I am working on Box integration with Zoho, So that I may able to sync Zoho And Box.com in such a way that I can login to Box.com and get my folders/files directly in zoho crm module's section such that when I create/upload folders/files into zoho crm' record, it should directly create/update in box.com. 

I have seen sample like this into another CRM, this is done using IFrames in records.

Now I want to use Iframe in  my record's detail page. 
And want to get help to get this task done.

Please give a correct idea/path to me to get this task done.
Thanks
