Frequently Asked Questions about Google Calendar + Harvest integrations

New to automation with Zapier? You're not alone. Here are some answers to common questions about how Zapier works with Google Calendar and Harvest

How does the integration between Google Calendar and Harvest work?

Our integration allows you to automatically create and manage Harvest time entries based on events in your Google Calendar. You can set it up so that whenever an event ends in your calendar, a corresponding time entry can be generated in Harvest. This means no more manual entry, as time tracking is directly linked to your calendar schedule.

What triggers are available when integrating Google Calendar with Harvest?

In our integration, you can utilize triggers like a new event in Google Calendar or an event ending. These triggers allow us to perform actions such as creating or updating time entries in Harvest whenever a specified calendar event occurs.

Can I customize which Google Calendar events create time entries in Harvest?

Yes, you can apply filters so that only specific events in your Google Calendar trigger the creation of time entries in Harvest. For instance, you might only want work-related events or meetings longer than 30 minutes to be logged as billed hours.

Is it possible to update existing time entries in Harvest through the integration?

Absolutely, our integration supports updating existing time entries based on changes to your events in Google Calendar. If an event details change, the corresponding entry in Harvest can be modified accordingly.

How does the integration handle deleted events from my Google Calendar?

When an event is deleted from your Google Calendar, we can automatically remove or update the associated time entry in Harvest if configured to do so. This ensures that your records remain consistent without manual adjustments.

Do I need any special permissions for this integration between Google Calendar and Harvest?

Both services will require proper authorizations: access permission for your selected Google Calendars and appropriate rights within your Harvest account to manage entries. Ensure both accounts are under one profile for seamless operations.

Can I integrate multiple calendars with my single Harvest account?

Yes, our setup supports integrating multiple calendars with one Harvest account. You can specify which calendars should trigger actions, allowing for precise control over how different types of events are managed across various schedules.
