One embodiment of the present invention provides a system that converts authentication-tokens to facilitate interactions between applications. During operation, the system receives a command-execution request from a first application, wherein the command-execution request specifies a command to execute on a second application. Subsequently, the system verifies a first authentication-token included with the command-execution request. Next, the system translates the first authentication-token into a form associated with the second application to produce a second authentication-token. The system then modifies the command-execution request by replacing the first authentication-token with the second-authentication-token to create a modified command-execution request. Then, the system sends the modified command-execution request to the second application.
