There are buttons in the Starbucks app on iOS for redeeming free apps and if I long press on the button, it shows a URL like
ua://75A6A5DC-D3BE-4056-9482-CEBCD5493F98. However, I don't know how to use the URL if I copy it. Safari won't navigate anywhere if I paste it in the address bar and press Go. If I just tap the button in the Starbucks app, it takes me to the App Store and automatically begins to redeem an app (presumably using a code embedded in, or retrieved from, the
ua:// URL, but I'm not sure on that—just my hypothesis).
I have Googled and can't find any information on the
ua URI. Can someone link me to documentation on what it means and how to use links like that?
