Optional. |\n| `expiration` | `string (`[int64](https://developers.google.com/discovery/v1/type-format)` format)` Date and time of notification channel expiration, expressed as a Unix timestamp, in milliseconds.

Optional. |\n| `params` | `map (key: string, value: string)` Additional parameters controlling delivery channel behavior. Optional. For example, `params.ttl` specifies the time-to-live in seconds for the notification channel, where the default is 2 hours and the maximum TTL is 2 days.

Example: `{ \"name\": \"wrench\", \"mass\": \"1.3kg\", \"count\": \"3\" }`. |\n| `resourceId` | `string` An opaque ID that identifies the resource being watched on this channel. Stable across different API versions. |\n| `resourceUri` | `string` A version-specific identifier for the watched resource. |\n| `kind` | `string` Identifies this as a notification channel used to watch for changes to a resource, which is `api#channel`. |"]]
