Particle Trigger

The Particle Trigger fires a workflow whenever an event is received on the selected Particle integration or the integration receives a connection event.

Particle Trigger

Node Properties

The Particle Trigger requires choosing a Particle integration, as well as at least one of the following events on which to fire the trigger:

  • Trigger on a connection
  • Trigger on a message (checked by default)
  • Trigger on a disconnection
  • Trigger on a failure to connect

After selecting a Particle integration, a summary of the event names that will cause the trigger to fire will appear beneath the selector.

Payload

The trigger’s initial payload includes a data object with the following properties:

  • coreid: A string representing the ID of the Particle device that published the event.
  • data: A string value associated with the published event.
  • name: The name of the event as a string.
  • published_at: An ISO date string indicating when the event was published.
  • ttl: An integer representing the TTL (time to live) of the published event, in seconds.

In the general case, a Particle Trigger’s initial payload looks like the following:

  "applicationId": "555555555555eeeeeeeeeeee",
  "applicationName": "My Great Application",
  "data": {
    "coreid": "myParticleDeviceId",
