How to enable the responsive signer experience

In order for your signers to experience the responsive signer page, you’ll need to specify the “uxVersion” option in your HelloSign.open() JavaScript call. This option supports two values:

Deprecated signer experience, the default for users who made an API call on their account before 11-14-15
Responsive signer experience, the default for users who made their first API call after 11-14-15.

Note: Premium branding is only available when the responsive UX is activated. If you've implemented any customizations, be sure to point your users to the version 2 UX so the changes are visible.

Embedded signing example:

In your JavaScript call to HelloSign.open(), be sure to pass the uxVersion parameter, like so:

<script type="text/javascript" src="//cdn.dev-hellosign.com/js/embedded.js"></script>
<script type="text/javascript">
HelloSign.init("CLIENT_ID");
HelloSign.open({
url: "SIGN_URL",
uxVersion: 2
});
</script>
