  • Secure Workflow Variables: Store sensitive data like locationId or calendarId in your automation platform’s secure storage (e.g., n8n’s Credentials, Zapier’s Custom Fields, Make’s Data Stores, or Pabbly Connect’s Secure Parameters).
  • Verify IDs: Double-check locationId, calendarId, and contactId in your GHL dashboard to avoid errors in your workflows.
  • Monitor Workflows: Regularly review your automation platform’s logs to ensure smooth operation and troubleshoot any issues.
