Hello! 

Thanks in advance for the help. I am creating a Shopify Flow that will trigger Klaviyo to send an email to a specific list of customers when I turn a new product in a specific collection to active. 

This will allow me to alert customers who have previously purchased a product in a specific collection that a new product has been added to that collection. 

Here is my flow:

I have input all of the correct information into the “Create a Campaign” action on the flow: API Key, List ID, Template ID, Sender Email Address, Sender Name, Subject, Campaign Name - I also enabled smart sending, just in case we add several products to the collection at a time - it won’t bombard customers with a bunch of the same email. 

When I turn the flow on, the “Checked if...” portion of my flow is successful, but this is the error message I receive regarding the Create a Campaign. 

All of the blacked-out information is correct. 

I appreciate the help! I would really love to see this flow work.
