April 15, 2026 | Coperniq API

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.
