Settings, then Developers: hiding the widget for carts that hold only products you list by handle, or only digital items

Customer tag access: allowing or excluding logged-in customers by tag, and what happens at checkout

Order checking: tagging orders that are missing an AppstleID, and the email alert setting

Online store settings: adding the AppstleID to cart items, restoring the customer's choices and blocking the checkout button until the widget has loaded

Tagging orders with the day the customer chose, the POS setting, Geolocation country, Custom styles and your API key

What a visitor sees on your cart page when a rule hides the widget, and when it comes back

If a customer can't see the widget, check Widget visibility and Customer tag access first.

Hide widget for specific products takes product handles. A cart hides the widget only when every item in it is on your list: one other item brings the widget back.

Allow customers with these tags shows the widget only to logged-in customers who have one of the tags; leave it empty to allow everyone. Exclude customers with these tags wins over an allowed tag. Tags must match exactly, capitals included.

At checkout, customers that Customer tag access leaves out also don't see the rates you set up in the app.

Block the checkout button until the widget has loaded is for slow connections: customers can't check out before the widget has loaded. Ticking it adds a box for styling the blocked button.
