I'm developing a chrome extension and would like to charge for it. I've noticed based on the following documentation that the suggested way of achieving this is via a js api https://developer.chrome.com/webstore/money
What I don't understand is how do I make sure no end user is tampering with the client's code, causing a failed request to be considered as a successful one (using a breakpoint, and overriding the returned value from the relevant api call).
