# Create tenant

`POST /tenant`

Resource: **Tenants**

## Request body

- **`id`** _(string)_
  Your identifier for the tenant. URL-path-safe: letters, digits, and `. _ : @ + -`. Up to 255 characters. Immutable — cannot be changed later.
- **`name`** _(string)_
  Display name. Defaults to `id` when omitted.
- **`metadata`** _(object)_
  Free-form JSON object. Stored and returned verbatim.
- **`environment_id`** _(string)_
  Which environment to create the tenant in. Required for session auth; ignored for API tokens (inferred from the token).

## Response body

- **`id`** _(string)_
  The tenant identifier — caller-chosen, URL-path-safe, and immutable once created. Composite primary key with `environment_id`, so the same value can exist independently in `development`, `staging`, and `production`. Must match `^[A-Za-z0-9._:@+-]{1,255}$`.
- **`environment_id`** _(string)_
  The environment this tenant belongs to.
- **`name`** _(string)_
  Display name shown in the dashboard. Defaults to the tenant `id` on create if not supplied; can be edited later via `PATCH /tenant/{id}`.
- **`metadata`** _(object)_
  Free-form JSON object stored verbatim. Truto does not interpret this field — use it for tier, region, billing plan, or any other customer attribute your app cares about.
- **`created_at`** _(string)_
  The date and time when the tenant was created.
- **`updated_at`** _(string)_
  The date and time when the tenant was last updated.
