- Field Detail
  - AUTHORIZATION_PENDING
```
public static final ErrorObject AUTHORIZATION_PENDING
```
    The authorization request is still pending as the end user hasn't yet completed the user interaction steps (Section 3.3). The client SHOULD repeat the Access Token Request to the token endpoint (a process known as polling). Before each new request the client MUST wait at least the number of seconds specified by the "interval" parameter of the Device Authorization Response (see Section 3.2), or 5 seconds if none was provided, and respect any increase in the polling interval required by the "slow_down" error.
  - SLOW_DOWN
```
public static final ErrorObject SLOW_DOWN
```
    A variant of "authorization_pending", the authorization request is still pending and polling should continue, but the interval MUST be increased by 5 seconds for this and all subsequent requests.
  - EXPIRED_TOKEN
```
public static final ErrorObject EXPIRED_TOKEN
```
    The "device_code" has expired and the device flow authorization session has concluded. The client MAY commence a new Device Authorization Request but SHOULD wait for user interaction before restarting to avoid unnecessary polling.
