legacyUserId property
The legacy Fitbit User identifier.
This is the Fitbit ID used in the legacy Fitbit APIs (v1-v3). It can be referenced by clients migrating from the legacy Fitbit APIs to map their existing identifiers to the new Google user ID. It must not be used for any other purpose. It is not of any use for new clients using only the Google Health APIs. Valid values are strings of 1-63 characters, and valid characters are lowercase and uppercase letters, numbers, and hyphens.
Output only.
