Save and Activate the Scenario
After configuring Formstack, JustCall, 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 JustCall integration works as expected. Depending on your setup, data should flow between Formstack and JustCall (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 JustCall
Formstack + JustCall + Slack: When a new form submission is received in Formstack, a call is initiated to the respondent using JustCall. After the call, a summary of the interaction is posted to a designated Slack channel for review and follow-up.
JustCall + Formstack + Google Sheets: When a new call is logged in JustCall, the automation searches for existing customer data in Formstack. If found, the Formstack entry is updated. Regardless, call details and Formstack data (if found) are consolidated and recorded in a Google Sheet.
