GCP Pub/Sub Trigger

The GCP (Google Cloud Platform) Pub/Sub Trigger fires a workflow whenever a message is sent to one of the topics defined on a given Google Pub/Sub integration or when the integration receives a connection event.

Node Properties

The GCP Pub/Sub Trigger requires choosing a Pub/Sub 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

Payload

The payload will include the received message in the data field. In the general case, a Google Pub/Sub Trigger workflow payload will look like the following:

{
  "applicationId": "555555555555eeeeeeeeeeee",
  "applicationName": "My Great Application",
  "data": {
    "attributes": {
      "key": "value"
    },
    "data": "my message",
    "disconnectReason": "Connection Lost",
    "failureReason": "Unauthorized",
    "id": "Google Cloud Pub/Sub message ID",
    "timestamp": "Google Cloud Pub/Sub message timestamp",
    "topic": "myGoogleTopic",
    "topics": [
      "myGoogleTopic",
      "anotherGoogleTopic"
    ],
    "type": "connect|message|disconnect|failure"
  },
  "flowId": "333333333333cccccccccccc",

  "time": Fri Feb 19 2016 17:26:00 GMT-0500 (EST),
