How do I route approvals to the right person?
Per-key notification channels work well for a single owner. Once more than one person can resolve approvals, you need a way to notify a team.
Approver groups: notify a team, not one inbox
On /dashboard/approval-groups, create a group and add org members to it (any existing team member, regardless of role: an approverwho isn't otherwise an admin or developer can still be on a group). Then, on a key's detail drawer, assign that key to the group.
From then on, every require_approval hold for that key emails every member of the group, in addition to any channels (Slack, Teams, Telegram, individual emails) already configured on the key. A key can belong to at most one group; a group can back as many keys as you like.
How the pieces add up
For any held call, the full recipient list is the union of: the key's own notification channels, its assigned approver group's members (if any), and the org-level fallback channels configured in Settings. Nothing here replaces the others. They layer, and duplicate emails are de-duplicated automatically.
Resolving the approval still works the same way regardless of how it was routed: from the notification, the in-app approvals inbox, or the Playground. See setting up approvals for the timeout and temporary-allow mechanics that apply once someone responds.
