Refresh Token User Id

The userId field on a RefreshToken record in Skarn Suite (the platform auth hub: SSO, tenancy, billing, entitlements, internal event bus) stores a specific piece of the data; it is a reference linking this RefreshToken record to the related record it belongs to, so the application can join them and present connected data together. In everyday use this is part of how RefreshToken records are created, displayed, validated, and reported, and it is grounded strictly in the real schema fact RefreshToken.userId: String.
