I have been trying to get webhooks to work to get additional information (billing address and custom fields) about transactions.
I am using the code given below to test authentication. I have verified that login and key values are present, but keep getting the message "{ "message": "Authorization has been denied for this request." }"; I have regenerated via the key via sandbox->settings->webhooks just to make sure that was not the issue. I am able to succefully get a token and complete payment using the same login and key. Are there other settings in the admin interface which must updated? So far I have just created the key and the signature values.
<pre><code>
$login_transKey = AUTHNET_LOGIN . ':' . AUTHNET_TRANSKEY; //Login and Transaction Key of Authorize.net
$url = "https://apitest.authorize.net/rest/v1/eventtypes";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, $login_transkey);
$content = curl_exec($ch);
echo '<pre>'; print_r($content); die();
curl_close($ch);
</code></pre>
