JSON

{
  "Type" : "AWS::IoT::TopicRule",
  "Properties" : {
      "RuleName" : String,
      "Tags" : [ Tag, ... ],
      "TopicRulePayload" : TopicRulePayload
    }
}

YAML

  RuleName: String
  Tags: 
    - Tag
  TopicRulePayload: 
    TopicRulePayload

For URI Request parameters use format: ...key1=value1&key2=value2...

For the CLI command-line parameter use format: --tags "key1=value1&key2=value2..."

For the cli-input-json file use format: "tags": "key1=value1&key2=value2..."

Required: No

Type: Array of Tag

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the topic rule name. For example:

{ "Ref": "MyTopicRule" }

For a stack named My-Stack (the - character is omitted), a value similar to the following is returned:

MyStackMyTopicRule12ABC3D456EFG

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

Arn

The Amazon Resource Name (ARN) of the Amazon IoT rule, such as arn:aws:iot:us-east-2:123456789012:rule/MyIoTRule.

Examples

The following example declares an Amazon IoT rule.
