Build your Google Calendar and Vapi integrations.
Vapi serves as a trigger that monitors your calendar events and initiates automated workflows when specific events occur. When a calendar event is triggered—such as an upcoming meeting, scheduled appointment, or calendar update—Google Calendar functions as an action by automatically executing AI-powered voice calls based on those calendar events. This integration enables you to send automated voice reminders before scheduled meetings, initiate customer calls when calendar events occur, or execute outbound calls triggered by your Vapi scheduling activities, connecting Vapi's scheduling capabilities with Google Calendar's conversational AI technology to automate your communication workflows.

How to setup Google Calendar and Vapi in 5 easy steps
Add your app to your Make scenario
Log into your Make account and add the app module you want to connect, such as Google Calendar or Vapi, to your automation workflow. Once added, click the button to create a new connection. This step begins the process of linking your external application with Make so they can communicate and work together to automate your tasks.
Set up your Google Cloud project
For Google apps like Google Calendar, visit the Google Cloud Platform website and create a new project by selecting 'Create or select a project' and then 'New project.' Give your project a descriptive name and click 'Create.' This project acts as a secure bridge between Make and your Google services, allowing them to safely share information with your permission.
Enable the Google Calendar API
Inside your Google Cloud project, go to 'APIs & Services' and then 'Library.' Search for 'Google Calendar API,' click on it, and press the 'Enable' button. This activation tells Google that your project needs permission to access calendar data, which allows Make to read and manage calendar events on your behalf as part of your automated workflows.
Get your Vapi API key
If you're connecting Vapi, log into your Vapi account and navigate to 'Build' and then 'Vapi API Keys' in the sidebar. Copy your Private Key and store it securely. If you need to generate a new key, simply click 'Add Key.' This key functions like a secure password that authorizes Make to access your Vapi account and perform automated actions for you.
Enter your credentials and connect
Return to Make and enter the required information to finalize your connection. For Google Calendar, click 'Sign in with Google' and complete the authentication process. For Vapi, paste your API key into the designated field. Once you save these credentials, Make will verify the connection works properly, and you'll be ready to build automated workflows between your connected applications.
