## Update configuration properties

`client.APIGateway.Configurations.Update(ctx, params) (*Configuration, error)`

**put** `/zones/{zone_id}/api_gateway/configuration`

Updates API Shield configuration settings for a zone. Can modify validation strictness, enforcement mode, and other global settings.

### Parameters

- `params ConfigurationUpdateParams`

  - `ZoneID param.Field[string]`

    Path param: Identifier.

  - `Configuration param.Field[Configuration]`

    Body param

  - `Normalize param.Field[bool]`

    Query param: Ensures that the configuration is written or retrieved in normalized fashion

### Returns

- `type Configuration struct{…}`

  - `AuthIDCharacteristics []ConfigurationAuthIDCharacteristic`

    - `type ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristic struct{…}`

      Auth ID Characteristic

      - `Name string`

        The name of the characteristic field, i.e., the header or cookie name.

      - `Type ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicType`

        The type of characteristic.

        - `const ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicTypeHeader ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicType = "header"`

        - `const ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicTypeCookie ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicType = "cookie"`

    - `type ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicJWTClaim struct{…}`

      Auth ID Characteristic extracted from JWT Token Claims

      - `Name string`

        Claim location expressed as `$(token_config_id):$(json_path)`, where `token_config_id`
        is the ID of the token configuration used in validating the JWT, and `json_path` is a RFC 9535
        JSONPath (https://goessner.net/articles/JsonPath/, https://www.rfc-editor.org/rfc/rfc9535.html).
        The JSONPath expression may be in dot or bracket notation, may only specify literal keys
        or array indexes, and must return a singleton value, which will be interpreted as a string.

      - `Type ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicJWTClaimType`

        The type of characteristic.

        - `const ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicJWTClaimTypeJWT ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicJWTClaimType = "jwt"`

        Type: cloudflare.F(api_gateway.ConfigurationAuthIDCharacteristicsAPIShieldAuthIDCharacteristicTypeHeader),
      }}),
    },
  })
  if err != nil {
    panic(err.Error())
  }
  fmt.Printf("%+v\n", configuration.AuthIDCharacteristics)
}
