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

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!

I've disconnected and connected it back but nothing is working

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

calendarId

and

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:

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

Update these settings if needed, then test the availability tool again. [See documentation for more details](https://docs.vapi.ai/tools/google-calendar#tool-configurations) Source: - [Google Calendar Integration Documentation](https://docs.vapi.ai/tools/google-calendar#tool-configurations)

@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

field in your tool configuration to

"Australia/Brisbane"

(matching your calendar's timezone), and not left it blank or set to a different value? Source: - [Google Calendar Integration Documentation](https://docs.vapi.ai/tools/google-calendar#tool-configurations)

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

field in your tool configuration to

"Australia/Brisbane"

to match your calendar's timezone. Here's how your configuration should look:

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

Save this change and test your availability tool again—leaving

timeZone

blank can cause the "no available slot" issue even if your calendar is open. Source: - [Google Calendar Integration Documentation](https://docs.vapi.ai/tools/google-calendar#tool-configurations)

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" }

Thank you for sharing your current configuration. Since your

calendarId

and

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

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.

@Vapi Support Bot I'm still having the same issue. I have disconnected and reconnected but nothing new

Hi, could you please provide a call id so we can look at the logs?

I have a chat id because call ID doesn't even reach that point 45c1d4e4-289f-497a-9ae3-37b355beb8dd

Thank you for the chat id. We will look into it and get back to you
