Unexpected 401 response when calling haveibeenpwned API - php

Question

I dead stuck on an 401 response, another user suggested my header didn't included a leading white space for the API key field. I corrected it and am still receiving a 401. The API key should work, I paid for it last night, and regenerated a new one multiple times
my code:
<?php
$service_url = 'https://haveibeenpwned.com/api/v3/breachedaccount/?account=emailtest123#gmail.com';
$curl = curl_init($service_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
$ch = curl_init ($service_url);
curl_setopt ($ch, CURLOPT_HTTPGET, true);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'hibp-api-key: 8bcxxxxxxxxxxxxxx1bc11',
'user-agent: FAUstudentproject'
));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$returndata = curl_exec ($ch);
$status_code = #curl_getinfo($ch, CURLINFO_HTTP_CODE);
print_r($status_code);
print_r($returndata);
$curl_response = curl_exec($curl);
if ($curl_response === false) {
$info = curl_getinfo($curl);
$json = curl_close($curl);
die('error occured during curl exec. Additioanl info: ' . var_export($info));
}
curl_close($curl);
$decoded1 = json_decode($curl_response,true);
if (isset($decoded1->response->status) && $decoded1->response->status == 'ERROR') {
echo "hello";
echo curl_getinfo($ch);
die('error occured: ' . $decoded1->response->errormessage);
}
echo 'response ok!';
print_r(json_decode($json));
var_export($decoded1->response);
?>
The response:
401{ "statusCode": 401, "message": "Access denied due to missing hibp-api-key." }array ( 'url' => 'https://haveibeenpwned.com/api/v3/breachedaccount/?account=emailtest123#gmail.com', 'content_type' => NULL, 'http_code' => 0, 'header_size' => 0, 'request_size' => 0, 'filetime' => -1, 'ssl_verify_result' => 20, 'redirect_count' => 0, 'total_time' => 0.04700000000000000011102230246251565404236316680908203125, 'namelookup_time' => 0.01600000000000000033306690738754696212708950042724609375, 'connect_time' => 0.0309999999999999997779553950749686919152736663818359375, 'pretransfer_time' => 0.0, 'size_upload' => 0.0, 'size_download' => 0.0, 'speed_download' => 0.0, 'speed_upload' => 0.0, 'download_content_length' => -1.0, 'upload_content_length' => -1.0, 'starttransfer_time' => 0.0, 'redirect_time' => 0.0, 'redirect_url' => '', 'primary_ip' => '2606:4700::6812:ad0d', 'certinfo' => array ( ), 'primary_port' => 443, 'local_ip' => '2601xxxxxxxxxxxxxxxxx21d3', 'local_port' => 59096, 'http_version' => 0, 'protocol' => 2, 'ssl_verifyresult' => 0, 'scheme' => 'HTTPS', )error occured during curl exec.

Answer 1

You are using the wrong variable: replace curl_setopt($curl, CURLOPT_HTTPHEADER with curl_setopt($ch, CURLOPT_HTTPHEADER. You're using curl_init twice in your code.
Check your code to fix it, using only $ch or $curl, not both.
