| # /changes REST API | 
 |  | 
 | This page describes additions to the Gerrit change-related REST endpoints that | 
 | are added by the @PLUGIN@ plugin. | 
 |  | 
 | Please also take note of the general information on the | 
 | [changes REST API](../../../Documentation/rest-api-changes.html). | 
 |  | 
 | ### <a id="get-change"> Get Change options | 
 | _'GET /changes/[\{change-id\}](../../../Documentation/rest-api-changes.html#change-id)?@PLUGIN@--combined'_ | 
 |  | 
 | Adding the query parameter `@PLUGIN@--combined` adds a `CheckChangeInfo` entity | 
 | to the `plugins` list in | 
 | [`ChangeInfo`](../../../Documentation/rest-api-changes.html#change-info). All | 
 | fields reflect up-to-date information read from primary storage, not a secondary | 
 | index. | 
 |  | 
 | ### <a id="check-change-info"> CheckChangeInfo | 
 |  | 
 | The `CheckChangeInfo` describes check information on a change. | 
 |  | 
 | | Field Name             | Description | | 
 | | ---------------------- | ----------- | | 
 | | `combined_check_state` | The [combined state](#combined-check-state) of all checks on the change. | 
 |  | 
 | ### <a id="combined-check-state"> CombinedCheckState (enum) | 
 |  | 
 | The `CheckState` enum can have the following values: | 
 |  | 
 | * `FAILED`: At least one required check failed; other checks may have passed, or | 
 |   still be running. | 
 |  | 
 | * `WARNING`: All relevant checks terminated, and at least one optional check | 
 |   failed, but no required checks failed. | 
 |  | 
 | * `IN_PROGRESS`: At least one relevant check is in a non-terminated | 
 |   [state](rest-api-checks.md#check-state) (`NOT_STARTED`, `SCHEDULED`, | 
 |   `RUNNING`), and no required checks failed. Some optional checks may have | 
 |   failed. | 
 |  | 
 | * `SUCCESSFUL`: All relevant checks terminated successfully. | 
 |  | 
 | * `NOT_RELEVANT:` No checks are relevant to this change. |
