Send updated order confirmation (transactional) after changes made to Shopify order

Hi @NHI, welcome back to the community!

So you’re right, if you look at the standard Shopify events that the Klaviyo Shopify Plugin provides, there isn’t an event for Updated Order. See here:

• Shopify data reference

A few things you can consider if the updated order is an event you want to be able to captured in Klaviyo:

• You can look at Shopify Flow and trigger a Klaviyo Event via the Klaviyo Connector that passes in the information you want as a custom API Event.  I’d recommend this as long as the data and parameters you need are accessible.
• You can use a third party tool like Zapier or Alloy Automation.  You can learn more about them in the Klaviyo Integration directory.
• Finally, you can build your own custom API from Shopify’s API to Klaviyo’s API.  This is highly technical and will require a developer proficient with both Shopify and Klaviyo to implement. 

Hope this helps!
