How to use it
Check if there is an API kit for your programming language, if there isnt, connect to our servers manually.
Add a few extra lines to your email validation function which is called from your member registration page. The following is an example in PHP language:
..
function checkEmail($email) {
include_once("undorg/php/rest/undisposable.inc.php"); // include the API kit
if(!undorg_isDisposableEmail($email)) { // check if disposable email
.. // old procedures remain here
} // add this line to close the conditional statement
}
..
?>
Thats all. Very simple...
