Frequently asked questions

Ceven processes all time data using the RFC3339 UTC standard to ensure there is no drift between your location and the server. When you ask to schedule a meeting for 2pm Eastern Time, the agent converts that to the corresponding UTC timestamp before sending the request to the Google API. This prevents the common issue where events shift by several hours when shared across different regions. You can specify the time zone in your prompt, or the agent will default to the primary time zone configured in your Google Calendar settings to maintain consistency across all your scheduled events.
Yes. Ceven can list all calendars associated with your account, including primary, secondary, and shared calendars you have permission to edit. You can tell the agent to specifically place an event on your Work calendar or check availability on your Personal calendar. If you have not specified which one to use, the agent typically defaults to the primary calendar but will ask for clarification if it detects multiple calendars with similar names. This allows you to keep your professional and private lives separate while still using one AI agent to coordinate everything.
Ceven uses a look before you leap approach. Before calling the create event action, the agent runs a free busy query to verify the slot is actually open. If a conflict is found, the agent will not book the event. Instead, it will search for the next closest available slot that fits your criteria and suggest it to you or automatically book it if you have given the agent permission to resolve conflicts on its own. This prevents the messy overlap of meetings and eliminates the need for manual reconciliation after the fact.
Ceven uses Google OAuth 2.0 to access your data. When you connect, you are redirected to a secure Google sign in page where you can see exactly which permissions Ceven is requesting. We only ask for the scopes necessary to read, write, and manage your calendars. Once you grant access, Google provides a refresh token that we store encrypted. We use this token to generate short lived access tokens for each individual request. You can revoke this access at any time through your Google Account security settings, which immediately cuts off all agent access.
Ceven is subject to the Google Calendar API rate limits. For most users, this is never an issue, but if you attempt to sync thousands of events in a single second, Google may return a 403 rate limit exceeded error. To handle this, Ceven implements exponential backoff, meaning it will wait a few seconds and try again automatically. If you are running a massive migration of events, the agent will process them in batches to ensure the API quota is not exhausted, ensuring that your calendar remains stable and responsive throughout the process.
Ceven can create recurring events using RRULE strings, allowing for daily, weekly, or monthly repetitions. It can also manage exceptions to these series. For example, if you have a weekly Monday sync but need to move only next Monday to Tuesday, the agent uses the get event instances tool to find the specific ID for that one occurrence. It then patches that individual instance without affecting the rest of the series. This ensures your long term schedule remains intact while allowing for the flexibility needed for one off changes.
Yes, as long as you provide the email addresses of the guests. When the agent creates an event, it adds the guests to the attendee list. Google then handles the delivery of the invitation email and the tracking of RSVP statuses. Ceven can also check the RSVP status of guests by reading the event details, allowing it to notify you if a key stakeholder has not yet accepted the invite. This creates a closed loop where the agent not only schedules the meeting but also ensures that the right people are actually attending.
Ceven stays in sync using a combination of polling and webhooks. If you delete an event directly in the Google Calendar app, the agent will see that the event ID no longer exists the next time it queries your schedule. If you have a workflow set up to trigger based on event changes, the watch events tool will notify Ceven of the deletion in near real time. This ensures that any downstream tasks, such as canceling a linked Zoom room or notifying a client via email, are triggered immediately after the manual deletion occurs.
