How to connect Google Cloud Pub\Sub and Alegra
Create a New Scenario to Connect Google Cloud Pub\Sub and Alegra
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a Google Cloud Pub\Sub, triggered by another scenario, or executed manually (for testing purposes). In most cases, Google Cloud Pub\Sub or Alegra will be your first step. To do this, click "Choose an app," find Google Cloud Pub\Sub or Alegra, and select the appropriate trigger to start the scenario.

Add the Google Cloud Pub\Sub Node
Select the Google Cloud Pub\Sub node from the app selection panel on the right.

Save and Activate the Scenario
After configuring Google Cloud Pub\Sub, Alegra, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the Google Cloud Pub\Sub and Alegra integration works as expected. Depending on your setup, data should flow between Google Cloud Pub\Sub and Alegra (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Google Cloud Pub\Sub and Alegra
