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

Add the Omnisend Node
Select the Omnisend node from the app selection panel on the right.

Save and Activate the Scenario
After configuring Omnisend, Memberstack, 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 Omnisend and Memberstack integration works as expected. Depending on your setup, data should flow between Omnisend and Memberstack (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
