apiKeyId property
The globally unique, Google-assigned identifier (UID) for the Firebase API key associated with the App.
Be aware that this value is the UID of the API key, not the
[keyString](https://cloud.google.com/api-keys/docs/reference/rest/v2/projects.locations.keys#Key.FIELDS.key_string)
of the API key. The keyString is the value that can be found in the
App's configuration artifact
([AndroidApp](../../rest/v1beta1/projects.androidApps/getConfig) |
[IosApp](../../rest/v1beta1/projects.iosApps/getConfig) |
[WebApp](../../rest/v1beta1/projects.webApps/getConfig)). If
api_key_id is not set in requests to create the App
([AndroidApp](../../rest/v1beta1/projects.androidApps/create) |
[IosApp](../../rest/v1beta1/projects.iosApps/create) |
[WebApp](../../rest/v1beta1/projects.webApps/create)), then Firebase
automatically associates an api_key_id with the App. This
auto-associated key may be an existing valid key or, if no valid key
exists, a new one will be provisioned.
