We are using Klaviyo on Shopify. We would like Klaviyo to email us when we are not present at the time of delivery or when the delivery is complete.
I know there is a feature on Shopify that allows us to be notified when a delivery is complete, but there is no notification feature for when we are not there.
I know that we can't email individually in Klaviyo, but can we update the customer data on Klaviyo via API and send it using the flow?
If so, which API should I use and what values should I set in the customer data?
