About Google Calendar's app

Triggers, searches, and actions

Limitations

• API rate limits apply per project and per user. Google Calendar API enforces quotas with per-minute limits per project and per-minute per project per user. Free Google accounts have a limit of 500 requests per day, while Google Workspace allows up to 1,000,000 requests per day.
• Data sent through the Google Calendar API must be in MM/DD/YYYY format regardless of your Google Calendar settings. Incorrect date formats can cause events to be created on wrong dates.
• In Google Calendar, all-day events end at midnight on the last day, meaning the end date is not included in the visible event duration. To fix this in Zapier, you should adjust the event's end date to be one day later.
• Repeated events are not supported with the New Event trigger. This is because repeated events have no end date, causing an infinite loop. Instead use the Event Starts trigger for repeated events.
• Events on calendars you subscribe to do not trigger the New Event trigger. This is because Google does not send accurate creation dates for subscribed calendars, using a default date of Jan 1, 1900 instead.
• When using the Event Start trigger, the "Time Before" field must be set to at least 16 minutes or more on Free plans due to polling intervals (15 minutes), or events might be missed.
• When using the Update Events action, only events created within the last 7 days show in the "Event" dropdown menu. To update older events, you must use a Find Event action to retrieve the Event ID, and then enter that ID as a custom value in the "Event" field of the Update Events action.
• Events on Google-generated calendars (like birthday calendars) can trigger multiple times due to Google changing event IDs, and are not recommended for triggers.
