Status
Staff discount tiers, QR cards, and point-of-sale verification are retired in Campsite. Legacy bookmarks such as/discount, /discount/scan, /admin/discount, and /settings/discount-tiers redirect to the dashboard or settings. The former verification API returns HTTP 410 Gone.
If your organisation still needs a till-side staff discount process, handle it outside Campsite (or ask your Campsite admin about a future replacement).
