Unknown fields refused by name. container_sale_price/container_cost are refused outright. ## OpenAPI ````yaml /openapi/ehr-api.v1.yaml post /v1/clinics/{clinic_id}/inventory/items openapi: 3.1.0 info: title: ClinikEHR API version: 1.0.0 description: >- Server-to-server REST API for a clinic's own data, reached with a key the clinic (or a developer workspace) creates in the developer portal. Authenticate every request with `Authorization: Bearer `. Test keys reach only your workspace's own synthetic sandbox; live keys reach the clinic that created them. Lists wrap their rows as `{ data, has_more, next_cursor }`; single resources are returned directly. Errors are `application/problem+json` (RFC 9457) with a stable `code`. Write requests accept an `Idempotency-Key` header so a retry never repeats a change. See the guides for authentication, permissions, pagination, rate limits and retries. servers: - url: https://api.clinikehr.com security: - ApiKey: [] paths: /v1/clinics/{clinic_id}/inventory/items: post: tags: - Inventory summary: Create a catalogue item description: >- **Permission:** `inventory.items:write` Add a catalogue item.
