I am using https://sandbox.dev.clover.com/v3/merchants/RCTST0000008099 as the request and the system generated token for this request. Authorization is Bearer token. I am getting "401 Unauthorized". Have tried apisandbox.dev.clover.com too and that fails as well. I understand that the MID assigned to this sandbox account is the normal one. I followed the instructions for retrieving the Token which returned a GUID. Any ideas? Using Postman for testing.
