APPENThe sandbox runs the real rule engine. It uses no real money. You need a free account. It takes about ten seconds.
APPENCard issuing is not live yet. $50 covers your first month when issuing opens and locks $199/mo for your first 12 months. Places are filled in the order they are reserved.
Refundable in full, any time before issuing goes live — just ask.
Your rulebook and your place in the queue are recorded first, then you go to checkout. Issuing has no live date yet — if you would rather not pay ahead of one, email hello@getappen.com and we will hold a place without payment.
APPENEverything you have saved, shared, or reserved.

APPENAnyone with the link sees the card and its rules as raw JSON. Nothing about your account is shown.
Every rule is opt-in. Nothing here is on unless you turn it on — and every rule you turn on checks every purchase, top to bottom.
For developers. This is the same rulebook as JSON — edit it and the list follows, or copy the request and run it against your own key.
Pick a starting point — every number and store can be changed after.
