Client bought a theme and gave me the purchase code, how can I download it?

Hi, I have this client who bought the Jupiter theme and sent me the license with purchase code. He wants me to design a site with that. How can I download the theme with the purchase code? Or is it even possible?

Maybe he will have to download it and then send me over the zip file?

Thanks much!

Here you will get idea how to collect Envato Purchase code

They will have to share it. Only the buyer will ever have access to downloads

You can create an app when setting it up which will help handle updates etc using the envato API
