inventory.duplicate.resolved is the broad fan-out event. When we close a duplicate report on hotel X, every Pro+ organization with at least one active mapping pointing at X is notified, regardless of who originally filed the duplicate. If your downstream system caches the hotel id you mapped to, this is your signal to invalidate that cache.

​
When it fires

When a ReferenceHotelDuplicateReport is resolved by our team. The same event id may be delivered to many subscriptions (one per receiving org).

​
Required plan

Pro and above.

​
Recipients

Every organization with at least one partner_mapping_result whose matchedReferenceHotelId is either the original or the duplicate hotel id.

Payload

{
  "id": "del_…",
  "eventId": "evt_…",
  "type": "inventory.duplicate.resolved",
  "apiVersion": "2026-06-01",

Fields

FieldTypeNotes
data.reportIdUUIDThe duplicate report that was closed.
data.originalHotelIdUUIDThe canonical reference hotel we kept.
data.duplicateHotelIdUUIDThe reference hotel that was merged or dismissed.
data.resolution"FIXED" | "DISMISSED"FIXED means the duplicate was real and merged. DISMISSED means we determined the two hotels are genuinely different.
data.resolvedAtISO timestampWhen the report transitioned.

​
What to do

  • If resolution = FIXED and any of your mappings point to duplicateHotelId, those mappings will be redirected to originalHotelId server-side. You should invalidate any cached reference data and consider re-fetching the mapping result.
  • If resolution = DISMISSED, no mapping changes — but you may still want to record that we explicitly considered and rejected the duplicate.

Example: cache invalidation (Python)

@app.post("/hooks/mapping")
def receive(request):
    if not verify_webhook(request.headers["X-Webhook-Signature"], request.body, SECRET):
        return Response(status=401)
    payload = json.loads(request.body)
    if payload["type"] != "inventory.duplicate.resolved":
        return Response(status=204)

    data = payload["data"]
    if data["resolution"] == "FIXED":
        cache.delete_many([
            f"hotel:{data['duplicateHotelId']}",
            f"hotel:{data['originalHotelId']}",
        ])
    return Response(status=200)
