Looks like you answered your own question but for the benefit of the community, one of the DocuSign API recipes demonstrates all the steps for Embedded Signing.
Here is the full PHP version of the code. As you've found out, you can set the URL where users get redirected to after signing by setting the returnUrl property in your request body.
Here's the full PHP program for Embedded Signing. You can also find this here
<?php
// Input your info:
$integratorKey = '...';
$email = '[email protected]';
$password = '...';
$name = "John Doe";
// copy the templateId of an existing template here
$templateId = "C9D9D181-CE57-.....................";
// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";
