There is no archive flag on a code and this cannot be undone. Nothing else breaks, and nothing else changes either. Referenced by value from a person's per diem entries, which the v2 public API does not expose. Those are plain string values with no foreign key behind them, so every record that already carries this code keeps it — the value simply stops appearing in the list. To retire a code while keeping it valid on existing records, `PATCH` it with `{ "isActive": false }` instead. ## OpenAPI ````yaml /openapi.yaml delete /per-diem-code/{id} openapi: 3.0.3 info: title: BuildingSwell Public API version: 2.0.0 description: > The BuildingSwell v2 public API. Every request needs an `X-API-Key` header, and every key is scoped to one organization, so you only ever see your own data. Base URL: `https://app.buildingswell.com/api/v2` Most resources share the same CRUD and query shape. Read the [standard endpoints](/guides/standard-endpoints) and [querying](/guides/querying) guides once and the rest of this reference follows the same rules.
