Use case: I want to log in a user (in my SaaS) using Google Calendar and then create a voice assistant using Vapi that helps book meetings in the user’s calendar. The Vapi Create Assistant API (https://docs.vapi.ai/api-reference/assistants/create) has the option to connect dynamic credentials (using GoogleCalendarOAuth2AuthorizationCredential), which requires an authorizationId. What is this authorizationId, and how do I obtain it? I have set up custom OAuth with Google Calendar in my app and am getting access/refresh tokens for each user. How do I get the authorizationId from those tokens, or is there another way?

You can’t use your own Google OAuth tokens directly with Vapi. The

authorizationId

must come from a Google Calendar credential created in the Vapi dashboard. Vapi doesn’t support injecting per-user tokens via API. If you need per-user calendar access, handle booking in your backend using your own tokens, and trigger it from the assistant via a tool call.

checking if this is resolved/solved for you?
