title: Is it possible to use Square's point of sale app without login?
body: <p>I'm developing an app that uses Square's point of sale app to make payment. However, as far as I know, our merchants need to login to the point of sale app before the payment can be made. My question is since we have the access token for Square-connect APIs, is it possible to use this token and other information such as <code>locationId</code>, <code>merchantId</code> etc. to make payments without logging into the point of sale app?</p>
