Thanks for sharing the details! To help diagnose the issue, could you confirm whether the startDateTime and endDateTime values you are sending to the Google Calendar integration are in ISO 8601 format and explicitly include the "America/Chicago" timezone? This will help narrow down if the problem is with the datetime formatting or the timezone handling. If you need more guidance, the Vapi Google Calendar integration documentation has best practices for time zone handling. Source: - Vapi Google Calendar Integration Documentation

To help resolve the time error:
Could you please share the exact startDateTime, endDateTime, and timeZone values that are being sent to the Google Calendar integration when the event is created? This will help determine if the issue is with the datetime formatting or the time zone handling. For reference, all datetime fields should be in ISO 8601 format and the timeZone should be explicitly set to "America/Chicago" as per the Vapi Google Calendar integration documentation.

Make sure that when you trigger google.calendar.event.create, you are passing the startDateTime and endDateTime fields in ISO 8601 format and explicitly include the "America/Chicago" timezone in the timeZone field of the payload. For example:

{
  "summary": "Consultation",
  "startDateTime": "2025-05-27T14:00:00",
  "endDateTime": "2025-05-27T14:30:00",
  "timeZone": "America/Chicago"
}

{
  "summary": "Consultation",
  "startDateTime": "2025-05-27T14:00:00",
  "endDateTime": "2025-05-27T14:30:00",
  "timeZone": "America/Chicago"
}

This ensures Google Calendar interprets the time correctly. Double-check that your prompt and tool logic are not just mentioning the timezone, but actually passing it in the event creation call.

To avoid time errors, make sure your assistant's prompt or tool configuration explicitly sets the timeZone field to "America/Chicago" when creating the Google Calendar event. For example, ensure your event creation payload includes:

{
  "summary": "Appointment",
  "startDateTime": "2025-05-30T14:00:00",
  "endDateTime": "2025-05-30T14:30:00",
  "timeZone": "America/Chicago"
}

{
  "summary": "Appointment",
  "startDateTime": "2025-05-30T14:00:00",
  "endDateTime": "2025-05-30T14:30:00",
  "timeZone": "America/Chicago"
}

This ensures Google Calendar interprets the time correctly. Double-check that your prompt or backend logic always passes the correct timezone value when scheduling events.

To avoid time errors, make sure when creating the Google Calendar event you explicitly set both the startDateTime and endDateTime in ISO 8601 format and include the timeZone field as "America/Chicago". For example:

{
  "summary": "Appointment",
  "startDateTime": "2025-05-27T14:00:00",
  "endDateTime": "2025-05-27T14:30:00",
  "timeZone": "America/Chicago"
}

{

  "startDateTime": "2025-05-27T14:00:00",
  "endDateTime": "2025-05-27T14:30:00",
  "timeZone": "America/Chicago"
}

Double-check that your assistant's code or tool call includes these fields as shown above to ensure the correct time is reflected in Google Calendar.

Ensure all tools use the exact same time zone and ISO 8601 date-time format without conflicting offsets.
