Add new Wauld credential recipients to Mighty Networks space(s)

Once someone earns a Wauld credential, getting them into the right Mighty Networks Space, like an alumni or advanced-members area, usually takes a manual add. This Zap automatically adds new Wauld credential recipients as full members to a Space the moment their credential is issued, skipping the invite flow. It gives certified members instant access to the community that matches their achievement.
