We have received a number of emails about clients not seeing any result when blocking because their script was waiting for a different response format. That's why we added a custom response option.

How to add custom response

In order to add a custom response when an ajax request from a form is blocked, you need to place an array in the config.php file. 
In this file you must add a variable with the obligatory name $ajax_response – it is important to name it that way. The variable should contain an array converted to JSON when the result is produced.

$ajax_response = array( 'test' => 'custom', 'company' => 'cleantalk');
