Methods and systems for linking untrusted applications to server systems

摘要

An electronic device with a display detects an input in a user interface for a second application not associated with a server system. In response to detecting the first input, the device sends a first request from the second application to a first application associated with the server system. In response to the first request, the device sends a first command from the first application to the server system on behalf of the second application. The first command is a command for performance of a first operation at the server system. The first operation corresponds to the input detected by the device. The device receives a voucher, or an indication that a voucher has been created, at the second application pre-authorizing performance of a predefined second operation at the server system upon receipt, by the server system, of a second command from the second application.
