Add a family member
Adds a new member to a family. Requires familyId and either userId (existing user) or email/name (non-user contact). Only family owners, members with canManageChildren, or HR_LOCAL admins can add members. A user cannot belong to multiple families. Parents/guardians automatically receive child management permissions.
Authorizations
Server-to-server authentication. Generate a token in the admin UI at
Settings → Developers → API Access. Send the raw token in the
Api-Token header — there is no Bearer prefix.
Tokens can be marked read-only at creation time, in which case the API
rejects any non-GET request with 403 Forbidden.
