# Update a custom relationship type

PATCH https://api.withverifa.com/api/v1/relationship-types/{type_id}
Content-Type: application/json

Update label, inverse_label, description, or is_active. The slug
(`name`) cannot be changed after creation.

**Required scope:** `settings:write` (or legacy `identities:write`).


Reference: https://docs.withverifa.com/api-reference/relationship-types/update-relationship-type

## Authentication

## Request

### Path parameters

- `type_id` (string, required) — Relationship type ID (`crel_*`).

### Headers

- `Verifa-Version` (date, optional) — API version date string (e.g. `2026-02-01`). If omitted, the version pinned to your API key is used.
- `Key-Inflection` (enum, optional, default: snake) — Response key casing. Defaults to `snake`.
