500 Server Error when setting sandbox postback url

Question

Whenever I try to set the postback url of my sandbox account, I get a 500 server error. Its been happening for a good part of the day so far. To set the url, I'm going here: https://sandbox.google.com/checkout/inapp/merchant/settings.html

Is there a different link I can try? Or is something just messed up with Wallet at the moment?

Answer 1

Something is probably messed up with sandbox let me check with engineering. Does production environment work for you? Not completing a transaction - but the purchase dialog.
