Integration checklist
- Bidirectional ticket / alert sync
Alerts raise tickets and status changes flow back without middleware.
- Asset / device mapping
Devices match to client records automatically after the initial mapping pass.
- Alert escalation rules
Severity maps to priority and on-call routing rules travel with the alert.
- Billing reconciliation
Seat counts reconcile to invoices automatically each cycle.
- Webhook / event support
Both sides expose event webhooks (API grades A and A).
Common bottlenecks & caveats
- Seat minimums apply (HaloPSA: 1, Rewst: none) — small tenants pay for unused units.
- Field mapping is not retroactive: records created before the integration is enabled usually need a one-time backfill.
