```

| Parameter | Type | Description |
| --- | --- | --- |
| states | [UseCancelablePromiseState](https://www.gooddata.ai/docs/gooddata-ui/latest/api-reference/sdk-ui/sdk-ui.usecancelablepromisestate/index.md)&lt;unknown, TError&gt;[] | cancelable promise states (useCancelablePromise return values) |

## Remarks

This is useful for useCancelablePromise composition - when you want to wrap multiple useCancelablePromise hooks in another hook, and keep the return value shape of the hook same as for useCancelablePromise.
