How to integrate chatovod chat into the site?

Question

PHP

I bought a PRO on the website chatovod.com, I wanted to welcome my database. Asks for a handler URL on my site. They don't say anything about a handler. What data to send, what to process? I wish I hadn’t been too lazy myself and would have written my own chat :(
Actually, the very essence of the issue
The site is self-written. The user’s id and nickname are stored in the session. write.

Is it just fate to insert a frame on the site?

<iframe class="cchat" frameborder="0" marginheight="0" marginwidth="0" width="100%" height="400" style="width:100%;height:400px;border:none;" src="тут ссылка на ваш чат"></iframe>
