Release Notes

Welcome to the Coperniq API release notes. This section highlights noteworthy changes across endpoints, schemas, and docs.

Recent highlights

  • New: AHJs — GET /ahjs (search, filter, and lat+lng geo lookup), GET /ahjs/{id}, and PATCH /ahjs/{id} to update custom property values. v2 mirrors these under /v2 with the standard success envelope.
  • Updated: GET /properties — now documents the ahj record type (custom AHJ properties only) and adds an isCustom boolean to every property to distinguish custom columns from built-in standard ones.
  • New: Sections — line items on projects, invoices, and bills can now be grouped into named sections (matching quotes and work orders); read responses expose sectionName per line item.
  • New: Vendors — full CRUD via GET/POST /vendors, GET/PATCH/DELETE /vendors/{vendorId}, GET /vendors/search, and many-to-many project linking via POST/DELETE /projects/{projectId}/vendors/{vendorId}. Vendor-specific fields: vendorType (enum), website, and projectIds.
  • New: Labels — GET /labels (filter by type), POST /labels, GET /labels/{labelId}. type is WORK (work orders) or ASSET. v2 mirrors these under /v2 with the standard success envelope.
  • New: Assets — GET /assets (filter by account_id), POST /assets, GET/PATCH /assets/{assetId} (set isArchived: true via PATCH to archive). v2 mirrors these under /v2 with the standard success envelope.

New catalog categories and DELETE behavior change

Envelope product categories

17 new ProductCategory values are now available when creating or updating a catalog item with type=PRODUCT:

ROOF_COVERING, ROOF_UNDERLAYMENT, ROOF_MEMBRANE, ROOF_FLASHING, ROOF_VENT, WALL_CLADDING, WALL_TRIM, WEATHER_BARRIER, WINDOW, EXTERIOR_DOOR, SKYLIGHT, OPENING_FLASHING, GUTTER, DOWNSPOUT, INSULATION, SEALANT, SHEATHING.

tradeGroup remains optional. When provided, it must be ENVELOPE for these categories. For PATCH /catalog-items/{catalogItemId}, this validation is enforced when both category and tradeGroup are included in the patch payload (consistent with the current PATCH validation behavior).

Permitting service category

PERMITTING has been added to ServiceCategory (between OPTIMIZATION and RELOCATION) and is available when type=SERVICE.

DELETE /catalog-items/{catalogItemId} now returns 204 No Content

DELETE /catalog-items/{catalogItemId} previously returned 200 or 204 (sometimes with a body). It now always returns 204 No Content. Clients should no longer expect a response body on successful deletion.
