How to complete signing process of Widget without confirming email address

Hi there,

I am working on development of creating Widget by use of HTTP Call from C#.

I want to implement redirection from my application to get signing done uploaded document.

I got success to redirect to signing Url and I also got success to redirect to my application.

But What I am seeing here that agreements is created when signer will confirm email address from his email.

I would like to avoid add email address during signing process and consequently not willing to confirm email address.

I am using redirection to get document signed.

Can anyone help me here ?
