# Update a routing rule

`PATCH /v2/routing-rules/{routing_rule_id}`

Partially updates routing-rule metadata or configuration. Project scope is immutable.

## Path parameters

- `routing_rule_id` string, required

## Request body

- UpdateRoutingRuleRequest
  - `display_name` string
  - `description` string
  - `enabled` boolean
  - `expression` RoutingRuleExpression
    - `config` object
    - `cel` string — CEL expression used to match requests. Empty means the rule always matches.
  - `models_config` RoutingRuleModelsConfig
    - `mode` string — Load-balancing mode.
    - `models` RoutingRuleModel[]
      - `model` string
      - `display_name` string
      - `weight` number, double
      - `integration_id` string
  - `plugins` RoutingRulePlugin[]
    - `id` string — Plugin discriminator.
    - `language` string — Languages, regions and entity types are checked against the live pii-detection capabilities catalog when the rule is saved, not pinned here, so a language or region the detector gains becomes writable without a proto change.
    - `entities` string[] — Entity types to redact. Mutually exclusive with regions.
    - `on_failure` string
    - `threshold` number, double
    - `mask` string[]
    - `regions` string[] — Regions of coverage by ISO 3166-1 alpha-2 code, or ["all"]. Mutually exclusive with entities.
    - `entity_thresholds` object — Per-entity-type confidence cutoff. Every key must also appear in entities.
  - `priority` integer
  - `cache_config` RoutingRuleCacheConfig
    - `ttl` integer, required — Cache time to live in seconds. Maximum 259200 seconds (3 days).

## Response `200`
