How do you access the email associated with the license?

From within my app, not on the website. I tried ta.GetFeatureValue("Email") but that didn't work, and I don't see this mentioned anywhere in the example code or API documentation. I apologize if I'm missing it.

If you want to access the email from within your application then you'll have to add it as a custom license field that is readable from your app.: https://wyday.com/limelm/help/license-features/

That's what I was thinking - I was wanting to use it as a fallback/default value if the "Licensee" custom field was blank/not entered (for name or company). Thanks for the prompt answer (and perhaps log this as a low-priority feature request?)
