Save and Activate the Scenario
After configuring Formstack, Square, 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 Formstack and Square integration works as expected. Depending on your setup, data should flow between Formstack and Square (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Formstack and Square
Formstack + Square + Google Sheets: When a new form submission is received in Formstack, and a corresponding payment is created in Square, the details of both the form submission and the payment are added as a new row in a Google Sheet for easy tracking and record-keeping.
Square + Formstack + Slack: When a new payment event is registered in Square, the automation searches for corresponding information collected via Formstack and posts a notification to a designated Slack channel, providing details about the payment and associated form data.
