I am watching teh video on this page: https://developer.squareup.com/docs/web-payments/overview and he says “I am using the sandbox script src, be sure to change that for production”, but he doesn’t say what to change it to! Can anyone point me at a document and/or send the URL?
You’ll want to change the URL to [Preformatted](http://web.squarecdn.com/v1/square.js) text as per our deploy the application documentation.
