    - `Value []string`

  - `Matchers param.Field[[]Matcher]`

    Body param: Matching patterns to forward to your actions.

    - `Type MatcherType`

      Type of matcher.

      - `const MatcherTypeAll MatcherType = "all"`

      - `const MatcherTypeLiteral MatcherType = "literal"`

    - `Field MatcherField`

      Field for type matcher.

      - `const MatcherFieldTo MatcherField = "to"`

    - `Value string`

      Value for matcher.

  - `Enabled param.Field[RuleNewParamsEnabled]`

    Body param: Routing rule status.

    - `const RuleNewParamsEnabledTrue RuleNewParamsEnabled = true`

    - `const RuleNewParamsEnabledFalse RuleNewParamsEnabled = false`

  - `Name param.Field[string]`

    Body param: Routing rule name.

  - `Priority param.Field[float64]`

    Body param: Priority of the routing rule.

    Routing rule status.

    - `const EmailRoutingRuleEnabledTrue EmailRoutingRuleEnabled = true`

    - `const EmailRoutingRuleEnabledFalse EmailRoutingRuleEnabled = false`
