Make a wp_remote_post when not logged in - php

Question

Hi i'm developing a plugin which adds a new field to the order (WooCommerce). The field needs to make an ajax request to a file in my plugin, that file then needs to make a cURL request to another website (or wp_remote_post). But i'm experiencing difficulties when making the request.
I can't get the ordinary cURL to work nor the wp_remote_post function.
Here's a snippet of the cURL in my file which the ajax requests to.
<?php
$shipping_place = array(
'country_code' => $country_code,
'postcode' => $postcode,
'street' => $street,
'number_of_droppoints' => $number_of_droppoints
);
$auth = array(
'Content-Type: application/json',
'Authorization: Basic '. base64_encode('user:password')
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, $auth);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $shipping_place);
$result = curl_exec($ch);
if(curl_errno($ch)){
$msg = 'Curl error: ' . curl_error($ch);
} else {
$result = json_decode($result['body']);
if ( $result->status == 'error' ) {
echo $result;
}
pred($result);
echo $result->result;
}
curl_close ($ch);
?>

Solved: I had to localize the wp-admin script.
That would use the wp function like this
<?php wp_localize_script( $handle, $name, $data ); ?>
Reference here.
