Integrify customers can host html forms outside of the Integrify Portal if needed. Nothing special needed. HTML forms can post to our API or customers can use the Widget API with a guest account.
Configure any form to be completed by the Guest account to use the special "Requester" recipient. If you assign the Guest account directly, the form task will autocomplete without waiting for input.
Also, be sure to grant appropriate permissions to the Guest account to the process and the current publication status (i.e., grant Guest run permission for "Development" status if the process has a publication status of Development.
