April 30, 2026 | Coperniq API

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

Recent highlights

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: Invoice payments — GET /invoices/{invoiceId}/payments, GET /invoices/{invoiceId}/payments/{paymentId}, and POST /invoices/{invoiceId}/payments (optional paymentReference on create).
New: Quotes — full CRUD via GET/POST /quotes, GET/PATCH/DELETE /quotes/{quoteId}, GET /quotes/{quoteId}/pdf, POST /quotes/{quoteId}/send, and GET /opportunities/{opportunityId}/quotes.
New: Work order line items — PUT /work-orders/{workOrderId}/line-items replaces line items on service work orders (account type). GET /work-orders/{workOrderId} now includes lineItems when present.
New: Taxes — GET /taxes lists company tax rates with pagination and archived filtering.
New: Bills — full CRUD for project bills via GET/POST /bills, GET/PATCH/DELETE /bills/{billId}, and GET /projects/{projectId}/bills. Supports LINE_ITEMS and PERCENTAGE calculation methods.
Improvement: Nullable fields on PATCH /projects/{projectId}, PATCH /accounts/{accountId}, and PATCH /clients/{clientId} — pass null to clear a field (e.g. description, ownerId, primaryEmail) or any custom property.

v2 exposes the same routes under the /v2 prefix with the standard { status, message, data } envelope.
