Managing HTTP topic rule destinations - Amazon IoT Core
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Managing HTTP topic rule destinations

You can use the following operations to manage your HTTP topic rule destinations.

Creating HTTP topic rule destinations

You create an HTTP topic rule destination by calling the CreateTopicRuleDestination operation or by using the Amazon IoT console.

After you create a destination, Amazon IoT sends a confirmation request to the confirmation URL. The confirmation request has the following format:

HTTP POST {confirmationUrl}/?confirmationToken={confirmationToken} Headers: x-amz-rules-engine-message-type: DestinationConfirmation x-amz-rules-engine-destination-arn:"arn:aws:iot:us-east-1:123456789012:ruledestination/http/7a280e37-b9c6-47a2-a751-0703693f46e4" Content-Type: application/json Body: { "arn":"arn:aws:iot:us-east-1:123456789012:ruledestination/http/7a280e37-b9c6-47a2-a751-0703693f46e4", "confirmationToken": "AYADeMXLrPrNY2wqJAKsFNn-…NBJndA", "enableUrl": "https://iot.us-east-1.amazonaws.com/confirmdestination/AYADeMXLrPrNY2wqJAKsFNn-…NBJndA", "messageType": "DestinationConfirmation" }

The content of the confirmation request includes the following information:

arn

The Amazon Resource Name (ARN) for the topic rule destination to confirm.

confirmationToken

The confirmation token sent by Amazon IoT Core. The token in the example is truncated. Your token will be longer. You'll need this token to confirm your destination with Amazon IoT Core.

enableUrl

The URL to which you browse to confirm a topic rule destination.

messageType

The type of message.

Confirming HTTP topic rule destinations

To complete the endpoint confirmation process, if you're using the Amazon CLI, you must perform the following steps after your confirmation URL receives the confirmation request.

  1. Confirm that the destination is willing to receive messages

    To confirm that the topic rule destination is willing to receive IoT messages, either call the enableUrl in the confirmation request, or perform the ConfirmTopicRuleDestination API operation and pass the confirmationToken from the confirmation request.

  2. Set topic rule status to enabled

    After you've confirmed that the destination can receive messages, you must perform the UpdateTopicRuleDestination API operation to set the status of the topic rule to ENABLED.

If you're using the Amazon IoT console, copy the confirmationToken and paste it into the destination's confirmation dialog in the Amazon IoT console. You can then enable the topic rule.

Sending a new confirmation request

To activate a new confirmation message for a destination, call UpdateTopicRuleDestination and set the topic rule destination's status to IN_PROGRESS.

Repeat the confirmation process after you send a new confirmation request.

Disabling and deleting a topic rule destination

To disable a destination, call UpdateTopicRuleDestination and set the topic rule destination's status to DISABLED. A topic rule in the DISABLED state can be enabled again without the need to send a new confirmation request.

To delete a topic rule destination, call DeleteTopicRuleDestination.
