Custom Requisition Form

Custom Requisition Form

Hi.

I don't know if this has been covered, couldn't find any info in the forums. 

I'm trying to make my own requisition form. I just can't use the iframe listed in the settings. 

How can I acomplish this?

I already have the designed form for the requisition, I just don't know how to send the info back to Zoho Calendar. 

I see there's a Web API in the settings, but this doesn't seem to be functioning. 

Thank you.
