Mutating requests (POST, PATCH, DELETE) accept an optional Idempotency-Key header (up to 255 characters). Retrying a request with the same key and the same body returns the original result instead of repeating the operation; reusing a key with a different body fails. Keys are scoped to your organization — keys chosen by other tenants can never collide with yours. Use a stable identifier from your system (for example your own record id plus the action) rather than a random value per attempt.

Reference Data
Read-only catalogs (equipment, charge codes, special requirements) referenced by id from other resources.
Every catalog also answers on its short top-level path, so GET /v1/charge-codes and GET /v1/reference-data/charge-codes are the same endpoint. The documented /reference-data/* form is canonical — it keeps the catalogs grouped here as more are added (port codes, cities, zip codes) — and the short form is a convenience alias.
