When Klaviyo and Google Calendar operate independently, marketing teams often face significant delays in scheduling events. For instance, when a new campaign is launched in Klaviyo, the corresponding event needs to be manually entered into Google Calendar. This leads to discrepancies in event timing and details, as marketers must cross-reference email lists and campaign specifics. The marketing team wastes hours each week on manual data entry, which could be better spent on strategy and execution.

Top Ways to Automate Klaviyo & Google Calendar

Automated Event Reminders: Automatically send personalized email reminders via Klaviyo to customers who have registered for events in Google Calendar, ensuring they never miss an important date.
Seamless Campaign Scheduling: Sync your Klaviyo email campaigns with Google Calendar events, allowing for targeted promotions that align with upcoming events, maximizing engagement and attendance.
Real-Time Customer Insights: Capture and analyze customer interactions from both platforms in one place, enabling data-driven decisions and enhancing your marketing strategies based on actual engagement metrics.

How to Build the Klaviyo → Google Calendar Sync

In Klaviyo, navigate to the 'Webhooks' section and create a new webhook that triggers on the 'Campaign Sent' event.
Set the webhook URL to point to your intermediary service that will handle the data transfer.
In the payload, extract the necessary fields such as 'campaign_name', 'recipient_list', and 'send_time'.
In your intermediary service, parse the incoming JSON data from Klaviyo and format it according to the Google Calendar API requirements.
Use the Google Calendar API endpoint POST https://www.googleapis.com/calendar/v3/calendars/primary/events to create a new event.
Construct the event JSON body using the extracted 'campaign_name' as the event summary, 'send_time' as the start time, and include any additional details in the description.
Authenticate the request to the Google Calendar API using OAuth 2.0 to ensure proper access rights.
Send the formatted JSON to the Google Calendar API endpoint.

Developer Warnings & API Gotchas

Ensure that the 'send_time' from Klaviyo is in ISO 8601 format, as Google Calendar requires this specific format for date and time.
Be cautious with time zone differences; Klaviyo may send times in UTC, while Google Calendar may require local time adjustments.
When creating events, avoid duplicate entries by checking existing events in Google Calendar that match the 'campaign_name' and 'send_time' before posting.
