### id

> **id**: `string`

Defined in: [packages/react-native/src/types/NotificationIOS.ts:482](https://github.com/marcocrupi/react-native-notify-kit/blob/main/packages/react-native/src/types/NotificationIOS.ts#L482)

Intent identifiers used by the system to provide category context to Siri.

Use `IOSIntentIdentifier.START_CALL` for call categories. Legacy
`START_AUDIO_CALL` and `START_VIDEO_CALL` values remain accepted for source
compatibility, but both map to Apple's unified start call intent identifier.
Categories read back from iOS can return `START_CALL` for call intents.
