Count people in or out
Workforce module
POST/occupancy-counters/{id}/countoccupancyCounters.count
Counts people in (positive) or out (negative) at a door. Crossing 80, 90 or 100 percent alerts the dispatchers. Requires `Idempotency-Key`; a replay returns the original response. A rule that refuses the request returns 422 with `refusal` and `reason`.
- Requires the capability safety.incident.write.
- OAuth scopes: safety.
- Send an Idempotency-Key header. A replay with the same key returns the original response.
- Error statuses: 400, 401, 404, 409, 422, 429. Errors are RFC 9457 problem details.
