As reported by multiple people, the Integration with Google Calendar (for Tools "google_calendar_check_availability_tool" and "google_calendar_tool") are failing, with an obscure "Missing Nango configuration for tool type: google.calendar.availability.check" error. Call ID: 0199978e-6da9-744a-a782-5912c193b78a Timestamp: 09/29/2025 15:18 US Pacific Expected: An authenticated tool call to the integrated Google calendar Actual: Mysterious "Nango error" Note that the Integrations are connected, with proper scope, but Vapi insists on showing "Connected" (as opposed to "Disconnect") The Tools are set up. Their payload is not failing The authentication is clearly failing. Please advise a fix or workaround.

Use a 3rd party workflow manager

Hi Nate, To connect the Google Calendar to your Vapi assistant, please follow these steps: 1. Connect Google Calendar Account: - Navigate to the [Vapi Dashboard](https://docs.vapi.ai/tools/google-calendar#connect-google-calendar). - Go to Provider Keys > Tools Provider > Google Calendar. - Click the Connect button and follow the authorization prompts. 2. Create Calendar Tools: - Go to Dashboard > Tools page. - Click the Create Tool button and select Google Calendar. - Create desired tools: Google Calendar Create Event Tool or Google Calendar Check Availability Tool. Provide a specific name and descriptive details for each. 3. Add Tools to Assistant: - Navigate to Dashboard > Assistants page. - Select your assistant and go to the Tools tab. - Choose your calendar tools from the dropdown and click Publish. These steps should help you set up the Google Calendar integration. For detailed guidance, refer to the [integration documentation](https://docs.vapi.ai/tools/google-calendar).

I've also tried multiply times to do this and it does not work. It shows connect instead of connected. I've integrated Google in n8n and make.com and never had such issue. It is not only Nate's problem. A lot of people have same issue. Vapi needs to fix it..
