How to connect Google Cloud Storage and Postmark
Create a New Scenario to Connect Google Cloud Storage and Postmark
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 Storage, triggered by another scenario, or executed manually (for testing purposes). In most cases, Google Cloud Storage or Postmark will be your first step. To do this, click "Choose an app," find Google Cloud Storage or Postmark, and select the appropriate trigger to start the scenario.
