Is JSON cart object available on receipt? It says it is in the wiki, however, when I ran some cursory tests I could only see it loaded on the cart and checkout pages.
I want to run script that will update another program after each sale. So I want to add something like this to the receipt template:
The PHP script would then process the database update.
Where $$$$$ is the total sale amount and ##### is a unique ID for the transaction (session ID?)
