Is it possible submit a form via URL?

I want to submit a webforms module created form from an external site. Is this possible? Does anyone have a good way?

I am basically want to submit my form like I do in Accela:

I would log into accela and be able to see all my submit data. I want to reproduce this via Web Forms.
