No available slot issue

My availability tool I created keeps showing no available slot in the next 7 or 14 days which is wrong because my calendar is fully open

Vapi Support BotAPP•9/5/25, 10:13 AM

I'm sorry to hear that your availability tool is showing no available slots even though your calendar is fully open. It sounds frustrating! Sometimes, this kind of issue can be caused by a mismatch between the tool's settings and your calendar, or by a syncing problem. Double-checking the calendar integration settings and ensuring everything is up to date might help. If you've already tried that, looking into any filters or restrictions set within the tool could also be useful. Let me know if there's anything specific you've noticed that might help narrow down the cause!

Try verifying your tool's calendar ID and timezone settings:
Go to your assistant's tool configuration and double-check that the calendarIdcalendarId and

timeZone

timeZone

fields are set correctly and match your actual calendar. An incorrect calendar ID or timezone is a common cause for "no available slot" issues, even if your calendar appears open.

Example:

{
  "calendarId": "primary",
  "timeZone": "America/New_York"
}

{
  "calendarId": "primary",
  "timeZone": "America/New_York"
}

Update these settings if needed, then test the availability tool again.

@Vapi Support Bot please confirm

"timeZone": {
"description": "Brisbane/Australia AEST (UTC +10:00)",
"type": "string",
"default": ""
},
"calenderId": {
"description": "The Google Calendar ID to check availability for.",
"type": "string",
"enum": [
"primary"

Could you confirm if you have explicitly set the

timeZone

timeZone

field in your tool configuration to "Australia/Brisbane""Australia/Brisbane" (matching your calendar's timezone), and not left it blank or set to a different value?

I think I left the value blank . It's just the calendarId that has the value set to primary @Vapi Support Bot

Set the
timeZone
timeZone
field in your tool configuration to "Australia/Brisbane""Australia/Brisbane" to match your calendar's timezone.
Here's how your configuration should look:

{
  "calendarId": "primary",
  "timeZone": "Australia/Brisbane"
}

{
  "calendarId": "primary",
  "timeZone": "Australia/Brisbane"
}

Save this change and test your availability tool again—leaving

timeZone

timeZone

blank can cause the "no available slot" issue even if your calendar is open.

See what the tool is reading but still no available slot

{
"timeMin": "2025-09-05T00:00:00+10:00",
"timeMax": "2025-09-05T17:00:00+10:00",
"timeZone": "Australia/Brisbane",
"daysToCheck": 7,
"businessHours": "09:00-17:00"
}

@Vapi Support Bot please confirm

Vapi Support BotAPP•9/5/25, 10:38 AM

Thank you for sharing your current configuration. Since your calendarIdcalendarId and

timeZone

timeZone

are set correctly and the tool is still not finding available slots, could you confirm if your Google Calendar has any hidden events, restrictions, or special event types (like "out of office" or "private") during the checked period that might block availability detection?

Even if your calendar looks open, such entries can sometimes prevent slots from being shown.
If possible, please check your calendar for any such entries and let me know what you find.

Nothing of such honestly

yielding-jadeOP•9/5/25, 10:44 AM

@Vapi Support Bot my calendar is fully open, no hidden event types

Vapi Support BotAPP•9/5/25, 10:45 AM

Try reauthorizing your Google Calendar integration:
Go to your Vapi Dashboard, disconnect the Google Calendar integration, and reconnect it by following the prompts to grant permissions again. This can resolve hidden permission or sync issues that sometimes cause the tool to show no available slots even when your calendar is open.

After reconnecting, test your availability tool once more to see if slots appear.
