Batch create carrier lane preferences
Batch create or update carrier lane preferences (e.g. CSV upload). Accepts API-key or session/bearer auth so both integrations and the web app can call it. Returns per-batch created/updated/failed counts + row errors.
Authentication: Supports API key and bearer token authentication.
Authentication
Bearer authentication of the form Bearer <token>, where token is your auth token.
Headers
A unique key (up to 255 printable ASCII characters, e.g. a UUID) that makes a retry of this request safe. Envoy stores the response for 24 hours; a retry with the same key and the same request returns it again with Idempotent-Replayed: true instead of running twice. The same key with a different request returns 422 idempotency_key_reused; while the first request is still running, 409 idempotency_key_in_progress. 5xx and 429 responses are not stored.
Request
Lane preferences (max 1000)
