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

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

Save and Activate the Scenario
After configuring Memberstack, Fillout, 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 Memberstack and Fillout integration works as expected. Depending on your setup, data should flow between Memberstack and Fillout (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Memberstack and Fillout
Fillout + Memberstack + Slack: When a new submission is received in Fillout, the automation finds or creates a member in Memberstack, then sends a welcome message to a dedicated Slack channel.
Fillout + Memberstack + Google Sheets: Upon a new submission in Fillout, member details in Memberstack are updated, and the submission data is logged in Google Sheets for analysis.
