Insert onto Zoho from web form

Insert onto Zoho from web form

Hi, I've been asked by a client to get a form on his website to insert directly into Zoho recruit when submitted. I enquired about this before but was told we needed to embed one of your forms in an iFrame on the website. I've recently been forwared this link http://www.zoho.com/recruit/api.html which reads like it might do what the client wants but I can't make any sense of it. Is what I'm asking possible? Many thanks Eddie
