Currently we can use querystring parameters to autofill form values (e.g. https://app.smartsheet.com/b/form/18f38f1ef40223457f7afe19cc0beba5d15?Field1=Value1%Field2=Value2) , which is an extremely useful feature. However, for authenticated forms, the querystring values are dropped during the authentication process if the user was not logged in when invoking the example link. This then requires work around where the user clicks the link, performs the login AND THEN go back to the link’s origin and clicks the link again to get the autofill to work in the form. We would love to see Smartsheet add functionality to maintain those values through the authentication process. While we use SAML for authentication, and the “relayState” attribute could help with this, I suspect you might need to use a more authentication agnostic approach.
