Buildium's appliance API endpoints stop working October 19, 2026

Buildium deprecated its appliance endpoints on July 21, 2026, in favor of its new Inventory & Assets API. Starting Monday, October 19, 2026, every deprecated appliance endpoint returns 410 Gone.

Who this affects

Anything that reads or writes appliance records through the Buildium Open API: maintenance apps, warranty and asset trackers, custom reports and in-house scripts.

If you only use Buildium through its web app, nothing changes for you directly. If a tool connected to your Buildium account shows appliance data, ask whoever built it whether they've moved to the new endpoints.

Old endpoint → new endpoint

Deprecated Replacement
GET /v1/rentals/appliances GET /v1/inventoryassets
GET /v1/rentals/appliances/{applianceId} GET /v1/inventoryasset/{inventoryAssetId}
POST /v1/rentals/appliances POST /v1/inventoryasset
PUT /v1/rentals/appliances/{applianceId} PUT /v1/inventoryasset/{inventoryAssetId}
DELETE /v1/rentals/appliances/{applianceId} DELETE /v1/inventoryasset/{inventoryAssetId}
GET /v1/rentals/appliances/{applianceId}/servicehistory GET /v1/assetservicehistory/{inventoryAssetId}
GET /v1/rentals/appliances/{applianceId}/servicehistory/{serviceHistoryId} GET /v1/assetservicehistory/{inventoryAssetId}/{assetServiceHistoryId}
POST /v1/rentals/appliances/{applianceId}/servicehistory POST /v1/assetservicehistory/{inventoryAssetId}

The association endpoints (/v1/associations/appliances and everything under it) map to the same replacements.

How to check if you're affected

  1. Search your code for /rentals/appliances and /associations/appliances.
  2. Check your request logs for those paths over the last 30 days.
  3. Move each call to its replacement above. The path parameter changes from applianceId to inventoryAssetId, so check the request and response fields in Buildium's docs before you switch.
  4. Test in your Buildium API sandbox if you have one.
  5. Treat a 410 as permanent. Log it and alert on it instead of retrying.
