Integration Downlink

Use this node to push a message as a downlink to a configured integration — for example, forwarding a command from the rule chain to an external MQTT broker or HTTP endpoint managed by a ThingsBoard integration, or relaying device RPC responses to an IoT platform via an integration connector.

• Integration — required. The integration to which downlink messages will be pushed. Selected by UUID from the list of configured integrations in your ThingsBoard instance.

1. Push the entire incoming message to the configured integration for downlink processing.
2. If the submission succeeds, forward the original message via Success.
3. If the integration does not exist, is disabled, or submission fails, route via Failure.

Incoming message — originator: DEVICE.
