Hi. I am new to this forum and by no means want to come off as a "peon/noob" want to really know what's up with Google and why are they quitting Wallet & Checkout from being 100% open to all merchants?? Someone please correct me if I am wrong, for instance when I create a app using Google API for a Classifieds website why would I not be able to integrate Google API & Google Wallet's API together?? Need to know what are commonly used alternatives if the case is Google retired from offering the web these services.
