Two gates apply: (1) the order must be flagged as freight, and (2) at least one freight quote must be accepted. The default token TTL is 24 hours; pass `ttl_seconds` to override within the 300-second .. 7-day band. The returned URL is the canonical document share path (rendered by the Lambda's document token handler); it requires no further authentication beyond the token. The canonical handler emits an `freight.bol_generated` activity log entry and a `freight.bol_generated` realtime broadcast. Idempotent on `Idempotency-Key`. Requires the `orders:write` scope. ## OpenAPI ````yaml /openapi.yaml post /freight_orders/{id}/bol openapi: 3.1.0 info: title: Arcus ERP Public API version: 1.0.0 description: > Arcus ERP public REST API. Designed for external integrations and data migration. **Authentication.** Bearer token (API key) via the `Authorization` header. Format: `Authorization: Bearer ark_live_ent__` (or `ark_test_*` for sandbox). API keys are issued per-entity in **Settings > Developers > API Keys**. **Entity scoping.** The entity is encoded in the API key prefix; routes are flat (e.g. `/v1/accounts`, `/v1/orders`, `/v1/products`). A small set of platform endpoints (migration, reconciliation, events, webhook endpoints, API keys) use the `/v1/entities/{entity_id}/...` form -- those are noted in their tags. **Key capabilities.** - Related-resource hydration via `?expand[]=` (see `x-arcus-expand` on each resource). - Cursor-based pagination (`starting_after` / `ending_before` / `limit`). - Idempotency via the `Idempotency-Key` header. - Webhook events for asynchronous notification. - Conditional requests / ETag for cache validation. servers: - url: https://api.arcuserp.com/v1 description: Arcus ERP API (accepts both live `ark_live_*` and test `ark_test_*` keys) - url: https://dev-api.arcuserp.com/v1 description: >- Dev sandbox API (test-only data, accepts `ark_test_*` keys against dev RDS) security: [] paths: /freight_orders/{id}/bol: parameters: - name: id in: path required: true schema: type: string format: uuid post: tags: - Freight summary: Generate a tokenized Bill of Lading URL description: > Mints a short-lived signed URL pointing at the order's tokenized BOL document.
