link to obtain Air Quality data from an API https://api-ninjas.com/api/airquality
I want to do this via PHP due to it being a requirement
I have my PHP file
<?php
// Display errors is set to on and should be removed for production
ini_set('display_errors', 'On');
error_reporting(E_ALL);
// Timing script execution
$executionStartTime = microtime(true);
$url='https://api.api-ninjas.com/v1/airquality?city=' . $_REQUEST['countryName'];
// Curl object is initiated
$ch = curl_init();
//Curl_setopt() takes three parameters(Curl instance to use, setting you want to change, value you want to use for that setting)
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$result=curl_exec($ch);
curl_close($ch);
$decode = json_decode($result, true);
$output['status']['code'] = "200";
$output['status']['name'] = "ok";
$output['status']['description'] = "success";
$output['status']['returnedIn'] = intval((microtime(true) - $executionStartTime) * 1000) . " ms";
$output['result'] = $decode['result'];
header('Content-Type: application/json; charset=UTF-8');
echo json_encode($output);
?>
and then my JavaScript Function
function getAirQuality(countryName) {
$.ajax({
method: 'GET',
url: "assets/php/getAirQuality.php",
data: {
countryName: countryName
},
headers: {
'X-Api-Key': 'API_KEY'
},
contentType: 'application/json',
success: function(result) {
console.log(result);
$('#aqCO').html(result['CO']['concentration'] + ' ppm');
$('#aqSO').html(result['SO2']['concentration'] + ' ppm');
$('#aqO3').html(result['O3']['concentration'] + ' g/m3');
$('#aqNO2').html(result['NO2']['concentration'] + ' ppm');
$('#aqPM2').html(result['PM2.5']['concentration'] + ' µg/m3');
$('#aqPM10').html(result['PM10']['concentration'] + ' µg/m3');
},
error: function ajaxError(jqXHR) {
console.error('Error: ', jqXHR.responseText);
}
});
}
However, the PHP file keeps complaining in the console Error: <br /> <b>Warning</b>: Undefined array key "result" in <b>C:\xampp1\htdocs\project1\assets\php\getAirQuality.php</b> on line <b>30</b><br /> {"status":{"code":"200","name":"ok","description":"success","returnedIn":"293 ms"},"result":null}
As you can see from the above website, the result should be like so
{
"CO": {
"concentration": 223.64,
"aqi": 2
},
"NO2": {
"concentration": 9.08,
"aqi": 11
},
"O3": {
"concentration": 26.46,
"aqi": 22
},
"SO2": {
"concentration": 0.78,
"aqi": 1
},
"PM2.5": {
"concentration": 4.04,
"aqi": 13
},
"PM10": {
"concentration": 6.23,
"aqi": 5
},
"overall_aqi": 22
}
I'm not sure what else it could be? I've tried result, results and data
UPDATE
So whilst I've got the data decoded fine
result
:
CO
:
{concentration: 223.64, aqi: 2}
NO2
:
{concentration: 19.71, aqi: 24}
O3
:
{concentration: 52.93, aqi: 44}
PM2.5
:
{concentration: 11.67, aqi: 37}
PM10
:
{concentration: 14.61, aqi: 13}
SO2
:
{concentration: 1.97, aqi: 2}
overall_aqi
:
44
I am trying to assign them to variable like so: $('#aqCO').html(result['CO']['concentration'] + ' ppm'); but it is returning Uncaught TypeError: Cannot read properties of undefined (reading 'concentration')

You can pass headers by creating an array and passing it via: CURLOPT_HTTPHEADER
$headers = ['X-Api-Key: API_KEY'];
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);

401 unauthorized ajax call error to Watson Assistant API

I am trying to make ajax request to Watson Assistant API from client side only, so I had this code in php which is working fine but when I tried to make it in jQuery I got 401 unauthorized error.
PHP:
$data['input']['text'] = $_POST['message'];
if(isset($_POST['context']) && $_POST['context']){
$data['context'] = json_decode($_POST['context'], JSON_UNESCAPED_UNICODE);
}
$data['alternate_intents'] = false;
$json = json_encode($data, JSON_UNESCAPED_UNICODE);
// Post the json to the Watson API via cURL.
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://watson-api-explorer.mybluemix.net/conversation/api/v1/workspaces/'.$workspace_id.'/message?version='.$release_date);
curl_setopt($ch, CURLOPT_USERPWD, $username.":".$password);
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
$result = trim( curl_exec( $ch ) );
curl_close($ch);
// Responce the result.
echo json_encode($result, JSON_UNESCAPED_UNICODE);
JS:
$.ajax({
url: apiUrl,
type: 'POST',
dataType: 'json',
data: {
message: message,
context: context
},
headers:{
'Authorization' : 'Basic' + btoa('f7be829c-ae6d-47d8-b2bd-65a40ad45aa' +':'+ 'hJcToxQ23Zk'),
},
contentType: 'application/json',
timeout:10000
})
Anything missing from the JS code?

Use a PHP variable in Javascript / Ajax without showing in the inspect element

i want to send emails with de mandrill api. I have mi apikey in a php var but when i do var apikey='<?php echo$apikey;?>'; this shows in the inspect elemnt.
its posibble hide, encrypt or something the variable with php, javascript, ajax or json?
this is and example of my code:
<?php
$apikey='aaaaaaaaaaaaaa';
?>
<script type="text/javascript">
var apikey='<?php echo$apikey;?>';
sendEmail();
function sendEmail() {
$.ajax({
type: 'POST',
url: 'https://mandrillapp.com/api/1.0/messages/send.json',
data: {
'key': apikey,
'message': {
'from_email': 'FROM_EMAIL_GOES_HERE',
'to': [{
'email': $('.email').val(), // get email from form
'name': $('.name').val(), // get name from form
'type': 'to'
}
],
'autotext': 'true',
'subject': 'EMAIL_SUBJECT_GOES_HERE',
'html': "Hey *|COOLFRIEND|*, we've been friends for *|YEARS|*.", // example of how to use the merge tags
'track_opens': true,
'track_clicks': true,
}
}
}).done(function(response) {
console.log(response); // if you're into that sorta thing
});
});
</script>

You can setup a php service and use curl to do the transferring work. Then just have AJAX do the front end work and send the subject/body/etc to the php service.

#Lifz works great for me
