["FORBIDDEN","DENIED_GREY_LIST"] errors

[hawaii-do]

I try to check spam from a signup form trough API. I'm using the Cleantalk\CleantalkAntispam library.

I'm calling the API with this method:

$_SESSION = array();
$_SESSION['ct_submit_time'] = time();
$cleantalk_antispam = new CleantalkAntispam('xxxxxxxxx',
$request->input('email'),
$request->input('first_name'),
"signup",
'signup'
);

And I receive this error

Cleantalk result: {"sender_ip":"188.63.198.137","sender_email":"","received":-1,"stop_words":null,"comment":"*** Forbidden. Please submit form again. Anti-Spam by CleanTalk. ***","blacklisted":0,"allow":0,"id":"82bdb4cb3e1336a12171b52f89483472","errno":0,"errstr":"","fast_submit":-1,"spam":0,"js_disabled":-1,"sms_allow":null,"sms":null,"sms_error_code":null,"sms_error_text":null,"stop_queue":0,"inactive":0,"account_status":1,"codes":["FORBIDDEN","DENIED_GREY_LIST"]}

So why it is forbidden ? What should I do ?

Hi @hawaii-do!
Judging by the result, sender_email is missing.
Check that an email is sent during registration.
The submit_time value is also not passed.
