?> The button NEVER renders. The console is full of errors: SyntaxError: Unexpected end of JSON input Uncaught SyntaxError: Unexpected end of JSON input What am I missing? There is no explanation on the docs page. Also I need to ask: Is "Smart Checkout" the best option for the following case? All I need is to be able to have a button with a fixed price (that the user cannot change), and be reported (a simple POST to my back) if anyone makes a payment so I can change the user account to "premium" level. Thanks in advance.
