Any trick to use external CURL inside a hook?

[Remitur]

Hello.

 

I'm writing a hook that need to do a CURL towards an external site.

Very same PHP code (out of WHMCS but in the very same hosting space) works fine, but that code inserted into an hook get just a "404 error"...  😟

The code is this:

if (!defined("WHMCS"))
    die("This file cannot be accessed directly");

function checkuserdata($vars) {
    logActivity('here I am', 0);
    $email = $vars['email'];
 
// https://www.mailcheck.ai/ 
 
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.mailcheck.ai/eamail/' . $email);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);
    curl_close($ch);
    $response2=json_decode($response);
    $debug = var_export($response2, true);
    logActivity("response: ".$response, 0);
    logActivity("debug: ".$debug, 0);
    if ($response2->disposable OR !$response2->mx)
        { array_push($errors, "Your email address is not valid");
        }  
  
    return $errors;

}

add_hook("ClientDetailsValidation",1,"checkuserdata");

So, I guess... same option in curl_setopt needs to be configured someway different, but... what option?

(note: this call to mailcheck.ai is used to check not only the validity of the user's email address, but also that he is not using a disposable email for some kind of fraud attempt)

You have a typo. 

eamail

Yeah should be 

https://api.mailcheck.ai/email/

and not

 

https://api.mailcheck.ai/eamail/
