# REST Authentication Interrupt

This strategy reaches out to a REST endpoint resource whose job is to 
dynamically calculate whether the authentication flow should be interrupted given the following parameters:

| Parameter           | Description                                                                 |
|---------------------|-----------------------------------------------------------------------------|
| `username`          | Authenticated principal id.                                                 |
| `service`           | The identifier (URL) for the requesting application.                        |
| `registeredService` | The identifier of the registered service matched and found in the registry. |

On a successful operation with a status code of `200`, the response body is 
expected to contain the JSON payload whose syntax and structure is identical to what is described above.
