I say yes, it is possible, by changing your web form action, what you can do is to write php script that makes xml rpc call to the OpenERP. and create a record of crm.lead model in OpenERP. By that way when normal user will submit the form it will create new record of Lead in OpenERP. without changing existing OpenERP module.

Can anyone elaborate on how to do this safely. Openerp has warnings about performing XML RPC correctly . . .

Any simple how to guide, even just for a few fields?

I really wanty my website form to fill in the openerp lead's fields automatically, having to do so manually each time is a pain.

Thanks in advance.
