Hey @Andromeda Maxing I can help you troubleshoot your Vapi to GoHighLevel workflow. Calendar integration issues are usually related to authentication, calendar permissions, or how the function is structured in Vapi. The most common issues are incorrect API credentials, the calendar ID not having proper write permissions, or the function call format not matching what GHL expects. I can review your workflow setup, check the function configuration, and get your appointment creation working properly. DM me and I'll help you fix it quickly.
