# How do I make my plugin support Cookiebot?
If you favourite plugins doesn’t support Cookiebot you are always welcome to ask the author to add support for Cookiebot.
Cookiebot provides a helper function to check if there is an active, working version of Cookiebot on the website.
The easiest way for at developer to implement Cookiebot support is to add a check for Cookiebot where tags are outputted to the visitor. 

This can be done following way:

```php
$scriptTag = ";
if(function_exists('cookiebot_active') && cookiebot_active()) {
$scriptTag = '<script'.cookiebot_assist('statistics').'>';
}
```

A users consent state can be be aquired through Cookiebots JS API.

The following properties are available on the Cookiebot object:
