# Update permission

> Change a Drive permission's role or expiration.

`googleDrive.updatePermission` change a Drive permission's role or expiration.

## Example

```ts theme={null}
import { automation, onDashboardRun } from "automate.ax"
import { googleDrive } from "automate.ax/google-drive"

export default automation("Update permission", () => {
  onDashboardRun({ title: "Update permission" })
  googleDrive.updatePermission({
    fileId: "file-id",
    permissionId: "permission-id",
    role: "reader",
  })
})
```

## Inputs

Provide `fileId`, `permissionId`, and at least one of `role` or `expirationTime`. Set `expirationTime: null` to remove an expiration. A new expiration must be in the future and no more than one year away. The action verifies that the existing permission belongs to a user or group before setting an expiration. A second argument with `account` selects a Google Account.

## Output

Returns the updated normalized permission.
