API support of request forms - Submit or trigger submission of custom Wrike form programmatically

Hi All,

I have been using Wrike for a while now and have gotten a few integrations set up through the API. I was testing the UI for the custom request forms within Wrike and there's a lot of features I like and would like to use. I know I can make a form external for non-users, and embed it in a page which is good -- but is there a way to pass data into the form like formurl/?email_field=foo@bar.com

Failing that, can you trigger a form submission by POSTing data to the Wrike form from my own application / form?

Any ideas greatly appreciated!
