The integration cannot create Trello accounts, but can invite them to join the connected Trello teams. Provide the name, email, and the teams you’d like to add them to.
The new user will receive an email that invites them to Trello teams you’ve selected.

RoleUp offers the ability to update Trello team roles and memberships, as well as update board roles and memberships.
