i cannot cancel subscription id "7bcc42e3-9efa-491c-a0d9-fa9eca88eda5" because i remove sandbox application with active subscription
Did you mean you deleted the application while a subscription was active? If that was the case, of course your app cannot be authenticated with the clientID and secret as they are invalid. The subscription will expire anyway.
Did you mean that you’re trying to cancel your monthly subscription and you can’t find where to do it on this godforsaken ring central?
Using the RingCentral Phone for Desktop, you can dial or receive test calls, send and receive test SMS or Fax messages in your sandbox environment.
Download RingCentral Phone for Desktop:
Tip: switch to the "sandbox mode" before logging in the app:
