Not response and not error using cURL - php

I'm working with cURL but i don't have any response and any error when I'm using it. I have looking for any answer on the web but i haven't found anything. Too appear "Resource id #478"
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $ep);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, "data=$json");
curl_setopt($ch, CURLOPT_USERPWD, "$this->username:$this->password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$response = curl_exec($ch);
curl_close($ch);
$json is an array and $ep is the url of the API with I'm working on.
When I use "echo $response", appear "Authorization Required"
So, the question is why don't I have any response and any error? Is the authentication maybe?
Thanks for any answer

paypal api curl refund getting error AUTHENTICATION_FAILURE

I am trying to implement paypal refund using php curl.
This is my code.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.paypal.com/v1/oauth2/token");
//curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Accept: application/json',
'Accept-Language: en_US'
));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, $clientId.":".$secret);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
$result = curl_exec($ch);
$json = json_decode($result);
$access_token=$json->access_token;
curl_close($ch);
$ch=curl_init();
$headers=array('Content-Type: application/json','Authorization: Bearer '.$access_token);
curl_setopt($ch,CRULOPT_HTTPHEADER,$headers);
curl_setopt($ch, CURLOPT_URL, "https://api.paypal.com/v1/payments/sale/".$paypal_transaction_id."/refund");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{}");
$result = curl_exec($ch);
$result_array=json_decode($result,true);
I got the access token successfully.
But, the following error occurs in refund.
"Authentication failed due to invalid authentication credentials or a
missing Authorization header."
What's wrong with my code?
Or
My PayPal account is a business account and there is no problem with receiving money (using php paypal api).
Look at https://developer.paypal.com/docs/platforms/get-started/ it says you need to fill out the PayPal Marketplaces and Platforms form to be approved.
Is this the problem?
Haha, I found the error.
It's just spell error.(curl_setopt($ch,CRULOPT_HTTPHEADER,$headers);)
not CRULOPT_HTTPHEADER , is CURLOPT_HTTPHEADER
and I have change code more simply.(using API v2)
$ch=curl_init();
$headers=array('Content-Type: application/json','Authorization: Basic '.base64_encode($clientId.':'.$secret));
curl_setopt($ch,CURLOPT_HTTPHEADER,$headers);
$refund_url="https://api.paypal.com/v2/payments/captures/".$order['paypal_txn_id']."/refund";
curl_setopt($ch, CURLOPT_URL, $refund_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{}");
$result = curl_exec($ch);
$result_array=json_decode($result,true);
curl_close($ch);

PHP CURL GET request return 401 error (Auth fail)

First I send a POST request with a login and a password (admin authorization) and get some fields.
Next, I need to send GET request to API (check that client email exists), but I receive CURL error: The requested URL returned error: 401
In Postman GET request is working, what I am doing wrong?
This is my GET Request:
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_URL, "www.myurl.com/clients?email=a#a.a");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_USERPWD, "myusername:mypassword");
$result = curl_exec($ch);
You have to pass query string in case GET.
try below updated code.
$qry_str = "?email=a#a.a"
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_URL, 'www.myurl.com/clients.php',$qry_str);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_USERPWD, "myusername:mypassword");
$result = curl_exec($ch);

PHP cURL GET request : You are not authorized to access this resource

I am facing varied issue. I am able to get response in POSTman but getting below error while using PHP code.
You are not authorized to access this resource
code as below:
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml','Accept: application/xml'));
$data = curl_exec($ch);
curl_close($ch);
Unfortunately, different cURL versions behave slightly different and so there is not one valid answer but several approaches that work for different cURL versions.
Here are two suggestions:
From Problems with username or pass with colon when setting CURLOPT_USERPWD
Try adding curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);, or instead CURLAUTH_BASIC.
Something that should always work:
If it won't help, add username and password directly into url like https://user:pass#host.com/path.
You shouldnt turn off certificate verification, instead, get a valid cert, they are for free using letsencrypt.
<?php
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . base64_encode($password)); //here is the change
curl_setopt($ch, CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml','Accept: application/xml'));
$data = curl_exec($ch);
curl_close($ch);
This is a really longshot and i know that but i have seen quite a few API's that work like that and since the OP seems not to have the documentation of the API i will post this as an answer in case it helps him solve his issue.
If above does not work try to base64_encode($username) as well

PayPal Rest API PHP cURL login/auth not working anymore

We set up a PayPal express checkout about 2 weeks ago which worked perfectly until a couple of days ago it didn't.
On PayPal the transactions is ok but when I try to log in with cURL to check the transaction the inital merchant/client login fails but cURL shows no error.
I know that PayPal is upgrading to TLS 1.2 and HTTP/1.1 but I did the test check were our server/site passed.
This is how I initated the communication with paypal (this worked until now):
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://paypal.com/v1/oauth2/token');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_USERPWD, 'CLIENT_ID:SECRET');
curl_setopt($ch, CURLOPT_POSTFIELDS, 'grant_type=client_credentials');
$result = curl_exec($ch);
Now if I print out $result its empty, if I print out curl_errno its 0 and curl_error also empty
so because of TLS 1.2 I modified the code like this
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://paypal.com/v1/oauth2/token');
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSLVERSION, 6);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_USERPWD, 'CLIENT_ID:SECRET');
curl_setopt($ch, CURLOPT_POSTFIELDS, 'grant_type=client_credentials');
$result = curl_exec($ch);
but it fails exactly the same as the previous code.
What could be the problem?
or is it possible that if the login is ok the result is empty?

XML Request Using CURL

I am using curl library to get the XML but getting error of connection with host. Following is my code, I have just removed the credentials.
$url="https://interface.callport.net:8080/P-RVWR-drcm01-cti/call/2142100570";
$curl_post_data = array(
"query_type" => 'caller_info',
"dnis" => '8883874944',
);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, base64_encode('webapi#fastfix:color43t'));
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $curl_post_data);
$result = curl_exec($ch);
if(curl_errno($ch))
{
echo 'Curl error: ' . curl_error($ch);
}
else
{
echo $result;
}
curl_close($ch);
It's SSL so this usually fixes the problem. cURL does not verify the certificate then.
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
[edit] I solved the problems. First the SSL as described above, then I removed the base64 encoding of the username and password, changed so the data is sent by GET instead of POST and lastly fixed the headers.
$url="https://interface.callport.net:8080/P-RVWR-drcm01-cti/call/2142100570?query_type=caller_info&dnis=8883874944";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, 'webapi#fastfix:color43t');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
