Understanding JSON Variables

Site URL: http://www.lrpaperairplane.com

I'm new to this and am trying to understand how to inset a JSON variable into an order confirmation email. I've read the link on squarespace, but it just doesn't make sense to me how to do this.

Specifically, I have three digital products I would like sell. I need the email to have the digital link as well as the password to the page on the website. 

Background: I'm trying to do it this way because one of the digital files is too big to be uploaded, even compressed, to squarespace under the digital product page.

How do I customize this?

TIA!!

The JSON variables available in Confirmation Emails are specific to the order, not individual items that were ordered. For this reason, I don't think you can achieve what you need with JSON variables. 

For example, you can reference the customer's full name, their order number and whether or not they ordered a digital product, but you cannot add text to the email that is specific to which product they ordered. 

If you can provide a few more specifics about the products and what you are trying to achieve, we may be able to suggest an alternative approach.
