Administrators in Tallyfy can change any member’s role between Administrator and Standard and Light by going to Settings > Organization > Members and selecting a new role from the dropdown which takes effect immediately.
Tallyfy’s API lets admins update a member’s profile (name and timezone and optional fields like phone or job title) via a PUT request to /organizations/[org_id]/users/[user_id] and returns the full updated profile on success.
Tallyfy’s API lets you invite new users to your organization by sending a POST request with their email and name and role and a personal message to the /users/invite endpoint which returns the invited user’s profile with a status of “invited” until they accept.
